Abstract
An image processing apparatus for processing signals read out from an image sensor that includes a plurality of photoelectric conversion portions for each of a plurality of micro-lenses, and can read out signals for each row selectively by either an addition readout operation, or a divisional readout operation. The image processing apparatus includes a first processing unit to perform offset correction on signals of a first row read out by the addition readout operation using signals in two or more rows that were read out by the addition readout operation before the first row, and a second processing unit to perform offset correction on signals of a second row read out by the divisional readout operation using the signals of the second row and a predetermined value.
