ABSTRACT:
A solid-state image pickup device, and in particular, a CCD image sensor is capable of color reading, wherein n lines (n.gtoreq.2) of photo diodes disposing a plurality of photodiodes straightly are disposed parallel adjacently to each other, and adjacent n lines of CCD analog shift registers are disposed parallel to the photodiode lines at one side of the group of n lines of photodiodes, and the signal charges are transferred through a gate structure composed of MOS structure, between adjacent lines of n lines of photodiodes and n lines of CCD analog shift registers. It is therefore possible to reduce the intervals of the photodiode lines to the limit, thereby realizing a CCD color linear image sensor capable of outstandingly simplifying the signal time axis correction circuit such as semiconductor digital memory device for correcting the differences of reading positions of the photodiode lines.
