A solid-state imaging device includes a plurality of pixels each including a photoelectric conversion unit, a charge accumulating portion accumulating signal charges transferred from the photoelectric conversion unit, a floating diffusion portion accumulating signal charges transferred from the charge accumulating portion, and a read-out unit transferring signal charges from the charge accumulating portion to the floating diffusion portion and output a signal corresponding to the signal charges, and a control unit controlling the read-out unit to start, after starting read-out of signals of one frame from the charge accumulating portions, an accumulation of signal charges for a next frame at the photoelectric conversion units simultaneously, and to start, before completing the read-out of the signal of the one frame, an accumulation of signal charges at the charge accumulating portion of a pixel among the plurality of pixels from which the signal of the one frame is already read out.
