Lens-sensor Resolution Calculations Made Easy
Pete wrote:
I took the Bayer CFA into account, as was done in my references. Also of interest was a measured value from a 10 MP Canon showing it needed 2.72 pixels to resolve a line pair - a multiplying factor of 1.36, which implies it requires 15 MP to resolve 8 MP, as you suggested. Which fits in quite well with the 'distance of green pixels to their nearest green neighbour' == SQRT(2) ~= 1.4 pixels, indicating that green pixels carry most of the resolving power. -Wolfgang |
