A solid-state imaging apparatus includes: a pixel unit (1) configured to perform imaging of a plurality of frames by a photoelectric conversion; an exposure amount calculating unit (9) configured to calculate exposure amounts of the plurality of frames imaged in a flicker cycle of a light source; and a control unit (12) configured to control the exposure amount of each of the frames imaged by the pixel unit based on the exposure amounts of the plurality of frames calculated by the exposure amount calculating unit.
