ABSTRACT:
A CCD image sensor having a plurality of VCCDs each formed in a zig-zag pattern in a vertical direction and a plurality of groups of first to fourth photodiodes, the first to fourth photodiodes of the respective groups being arranged respectively on the left and right sides of each of the VCCDs, so that an improvement in resolution of a picture can be made in the same chip size. The first photodiodes are arranged on the left sides of curved portions of each of the VCCD regions on odd horizontal scanning lines, the second photodiodes are arranged on the right sides of the curved portions of each of the VCCD regions on even horizontal scanning lines, the third photodiodes are arranged on the right sides of the curved portions of each of the VCCD regions on the odd horizontal scanning lines, and the fourth photodiodes are arranged on the left sides of the curved portions of each of the VCCD regions on the even horizontal scanning lines. The third photodiodes and the fourth photodiodes are lined up in a straight line in the vertical direction.
