Solid-state imaging apparatus

A solid-state imaging apparatus includes a plurality of pixels, each pixel including: a photoelectric conversion unit; an amplification element; a first signal holding unit and a second signal holding unit arranged on an electric pathway between the photoelectric conversion unit and an input node of the amplification element; a first electric charge transfer unit configured to transfer an electron of the photoelectric conversion unit to the first signal holding unit; and a second electric charge transfer unit configured to transfer an electron held by the first signal holding unit to the second signal holding unit, wherein a voltage supplied to a first control electrode when the electron of the photoelectric conversion unit is transferred to the first signal holding unit is lower than a voltage supplied to a second control electrode when the electron held by the first signal holding unit is transferred to the second signal holding unit.
