The antenna module 197 may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device 101. According to an embodiment, the antenna module 197 may include an antenna including a radiating element composed of a conductive material or a conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, the antenna module 197 may include a plurality of antennas (e.g., array antennas). In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

According to various embodiments, the antenna module 197 may form a mmWave antenna module. According to an embodiment, the mmWave antenna module may include a printed circuit board, a RFIC disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a designated high-frequency band (e.g., the mmWave band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., the top or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the designated high-frequency band.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 or 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device 101 may provide ultra low-latency services using, e.g., distributed computing or mobile edge computing. In another embodiment, the external electronic device 104 may include an internet-of-things (IoT) device. The server 108 may be an intelligent server using machine learning and/or a neural network. According to an embodiment, the external electronic device 104 or the server 108 may be included in the second network 199. The electronic device 101 may be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology or IoT-related technology.

Prior to a detailed description, various example embodiments will be described below with reference to an example of generating an avatar of a person. However, various example embodiments may also be applied to generating an avatar of an animal and/or a plant and/or generating a shape of an object.

FIG. 2 illustrates a system for avatar generation of an electronic device according to various example embodiments.

Referring to FIG. 2, a system 200 according to various example embodiments may include an electronic device 201 (e.g., the electronic device 101 of FIG. 1) and a server 208 (e.g., the server 108 of FIG. 1).

According to various embodiments, the electronic device 201 may include a function for avatar generation (or an avatar generating application). For example, the electronic device 201 may generate an avatar by recognizing a face of a person included in an image displayed on a display (e.g., the display module 160 of FIG. 1) (indicted by reference numeral 210), configuring (e.g., modeling) a face part of an avatar based on a result of the recognition (indicated by reference numeral 220), and rendering the configured face part (indicated by reference numeral 230). According to an embodiment, the electronic device may generate an avatar by further configuring body parts and/or clothes.

According to various embodiments, the electronic device 201 may analyze an image displayed on a display (e.g., the display module 160 of FIG. 1) (e.g., perform image processing) upon a request for avatar generation (e.g., execution of an avatar generation function) to extract feature information of a face region of an object (e.g., a person) included in the image and feature information of each component constituting the face (e.g., hairstyle, eyebrows, eyes, nose, mouth, beard, and/or accessories) so as to perform face recognition (indicated by reference numeral 210). The image may include an image (e.g., a preview image), which is acquired through a camera (e.g., the camera module 180 of FIG. 1) and being displayed on the display, or an image which is loaded from a memory (e.g., the memory 130 of FIG. 1) and displayed on the display. The face recognition (indicated by reference numeral 210) is understood by a person skilled in the art in the technical field of the disclosure, and thus a detailed description thereof will be omitted. According to an embodiment, the electronic device 201 may further perform body recognition and/or clothes recognition for extracting feature information related to a body and/or clothes.

According to various embodiments, the electronic device 201 may select a face base model and assets corresponding to respective components based on a recognition result (e.g., feature information of a face region and feature information of respective components), and arrange each of the selected assets in the selected face base model, so as to perform the face configuration 220. For example, the electronic device 201 may select a face base model based on a part of a recognition result (e.g., race, age, gender, and/or skin color) and select assets corresponding to respective components based on the other part thereof, and arrange each of the selected assets in the selected face base model to perform the face configuration (indicated by reference numeral 220).

According to various embodiments, the electronic device 201 may select a face base model and an asset by using mapping information 20 received (e.g., downloaded) from the server 208. The mapping information 20 may define how to configure the face of an avatar based on a result of the recognition of the image. The mapping information 20 may include a mapping table and assets. The mapping table may map feature information, which is related to a basic shape of a face, to a face base model and store the same, and may map feature information related to each component to assets and store the same. The asset may be data (e.g., a resource) for avatar generation. The mapping information 20 may be uploaded and/or updated by an operator of server 208 or a third party.

According to various embodiments, the electronic device 201 may identify whether the mapping information 20 is updated before constituting a face. For example, the electronic device 201 may transmit a version of the mapping information to the server 208 to identify whether the mapping information is updated and when an update is required, may download the mapping information 20 from the server 208 (indicated by reference numeral 221). According to an embodiment, the electronic device 201 may identify whether an asset needs to be added or changed in response to an update of the mapping table, and if necessary, may download the added or changed asset from the server 208 (indicated by reference numeral 223).

According to an embodiment, the electronic device 201 may perform body configuration based on feature information (e.g., race, age, skin color, and/or gender) (e.g., select a body base model mapped to feature information) extracted through face recognition. According to an embodiment, the electronic device 201 may perform body configuration based on a result of body recognition. According to another embodiment, the electronic device 201 may perform clothes configuration based on a result of face recognition and/or clothes recognition (e.g., select a clothes asset mapped to the recognition result).

According to various embodiments, the electronic device 201 may model an avatar by combining the configured face, body, and/or clothes, and may render the modeled avatar (indicated by reference numeral 230) to generate an avatar (e.g., a three-dimensional avatar).

According to various embodiments, the server 208 may manage the mapping information 20. For example, the server 208 may provide the electronic device 201 with the mapping information 20 uploaded and/or updated by an operator or a third party. According to an embodiment, the server 208 may provide the mapping information 20 by reflecting the characteristics of a user of the electronic device 201. For example, the server 208 may receive information regarding the user's characteristics (e.g., country information, a model name of the electronic device, event information, user account information, and/or avatar generation history information) from the electronic device 201, and may provide mapping information corresponding to the received information to the electronic device 201.

The system 200 according to an example embodiment described above may update only the mapping information 20 through the server 208, instead of updating the entire configuration to satisfy compatibility between the entire elements included in the electronic device 201 (e.g., the recognition module 231, the generation module 233, and the rendering module 235), so as to update the avatar generation function easily and quickly. In addition, the system 200 may provide a personalized (e.g., more suitable for a user) avatar generation function by providing the mapping information 20 by reflecting the user's characteristic information.

FIG. 3A is a block diagram of an electronic device according to an example embodiment, FIG. 3B illustrates an example of updating a mapping table according to an example embodiment, and FIG. 3C illustrates another example of updating a mapping table according to an example embodiment.

Referring to FIGS. 3A to 3C, an electronic device 301 (e.g., the electronic device 101 of FIG. 1, the electronic device 201 of FIG. 2) according to an example embodiment may include a camera 380 (e.g., the camera module 180 of FIG. 1), a memory 330 (e.g., the memory 130 of FIG. 1), a display 360 (e.g., the display module 160 of FIG. 1), a processor 320 (e.g., the processor 120 of FIG. 1), or a communication module 390 (e.g., the communication module 190 of FIG. 1).

According to various embodiments, the camera 380 may capture an image of a subject (e.g., a user). For example, the camera 380 may be activated when an avatar generation function or a camera function is executed to capture an image of subject in response to a user input. The image acquired through the camera 380 may be displayed as a preview image on the display 360, or may be captured and stored in the memory 330. The preview image or the image stored in the memory 330 may be analyzed (e.g., face recognition, body recognition, and/or clothes recognition) by the processor 320 to generate an avatar.

According to various embodiments, the memory 330 may store an image (e.g., a photo). The image stored in the memory 330 may be analyzed (e.g., face recognition, body recognition, and/or clothes recognition) by the processor 320 to generate an avatar. According to an embodiment, the memory 330 may store mapping information 30 (e.g., the mapping information 20 of FIG. 2). Since the mapping information 30 is similar to the mapping information 20 of FIG. 2, a detailed description thereof will be omitted.

According to various embodiments, the display 360 may display an image including an object (e.g., a person, an animal, a plant, and/or a thing) for avatar generation. In addition, the display 360 may display an avatar generated through an avatar generation function (or application).

According to various embodiments, the processor 320 may control avatar generation. For example, the processor 320 may recognize an object (e.g., a person) from the image displayed on the display 360, configure the face, body, and/or clothes of an avatar based on a result of the recognition, and combine the face, body, and/or clothes and then render the same to generate an avatar. According to an embodiment, the processor 320 may include a recognition module 321, a generation module (or a configuration module) 323, and a rendering module 325.

According to various embodiments, the recognition module 321 may include an image processing module 321-1 and a face recognition module 321-2. The image processing module 321-1 may process the image displayed on the display 360 (e.g., detect a face region) and transmit the processed image to the face recognition module 321-2. The face recognition module 321-2 may recognize a face from the image processed by the image processing module 321-1. For example, the face recognition module 321-2 may extract feature information of the face region and feature information of each component constituting the face. According to an embodiment, the recognition module 321 may further include a body recognition module for extracting (recognizing) body feature information. According to another embodiment, the recognition module 321 may further include a clothes recognition module for recognizing clothes.

According to various embodiments, the generation module 323 may configure (generate) the face, body, and/or clothes of the avatar based on a result of the recognition of the recognition module 321. According to an embodiment, the generation module 323 may include a face base generation module 323-1, a facial component generation module 323-2, a body base generation module 323-3, and a clothes generation module 323-4.

According to various embodiments, the face base generation module 323-1 may generate a face base model based on the feature information (e.g., race, age, gender, and/or skin color) recognized by the recognition module 321. According to an embodiment, the face base generation module 323-1 may select a face base model mapped to the feature information recognized by the recognition module 321, based on the mapping information 30.

According to various embodiments, the facial component generation module 323-2 may generate a facial component based on the feature information of each component (e.g., hairstyle, eyebrows, eyes, nose, mouth, beard, and/or accessories) recognized by the recognition module 321. According to an embodiment, the facial component generation module 323-2 may select an asset mapped to the feature information of each recognized component, based on the mapping information 30.

According to various embodiments, the body base generation module 323-3 may generate (e.g., select) a body base model based on the feature information (e.g., age, gender, and/or race) recognized by the recognition module 321. According to an embodiment, the body base generation module 323-3 may, based on the mapping information 30, generate (e.g., select) a body base model mapped to body feature information (e.g., slim, fat, belly, broad shoulders, and/or narrow shoulders).

According to various embodiments, the clothes generation module 323-4 may generate clothes based on feature information of an object (e.g., a person) recognized by the recognition module 321. For example, the clothes generation module 323-4 may select a clothes asset based on the recognized user's age, gender, and/or race. According to an embodiment, the clothes generation module 323-4 may select a clothes asset based on the user's clothes taste and/or event (e.g., birthday, Halloween, Christmas). The clothes generation module 323-4 may analyze the photos registered in the user's social network periodically or aperiodically (e.g., upon the user's request) to identify the user's clothes taste. According to another embodiment, the clothes generation module 323-4 may select a clothes asset based on the type of clothes recognized by the recognition module 231.

According to various embodiments, the generation module 323 may identify whether the mapping information 30 is updated before generating a face part of an avatar (e.g., including a face base and facial components). For example, the generation module 323 may transmit, to a server (e.g., the server 108 in FIG. 1, the server 208 in FIG. 2), a version of a mapping table included in the mapping information 30 before generating the face part of the avatar, so as to identify whether the mapping table is updated. If an update is required as a result of the identification, the generation module 323 may download an updated mapping table from the server. For example, as shown in FIG. 3B, the generation module 323 may download an updated mapping table 31b from the server and update a mapping table 31a related to the hairstyle. Referring to the mapping tables 31a and 31b of FIG. 3B, in the case of a second hair style (long hair, straight) and a third hair style (long hair, curl), it may be seen that the second and the third hair styles have been mapped to a first asset before the update of mapping table, but the second hairstyle is mapped to the first asset and the third hairstyle is mapped to a new first asset after the update of mapping table. Similarly, in the case of a 4th hairstyle (curly, short) and a 6th hairstyle (straight, short), it may be seen that the 4th and 6th hairstyles have been mapped to a second asset before the update, but the fourth hairstyle is mapped to the second asset and the sixth hairstyle is mapped to a new second asset after the update. In other words, it may be seen that the assets for the third hairstyle and the sixth hairstyle have been added. As another example, in the case of an N-th hairstyle (middle), it may be seen that the N-th hairstyle has been mapped to an N-th asset before the update, but the N-th hairstyle is mapped to a new N-th asset after the update. In other words, it may be seen that the asset for the N-th hairstyle has been changed.

According to various embodiments, the generation module 323 may download the updated mapping table 31b and identify whether an asset needs to be downloaded based on the downloaded mapping table 31b. For example, as shown in FIG. 3C, the generation module 323 may identify whether added assets (e.g., new first asset and new second asset) or changed assets (e.g., new N-th asset) exist in the memory 330 and when the added asset or changed asset does not exist, may download the added or changed asset from a server (indicated by reference numeral 32). According to an embodiment, the electronic device 301 may not include the mapping table 31a, and the mapping table 31b may be stored in the server. The generation module 323 may transmit facial feature information and feature information of each component to the server, and may download a face base model and/or each asset corresponding to the feature information of a face and/or feature information of each component from the server.

Meanwhile, although FIGS. 3B and 3C have described the operation of updating the mapping table 31a of the electronic device 301 by using a hairstyle as an example, the mapping table 31a may include a face base model and other facial components (e.g., eyebrows, eyes, nose, mouth, ears, or accessories), and update the face base model and other facial components in a manner similar or identical to a hairstyle.

According to an embodiment, the generation module 323 may further transmit information regarding a user (hereinafter, referred to as characteristic information) to the server and receive mapping information 30 corresponding to the characteristic information. The characteristic information may include terminal information (e.g., a model name), country information, event information, avatar generation history information, and/or user account information. Accordingly, the electronic device 301 according to an example embodiment may provide mapping information more suitable for a user (e.g., provide a personalized avatar service) based on user characteristic information.

According to various embodiments, when the update of mapping information is completed or the mapping information does not need to be updated, the generation module 323 may model an avatar by combining a face part, a body part, and/or clothes.

According to various embodiments, the rendering module 325 may generate an avatar (e.g., a three-dimensional avatar) by rendering the avatar modeled by the generation module 323, and display the generated avatar on the display 360.

According to various embodiments, the communication module 390 may communicate with a server. For example, the communication module 390 may receive the mapping information 30 from the server. As another example, the communication module 390 may transmit the version of the mapping information 30 to the server. This transmission is to identify whether mapping information is updated. As another example, the communication module 390 may transmit user characteristic information (e.g., a country, a model name of an electronic device, avatar generation history information, account information, and an event) to the server, and may receive mapping information corresponding to the user characteristic information 30.

Meanwhile, in the above description, it has been described that the update of the mapping information 30 is performed when the avatar is generated by the generation module 323, but the update of the mapping information 30 is periodically or aperiodically performed by the processor 320 (or the avatar generation application). According to another example, the electronic device 301 may update the mapping information 30 based on reception of a notification notifying of the update of the mapping information 30 from the server.

Although, in FIG. 3, the recognition module 321, the generation module 323, and the rendering module 325 are illustrated and described as hardware-based modules included in the processor 320, at least a part of the recognition module 321, the generation module 323, and the rendering module 325 may be implemented as a software module stored in the memory 330. According to an embodiment, at least a part of the recognition module 321, the generation module 323, and the rendering module 325 may be included in the electronic device 301 as a separate hardware module. Similarly, the image processing module 321-1, the face recognition module 321-2, the face base generation module 323-1, the facial component generation module 323-2, the body base generation module 323-3, or the clothes generation module 323-4 may be implemented as a software module or hardware module. Hereinafter, the functions of the recognition module 321, the generation module 323, and the rendering module 325 will be described as operations of the processor 320.

FIG. 4 is a block diagram of a server according to an example embodiment.

Referring to FIG. 4, a server 408 (e.g., the server 108 of FIG. 1, the server 208 of FIG. 2) according to an example embodiment may include a communication module 410, a processor 420, and a memory 430.

According to various embodiments, the memory 430 may store mapping information 40. The mapping information 40 may include a mapping table (e.g., the mapping table 31b of FIG. 3B) and assets. The mapping information 40 may be uploaded and updated by an operator of a server 408 or a third party. The operator or the third party may upload and/or update the mapping information 40 to the memory 430 through a manager service.

According to various embodiments, the communication module 410 may communicate with an electronic device (e.g., the electronic device 101 of FIG. 1, the electronic device 201 of FIG. 2, and the electronic device 301 of FIG. 3). For example, the communication module 410 may transmit the mapping information 40 to the electronic device under the control of the processor 420. According to an embodiment, the communication module 410 may receive a version of mapping information (e.g., mapping information 30) and/or user characteristic information stored in the electronic device from the electronic device, and may transmit updated mapping information to the electronic device based on the received version and/or user characteristic information under the control of the processor 420.

According to various embodiments, the processor 420 may control the operation of the server 408. For example, the processor 420 may control the operation of the server 408 to provide management of the mapping information 40, a browsing service, and/or an asset download service to the electronic device. According to an embodiment, the processor 420 may include an asset providing module 421 and a mapping table providing module 423.

According to various embodiments, the asset providing module 421 may provide an added or changed asset to the electronic device through the communication module 410. For example, the asset providing module 421 may provide assets requested by the electronic device (e.g., an asset that does not exist in the electronic device) to the electronic device through the communication module 410. The asset may include an asset related to a face base, an asset related to a facial component, an asset related to a body base, and/or an asset related to clothes.

According to various embodiments, the mapping table providing module 423 may provide the mapping table to the electronic device through the communication module 410. For example, the mapping table providing module 423 may receive a version of the mapping table and/or a user's characteristic information from the electronic device, identify whether the mapping table needs to be updated based on the received version of the mapping table and/or the user's characteristic information and, when an update is required, transmit the updated mapping table to the electronic device.

According to various embodiments, the mapping table providing module 423 may remap a mapping table (e.g., change an asset mapped to each feature information of the mapping table) based on the user's characteristic information to provide a personalized mapping table to the electronic device. For example, the mapping table providing module 423 may remap the mapping table to an asset compatible with the electronic device based on a model name of the electronic device, so as to provide a personalized mapping table to the electronic device. As another example, the mapping table providing module 423 may remap the mapping table to an asset specific to a corresponding country based on country information, so as to provide the personalized mapping table to the electronic device. As another example, the mapping table providing module 423 may remap the mapping table to an event-specific asset based on event information (e.g., birthday, Halloween, or Christmas), so as to provide the personalized mapping table to the electronic device. As another example, the mapping table providing module 423 may remap the mapping table to the user's preferred asset based on the avatar generation history or user account information, so as to provide the personalized mapping table to the electronic device.

FIG. 5 is a flowchart illustrating a method for managing information for avatar generation by an electronic device according to an example embodiment.

Referring to FIG. 5, a processor (e.g., the processor 120 of FIG. 1, the processor 320 of FIG. 3A) of an electronic device (e.g., the electronic device 101 of FIG. 1, the electronic device 201 of FIG. 2, and the electronic device 301 of FIG. 3A) according to an example embodiment may detect an avatar generation request in operation 501. For example, the processor may be configured to detect execution of an avatar generation function (or application).

According to various embodiments, the processor (or the recognition module 321 of FIG. 3A) may recognize an image for avatar generation in operation 503. The image may be a preview image obtained through a camera (e.g., the camera module 180 of FIG. 1, the camera 380 of FIG. 3A) or an image which is loaded (or read) from a memory (e.g., the memory 130 of FIG. 1, the memory 330 of FIG. 3A) and displayed on a display (e.g., the display module 160 of FIG. 1, the display 360 of FIG. 3A). Avatar generation may be requested in a state in which an image is displayed. According to an embodiment, the processor may be configured to activate a camera in response to a request for avatar generation to obtain a preview image, or load an image selected by a user from among images stored in the memory and display the image on the display.

According to an embodiment, the processor may be configured to recognize an object (e.g., a person) for avatar generation from an image, and may recognize (extract) feature information of a face of the recognized object and feature information related to each component configuring the face (e.g., hair style, eyebrows, eyes, nose, mouth, beard, or accessories). The feature information of the face may include skin color, race, gender, age, or appearance (e.g., oval, square, or round). Feature information related to the hairstyle may include curly hair, long hair, short hair, medium hair, straight, or wavy hair, and feature information related to eyebrows includes straight eyebrows, thin eyebrows, thick eyebrows, and sagging eyebrows. Feature information related to eyes may include double eyelids, single eyelids, and drooping eyes, and feature information related to nose may include a low nose, a broad nose, a short nose, and a long nose. Feature information related to a mouth may include a protruding mouth, a small mouth, and a large mouth, feature information related to a beard may include no beard, a mustache, a beard, a long beard, and a short beard, and the accessory may include glasses, earrings, a nose ring, and a color lens. The feature information related to each component described above is only an example and does not limit the disclosure.

According to an embodiment, the processor may be configured to recognize (extract) feature information related to the body and/or clothes of an object included in an image.

According to various embodiments, in operation 505, the processor (or the generation module 323 of FIG. 3A) may identify whether mapping information (e.g., the mapping information 20 of FIG. 2, the mapping information 30 of FIG. 3A) needs to be updated. For example, the processor may be configured to transmit the version of a mapping table (e.g., the mapping table 31a in FIG. 3B) to a designated server (e.g., the server 208 in FIG. 1, server 208 in FIG. 2, the server 408 in FIG. 4).) to identify whether the mapping table is updated.

In case that the update is not required as a result of the identification of operation 505, the processor may be configured to proceed to operation 511, which will be described later. On the other hand, when the update is required as a result of identification of operation 505, the processor may be configured to transmit user characteristic information to a designated server in operation 507. The user characteristic information may include a model name of the electronic device, country information, event information, avatar generation history information, and/or user account information.

According to various embodiments, the processor (or the generation module 323 of FIG. 3A) may receive mapping information corresponding to the user's characteristic information from the server in operation 509. For example, the processor may be configured to receive the latest mapping table from the server and update the mapping table stored in the memory. In addition, the processor may be configured to identify whether an asset to be downloaded exists based on the updated mapping table, and in case that there is an asset to be downloaded, the processor may be configured to download and store the asset from the server.

According to various embodiments, the processor (e.g., the generation module 323 and the rendering module 325 of FIG. 3A) may generate an avatar based on the image recognition result and mapping information in operation 511. For example, the processor (e.g., the generation module 323 of FIG. 3A) may select a face base based on facial feature information, select an asset corresponding to each component based on the feature information of each component, and configure the face part by arranging the selected asset on the selected face base. Similarly, the processor (e.g., the generation module 323 of FIG. 3A) may configure body parts and/or clothes. The processor (e.g., the generation module 323 of FIG. 3A) may model the avatar by combining the configured face part, body part, and clothes. The processor (e.g., the rendering module 325 of FIG. 3A) may generate the avatar by rendering the modeled avatar.

According to an embodiment, the processor may be configured to identify whether the mapping information is updated periodically or aperiodically, even when the avatar is not generated. According to another embodiment, the processor may be configured to update the mapping information upon receiving an alarm notifying of the update of the mapping information from the server.

According to an embodiment, the mapping table may be stored in the server instead of being stored in the electronic device. In this case, operation 505 is omitted, and operation 507 may correspond to an operation in which the processor transmits feature information of a face and/or feature information of each component and the user's characteristic information to the server through the communication module. Operation 509 may correspond to an operation in which the processor receives a face base model and/or each asset from the server through the communication module. Operation 511 may be an operation of generating an avatar based on the received face base model and/or each asset.

FIG. 6 is a flowchart illustrating a method for managing information for avatar generation by a server according to an example embodiment.

Referring to FIG. 6, a processor (e.g., the processor 420 in FIG. 4) of a server (e.g., the server 108 of FIG. 1, the server 208 of FIG. 2, the server 408 of FIG. 4) according to an example embodiment may receive a version of a mapping table (e.g., the mapping table 31a of FIG. 3B) and/or user characteristic information from an electronic device (e.g., the electronic device 101 of FIG. 1, the electronic device 201 of FIG. 2, the electronic device 301 of FIG. 3A) through a communication module (e.g., the communication module 410 of FIG. 4) in operation 601. For example, the processor may be configured to receive version information of the mapping table and user characteristic information together through the communication module. As another example, when a mapping table reflecting user characteristics is not provided, the processor may be configured to receive a version of the mapping table included in the electronic device through the communication module. As another example, as described with reference to FIG. 5, after receiving the version of the mapping table, when an update of the mapping table is required, the processor may be configured to receive user characteristic information. As another example, after transmitting an alarm notifying of an update of the mapping table to the electronic device, the processor may be configured to receive user characteristic information through the communication module. Hereinafter, a case in which the processor receives both the version of the mapping table and the user's characteristic information will be described as an example.

According to various embodiments, in operation 603, the processor may be configured to identify whether the mapping table has been updated. For example, the processor may be configured to compare a version of a mapping table (e.g., the mapping table 31b of FIG. 3B) stored in a memory (e.g., the memory 430 of FIG. 4) with a version of a received mapping table (e.g., the mapping table 31a of FIG. 3B), so as to identify whether the mapping table has been updated.

As a result of the identification of operation 603, in case that the mapping table is not updated, the processor may be configured to end a mapping table update procedure. According to an embodiment, the processor may be configured to transmit a response indicating that the update is unnecessary to the electronic device through the communication module.

As a result of the identification of operation 603, in case that the mapping table is updated, the processor may be configured to transmit the updated mapping table to the electronic device in operation 605. The updated mapping table may be updated (or remapped) by reflecting user characteristic information.

According to various embodiments, in operation 607, the processor may be configured to identify whether an asset download is requested. The asset requested to be downloaded may be an asset that is added or changed due to an update of the mapping table and does not exist in the electronic device.

As a result of the identification of operation 607, in case that the download of the asset is not requested, the processor may be configured to end the mapping table update procedure. As a result of the identification of operation 607, when a download of an asset is requested, the processor may be configured to transmit the requested asset to the electronic device in operation 609.

According to an embodiment, the mapping table may be stored in the server instead of being stored in the electronic device. In this case, operations 601 and 603 may correspond to an operation of receiving feature information of a face and/or feature information of each component and the user's characteristic information from the electronic device. Operation 605 may correspond to an operation of transmitting information related to the face base model and/or each asset selected based on the received feature information and/or the characteristic information. The electronic device may identify whether at least one asset that needs to be downloaded (e.g., an asset that is not stored in the electronic device) exists based on the information, and may request a server to download the at least one asset that needs to be downloaded.

According to various example embodiments, an electronic device (e.g., the electronic device 101 of FIG. 1, the electronic device 201 of FIG. 2, and the electronic device 301 of FIG. 3A) may include a communication module (e.g., the communication module 190 of FIG. 1, the communication module 390 of FIG. 3A), a display (e.g., the display module 160 of FIG. 1, the display 360 of FIG. 3A), a memory (e.g., the memory 130 of FIG. 1, the memory 330 of FIG. 3A) configured to store mapping information (e.g., the mapping information 20 of FIG. 2, the mapping information 30 of FIG. 3A) for avatar generation, and at least one processor (e.g., processor 120 of FIG. 1, processor 320 of FIG. 3A) operatively connected, directly or indirectly, to the communication module, the display, and the memory, wherein the at least one processor is configured to, in response to an avatar generation request, recognize an image displayed on the display, and generate an avatar based on a result of the recognition of the image and the mapping information, and wherein the at least one processor is configured to, in case that the mapping information needs to be updated, transmit characteristic information regarding a user of the electronic device to a designated server (e.g., the server
