PROBLEM TO BE SOLVED: To provide an imaging apparatus capable of generating both an imaging signal and a focus detection signal from an imaging element, with a small amount of correction data.SOLUTION: An imaging apparatus includes an imaging element which includes a plurality of pixels corresponding to a plurality of microlenses, respectively, and includes a first photoelectric conversion part and a second photoelectric conversion part included in one of a plurality of pixels so as to share one of a plurality of microlenses, and a signal processing section for correcting a first signal, generated using addition signals outputted from the first and second photoelectric conversion parts included in one pixel, and a plurality of signals from a plurality of first photoelectric conversion parts corresponding to the plurality of microlenses. The signal processing section corrects the addition signal for each pixel, and corrects the first signal for each of the plurality of first photoelectric conversion parts. 【課題】少ない補正データ量で、撮像素子から撮像信号および焦点検出信号の両方を高精度に生成可能な撮像装置を提供する。【解決手段】撮像装置は、複数のマイクロレンズのそれぞれに対応する複数の画素を備え、複数のマイクロレンズのうちの一つのマイクロレンズを共有するように、複数の画素のうちの一画素に含まれる第１光電変換部および第２光電変換部を備えた撮像素子と、一画素に含まれる第１光電変換部および第２光電変換部からの出力の加算信号、および、複数のマイクロレンズに対応する複数の第１光電変換部の複数の信号を用いて生成された第１の信号を補正する信号処理部とを有し、信号処理部は、一画素ごとに加算信号を補正し、複数の第１光電変換部ごとに第１の信号を補正する。【選択図】図９
