Claim:
1. An image processing method for processing image data generated by an image sensor having a plurality of pixels, each pixel having a microlens and a plurality of photoelectric converters including a first photoelectric converter and a second photoelectric converter, the method comprising: receiving images of a plurality of frames from the image sensor; and generating a recomposed image by adding a first signal obtained by the first photoelectric converter of the plurality of pixels of the image sensor and a second signal obtained by the second photoelectric converter of the plurality of pixels in a state that a position of the second signal is shifted with respect to a position of the first signal, a position of a focal plane of the recomposed image being changed by changing a shift amount of the position of the second signal with respect to the position of the first signal, the focal plane being a plane where light incident on the first photoelectric converter and light incident on the second photoelectric converter are imaged; wherein, in a case where the recomposed image is generated from an image of a first frame among images of the plurality of frames received from the image sensor, the position of the focal plane of the recomposed image generated from the image of the first frame is set in accordance with a position of a focal plane corresponding to an image of a second frame different from the first frame among the plurality of frames.
