Sony's multi-layer sensor patents drive image development

Sony has announced a number of multi-layer sensor patents, similar to Sigma's foveon sensor, which separates the photosensitive layers of the three primary colors, but the difference is that Sony is still trying more photosensitive materials and arrays. The three patents of this time all adopt the three-layer overall layout, the difference is that the first one is green-blue-red order, in which the green photosensitive layer uses organic materials; the second one is similar to the first one, just green The blue layer is made of organic materials; the third one is somewhat complicated. The top is yellow and cyan photosensitive layer, the middle is organic layer of green material, and the lower layer is red and purple. As for which one will become the winner in the end, it is not easy to say, after all, it depends on the progress of research and development.

Edit Comment: Multi-layer sensors can get rid of many imaging problems of "mosaic" sensors, such as pseudo-color, moiré, etc. At present, the biggest problem that foveon sensor needs to solve is high sense and power consumption. Sony's various programs should be in Find the best combination. In addition, Sony's multi-layer sensor patent also incorporates organic sensors. It is known that the development of organic sensors has encountered some bottlenecks, which will add many obstacles to the final molding of Sony patents. However, from the perspective of development, if there is a major breakthrough in research and development, it will certainly play a big role in promoting the development of images.
