PROBLEM TO BE SOLVED: To shorten signal processing time by providing the color filter of M rows×N columns, for which the two unit arrays of 2×2 for which first and second colors and first and third colors are arrayed in a checkered pattern, are arrayed in the checkered pattern. SOLUTION: At the upper part of an image pickup area 17, where sensor parts 11 are arrayed in a two-dimensional matrix, the color filter of prescribed color coding is formed by allocating one color to a sensor part 11. That is, it is turned to the color filter of the color coding of M rows×N columns, for which the unit arrays of 2×2 for which green and red and green and blue are respectively arrayed in the checkered pattern are arrayed in a checkered pattern. Then, at signal charge transfer from a vertical CCD to a horizontal CCD, the two pixels of the same color are added obliquely. A unit charge, for which the signal charge of the obliquely added two pixels is a unit, is transferred horizontally in the horizontal CCD 14, converted to a voltage in a charge detection part 15 and then outputted from an output circuit 16. This is repeated for every two rows. Thus, addition signals are considered as signals from two image pickup element, the interpolation processing of only two colors is sufficient, and processing time is shortened.
