i did not dispute interpolation.

interpolation yes, spatial no. there are n pixels going in, n pixels
coming out.

no. bayer is a *lot* more complicated than that.

What makes you think I am? A Bayer camera described as, for example,
12MP, typically has 3MP of red, 3MP of blue, and 6MP of green sensitive
elements, from which a 12MP RGB output image is derived.

It is spatial. Typically there are n red sensing pixels, but 4n RGB
output pixels.
