I did a little bit of research on filters that go in front of image sensors. It's a Bayer filter and it is 1/2 green, 1/4 red, and 1/4 blue. This has the effect of band-passing the frequencies of those colors at the corresponding photo sites. It then reads the voltage values at those photo sites. Combining these values into colored pixels is called "demosaicing." I imagine a lot of the same considerations come into this process as the sampling procedures in assignment 1.

It is interesting how each sensor only takes on one hue (red, green, or blue), instead of all three. On this slide, it appears that there is exactly one sensor per pixel. Is this always the case? Can one pixel be mapped to multiple sensors?
