1. A solid-state imaging device comprising:
a pixel array unit in which pixels storing electric charge acquired through a photoelectric conversion are arranged in a matrix pattern; a vertical signal line that transmits pixel signals read out from the pixels in a vertical direction; a vertical selection circuit that sets an electronic shutter state and a read-out state for each selected row of the pixel array unit in time division multiplex; a pulse selector circuit that drives the pixels belonging to the selected row in accordance with the electronic shutter state and the read-out state; and a timing generator circuit that controls operational timing of the vertical selection circuit and the pulse selector circuit, wherein the vertical selection circuit includes: a comparator that is used commonly in the electronic shutter state and the read-out state and compares a row selection value and a row number; and a register that is used commonly in the electronic shutter state and the read-out state and holds a comparison result of the comparator, and wherein the vertical selection circuit performs time division multiplexing of a period in which the electronic shutter state is set and a period in which the read-out state is set.
