ABSTRACT:
An image sensor includes a plurality of photosensitive pixel lines adjacent to each other in the sub-scanning direction, each of the photosensitive pixel lines having a number of photosensitive pixels arranged in the main scanning direction, and horizontal transfer registers disposed outside of the photosensitive pixel lines. A storage part for saving therein signal charges on a pixel-by-pixel basis is interposed between the photosensitive pixel lines and the horizontal transfer registers. Transfer of signal charges between the photosensitive pixel lines, storage part, and horizontal transfer registers are controlled by operating shift gates so that at a time point when exposure of the inside photosensitive pixel line has been finished, signal charges of the outside photosensitive pixel line is saved into the storage part to thereby secure a transfer passage for signal charges of the inside photosensitive pixel line.
