Abstract
A semiconductor device includes a pixel array including a plurality of pixels arranged in a matrix, each pixel including a first switch and a second switch, a scanning circuit, in a first mode, enabling a first signal to be output from the pixel by setting the first and second switches to 'off' in a period before a first timing, enabling a second signal to be output from the pixel by setting only the first switch to 'on' for a predetermined period from the first timing, and enabling a third signal to be output from the pixel by setting the first and second switches to “on” for a predetermined period from a second timing after the first timing, and a first AD (Analog/Digital) converter, in a second mode, capable of performing AD conversion by comparing the difference between the second signal and the first signal with a reference signal.
