Abstract
The present invention is directed to provide a solid-state imaging apparatus and a method of driving the solid-state imaging apparatus. If the total read out time of all of the pixels is shortened when effective pixels are thinned out to be read out without thinning out OB pixels, then the reset time period of each row is different from each other, and the problem of uneven charge accumulation time periods is caused. An improvement by the present invention is that, if no signals are read out from a part of the rows of the pixels in an effective pixel region to skip the rows, then the time period in which the rows to be skipped are selected is made to be shorter than the time period in which the rows from which signals are read out are selected, and the pixels in the optical black pixel region and the pixels in the effective pixel region are driven by the drive pulses of patterns different from each other.
