PROBLEM TO BE SOLVED: To provide an imaging apparatus that is able to obtain a correction signal for a false signal.SOLUTION: An imaging apparatus has a plurality of pixels, each having: a photoelectric conversion part that accumulates electric charges generated by incident light; a first holding part and a second holding part that hold electric charges; an amplifying part that outputs a signal based on electric charges; a first transfer switch provided between the photoelectric conversion part and the first holding part; a second transfer switch provided between the photoelectric conversion part and a second holding part; a third transfer switch provided between the first holding part and the amplifying part; and a fourth transfer switch provided between the second holding part and the amplifying part. The imaging apparatus outputs a signal including a signal based on an actual-signal electric charge, and a signal including a signal based on a false-signal electric charge.SELECTED DRAWING: Figure 2 【課題】偽信号の補正用信号を取得し得る撮像装置を提供する。【解決手段】入射光によって生じた電荷の蓄積を行う光電変換部と、電荷を保持する第１保持部及び第２保持部と、電荷に基づく信号を出力する増幅部と、光電変換部と第１保持部の間に設けられた第１転送スイッチと、光電変換部と第２保持部の間に設けられた第２転送スイッチと、第１保持部と増幅部の間に設けられた第３転送スイッチと、第２保持部と増幅部の間に設けられた第４転送スイッチと、を各々が有する複数の画素を有し、実信号電荷に基づく信号を含む信号と、偽信号電荷に基づく信号を含む信号とを出力する。【選択図】図２
