It seems the camera sensor world could be getting very interesting here in the near future. A new patent from Canon shows off an exciting new 5 layer sensor that includes UV, RGB, and IR layers.
The most similar technology currently available is likely the Foveon sensor from Sigma, which includes 3 layers. That technology is currently only seen in Sigma’s DP line of cameras. There have been rumors before that Canon was looking to produce a sensor similar to the Foveon, but until today, all of those rumors talked about Canon working on “just” a 3 layer sensor.
This new design from Canon, as mentioned, features UV and IR layers, in addition to the RGB layers. According to the rumor, the UV and IR layers are used for better color reproduction, specifically the color reproduction of skin tones.

Overall, it looks like some interesting tech, and would appear to be a fairly unique sensor. The rumored 7D Mark II is supposed to be coming with some sort of revolutionary new sensor tech, and while the latest rumors say that tech will not be Foveon like, it is still possible that this could be what is featured on the upcoming camera.
