SONY is proposing a sci-fi technology in its new published patent

Single Shot HDR: Exciting Sony Patent Describes Image Sensor with Per-Pixel Exposure

Imagine an image sensor that can expose different parts of an image differently, not by using multiple shots and blending them intelligently, but all at once on a per-pixel basis. Seem like science fiction? We thought so too, but that’s exactly what Sony is proposing in a recent patent. Dug up by one of the posters on SonyAlphaForum, the patent was filed in July and published on October 30th. It shows a sensor that can expose individual pixels differently depending on where the darker parts and lighter parts of the scene are. So dark shadows would become ‘long exposure pixels’ while bright highlights would become ‘short exposure pixels,’ essentially spitting out a high dynamic range image without the need to take multiple exposures and combine them.
