A solid-state imaging device comprises, on a semiconductor substrate, a plurality of sensor sections for storing a signal charge commensurate with a quantity of reception light, a charge transfer section for transferring and outputting the signal charge of the sensor sections, and an output section for converting the signal charge transferred by the charge transfer section into an imaging signal for output. A current controller is provided to cut off or reduce a current flowing to the output section in a signal storage period of the sensor section. This cuts off or reduces the current flowing to the output section in a signal storage period of the sensor section, and hence suppresses the amount of the current flowing to the output section in the signal storage period. Thus, wasteful consumption power is greatly reduced.
