Abstract
Abstract A solid-state imaging system is provided with a vertical and/or horizontal window function, in which vertical and/or horizontal scanning corresponding to an unnecessary pick-up range of a camera subject (hatched portions of FIG. 8) is done with a high rate or omitted by driving with high frequency or resetting a vertical and/or a horizontal scanning register.
