I though the green in the bayer-filter was over-represented because the human eye is more sensitive to green compared to other colours?

- Syzygies 3y agoExactly. It's the best proxy for grayscale detail. One could have balanced RGB in a hexagonal grid. That's harder to build and slower to process. He would have considered a hex grid, but our rectilinear cognitive bias was pretty entrenched. Before this work, he programmed an entire image processing system in the "ed" PDP editor, manipulating character arrays. That experience influenced both the Bayer filter and Bayer dithering. And it taught me to look for simple ways to do things.
