PROBLEM TO BE SOLVED: To provide an imaging apparatus that is able to pick up a high image quality video that is accumulated for a long period, without increasing a pixel size, and to provide a control method for an imaging apparatus.SOLUTION: An imaging apparatus comprises a plurality of pixels arranged in columns and rows, each pixel having: a photoelectric conversion part that accumulates signal charges generated by photoelectric conversion of emitted light; a first holding part and a second holding part, each of which holds a signal charge transferred from the photoelectric conversion part; and an output part that outputs a signal to a row signal line, the signal being based on an amount of signal charges held by the first holding part or second holding part. The first holding part and second holding part alternately hold, for each frame period, the signal charge generated in the photoelectric conversion part, and output a signal charge to the output part in a period for which a single charge is not transferred from the photoelectric conversion part.SELECTED DRAWING: Figure 2 【課題】画素サイズを大きくすることなく、蓄積期間の長い高画質な映像を撮像できる撮像装置、撮像装置の制御方法を得る。【解決手段】照射された光を光電変換して生じた信号電荷を蓄積する光電変換部と、光電変換部から転送される信号電荷を保持する第１保持部及び第２保持部と、第１保持部又は第２保持部が保持する信号電荷の電荷量に基づく信号を列信号線に出力する出力部と、を有する行列状に配された複数の画素を備え、第１保持部及び第２保持部は、光電変換部に生じた前記信号電荷をフレーム期間毎に交互に保持するとともに、光電変換部から信号電荷が転送されない期間において信号電荷を出力部へ出力する。【選択図】図２
