"This structure enables all color information of red, green and blue to be obtained within a single pixel, achieving a high-resolution image sensor that uses light more efficiently. We will continue to work reducing the pixel size and increasing the number of pixels, and accelerate R&D toward realizing a compact, high-resolution, single-chip camera."
While appreciating full color representation(R,G,B) for each pixel, it comes the concerns of wider(ex. 30-bit, if 10-bit ADC) pipeline bus for image data and processing, which essentially means bigger area/higher power consumption, as well as more bandwidth for image output.
ReplyDeleteMany people have spent a lot of money and time, but the image quality is still this level.
ReplyDeleteWhat is the motivation to develop organic sensors?
As far as I know, blue, green, and red typical layers filter their own light components. Thus, if we stack them, theoretically no electron will reach the substrate.
ReplyDeleteMaybe I'm missing something very obvious, but how is the color image rebuilt?
I believe probability of photon absorption at a specific wavelength (green), does not preclude the transmission of longer (red) light, that's also why blue is on top, then green and then red as the deeper penetrating wavelength is last.
DeleteThis is the same problem as how a colour film is made by the way.
DeleteIt seems like Foveon image sensor of SIGMA.
