Abstract
A solid-state image sensor includes a pixel array section including a plurality of unit pixels each having a photoelectric conversion unit, the plurality of unit pixels being arranged in a matrix, a constant current source circuit unit having a constant current source connected to each of vertical signal lines provided in association with column arrangement of the pixel array section; and a control unit configured to control the constant current source circuit unit. The constant current source includes a plurality of transistors. The control unit switches, in a case where the plurality of transistors constituting the constant current source is regarded as one transistor having a gate width and a gate length being equivalent to each other, a ratio between the gate width and the gate length of the plurality of transistors on the basis of illumination in image-capturing environment.
