What do people want to see in the Canon EOS R1? PetaPixel gives their thoughts

[Michael Clark]

The phones are using quad Bayer arrays and extracting hi-res images (in spite of the tiny pixels), so it seems that a full decoded 45MP QPAF sensor would produce a similar increase (i.e. 180MP) in resolution with larger pixels. The resulting color resolution would probably be much like video with 4:2:0 coding, but that is the standard for a majority of video. At this point, LR classic even knows how to manage a 48MP RAW from the new iPhones, so not a huge stretch to see something similar on a Canon. The 3x3 shift in the high res mode recently introduced to the R5 also suggests that Canon my be exploring that path, since that shift pattern is very different from what others have been doing for high res modes.

To begin, the colors of typical CFAs are not the same colors emitted by our RGB screens, nor are they the same colors used by our CMYK printers. Further, the filters in a CFA are not so strong as to eliminate all but a narrow band of wavelengths from passing through. There's a lot of overlap between what is allowed to pass through the three different filters, just as there is a lot of overlap between our S-cones, M-cones, and L-cones to various wavelengths. If there was not this overlap, we couldn't use the results from our cameras to mimic the brain and create the perception of color.
