Abstract
A solid-state imaging device for preventing aging deterioration of image quality due to a thinning out reading mode in addition to a usual all pixel reading operation mode and maintaining a good image quality and a method for driving the same, including an imaging pixel portion 111 formed by arranging a plurality of pixels each including a photo-electric conversion element and a reading circuit of the photo-electric conversion element in a matrix, having an all pixel reading mode for reading pixel signals from all pixels of the imaging pixel portion 111 and a thinning out reading mode for intermittently selecting part of the pixels of the imaging pixel portion 111 for each pixel row or each pixel column or both of them to read out pixel signals, and having drive circuits 112 to 116 having a function of selecting the reading circuit of the imaging pixel portion 111 for each pixel row or each pixel column by a drive signal and receiving as input drive signals also with respect to the pixel rows or pixel columns thinned out at the time of driving by the thinning out reading mode to operate the reading circuit of each pixel.
