The sensor will have a Bayer pattern [1] and the data will go across the bus in Bayer format. The processor will then perform debayering. So no need to multiply by 3 channels per pixel :)
While many image sensors will perform debayering for you if you want, doing so means you need 3x the bandwidth for not much benefit, so very few people do it.

- jandrese 5y agoSo you are working in monochrome? Even after you have applied the Bayer filter you still need 24 bits per pixel do you not?
- michaelt 5y agoNo - go check out that Wikipedia link about Bayer filters. For the vast majority of cameras, if you buy a "4 megapixel" image sensor, you get 1 million red pixels, 2 million green pixels, and 1 million blue pixels. When you load the image into your image editor and see 3 colours per pixel, 2 of the 3 are interpolated from neighbouring pixels.
