IMAGING DEVICE AND SIGNAL PROCESSING METHOD THEREFOR

摘要

Each of a plurality of filter units uses a color filter array (11) consisting of a 2x2 array of color elements, red (R), green (G), green (G) and blue (B). In addition, within a plurality of pixel blocks each consisting of a 3x3 pixel normal array larger than each filter unit (2x2 array), the signal charges of all the pixels belonging to each of the applicable pixel blocks are added up. Then, condensed color information for each pixel block is obtained from the result of the addition for each pixel block, using the 2x2 array of a pixel block as a large filter unit.
