Claim Text:
1. An image sensing apparatus comprising: an image sensing unit configured to output data in which respective pixels of image signals of each frame correspond to light beams having different pupil regions through which the light beams have passed in an imaging optical system; at least one processor or circuit configured to perform the operations of the following units: a display unit configured to perform a display of an image on a display; a detection unit configured to detect a specific subject in the image; a decision unit configured to decide a focal position at which the specific subject detected by the detection unit is focused on; a driving unit configured to decide a driving position of the focus lens based on the focal position decided by the decision unit, and drive the focus lens to the driving position; and a recording unit configured to record, on a recording medium moving data including a plurality of frames of the data output from the image sensing unit after driving the focus lens by the driving unit; wherein the decision unit generates, from the image signals of a frame of the data, a pair of images respectively corresponding to light beams having passed through different pupil regions of the imaging optical system and calculates, for the decision of the focal position, an image position shift between the pair of images.
