Imaging device, imaging system, and method for driving imaging device for capturing an image with a restrained influence of a blinking state of a light source

There is provided an imaging device configured to acquire an image with the restrained influence of the blinking state of a light source while ensuring synchronicity of charge accumulation. For a plurality of pixels arranged in a plurality of rows, the imaging device intermittently turns on a first transfer switch at a same timing a plurality of times to transfer electric charges from a photoelectric conversion unit to a holding unit a plurality of times. The imaging device row-sequentially turns on a second transfer switch of the plurality of pixels to transfer electric charges transferred a plurality of times to and held by the holding unit, to an amplifying unit on a row basis.
