According to one embodiment, in a pixel array unit, pixels that accumulate photoelectrically converted charges are arranged in a matrix shape. A vertical signal line transmits a signal read out from the pixels in the vertical direction. An acceleration circuit shifts the potential of the vertical signal line in advance before a signal is read out from the pixels. The acceleration control circuit controls timing for shifting the potential of the vertical signal line in advance. The timing control circuit generates a control signal for controlling the acceleration control circuit. |
