Abstract
A color filter arrangement () is used, in which a plurality of filter units are each made of 2×2 arrangements of red (R), green (G), green (G) and blue (B) color elements. First, signal charges are added up for all pixels belonging to each of a plurality of pixel blocks made of quadratic arrangements of 3×3 of pixels, which are larger than the filter units (2×2 arrangement). Then, compressed color information for each of the pixel blocks is obtained from a result of the addition for each pixel block, taking the 2×2 arrangements of pixel blocks as large filter units.
