Abstract
To increase a readout speed of a pixel signal in a non-differential mode in a solid-state image sensor that performs differential amplification in a differential mode and does not perform differential amplification in the non-differential mode. A connection control unit sequentially performs control of connecting a first pixel connected to a first signal line to a reset power supply via a third signal line and control of connecting a second pixel connected to a second signal line to the reset power supply via a fourth signal line in a differential mode, and performs control of connecting a third pixel to the third signal line and control of connecting the fourth pixel to the fourth signal line in a non-differential mode. Furthermore, a drive unit outputs a signal obtained by amplifying a difference between respective pixel signals of the first and second pixels via one of the first and second signal lines in the differential mode, and outputs respective pixel signals of the first, second, third, and fourth pixels via the first, second, third, and fourth signal lines in the non-differential mode.
