PROBLEM TO BE SOLVED: To provide an imaging apparatus and an imaging system that are able to obtain a moving image of a wide dynamic range while carrying out high-performance automatic focus.SOLUTION: An imaging apparatus includes: first and second photoelectric conversion parts on which pupil-split light is made incident; and a holding part that holds electric charges transferred from the first and second photoelectric conversion parts. The imaging apparatus has a pixel that outputs a signal based on the electric charges of a holding part. The pixel is configured to output a first signal based on charges generated in the first photoelectric conversion part during a first exposure time; a second signal based on electric charges generated in the first and second photoelectric conversion parts during the first exposure time; a third signal based on electric charges generated in the first photoelectric conversion part during a second exposure time; and a fourth signal based on electric charges generated in the first and second photoelectric conversion parts during a second exposure time. During one frame period, the first and second signals are output before the third and fourth signals. In another frame period, the first and second signals are output after the third and fourth signals.SELECTED DRAWING: Figure 5 【課題】高性能なオートフォーカスを行いながら、広いダイナミックレンジの動画像を取得しうる撮像装置及び撮像システムを提供する。【解決手段】瞳分割された光が入射する第１及び第２光電変換部と、第１及び第２光電変換部から転送される電荷を保持する保持部とを含み、保持部の電荷に基づく信号を出力する画素を有し、画素は、第１露光時間の間に第１光電変換部で生じた電荷に基づく第１の信号と、第１露光時間の間に第１及び第２光電変換部で生じた電荷に基づく第２の信号と、第２露光時間の間に第１光電変換部で生じた電荷に基づく第３の信号と、第２露光時間の間に第１及び第２光電変換部で生じた電荷に基づく第４の信号とを出力するように構成されており、一のフレーム期間では第１及び第２の信号は第３及び前記第４の信号よりも前に出力され、他のフレーム期間では第１及び第２の信号は第３及び前記第４の信号よりも後に出力される。【選択図】図５
