Abstract
An apparatus includes a memory configured to store instructions and a processor in communication with the memory and configured to execute the instructions to generate a composite map from a plurality of images having different in in-focus position in an optical axis direction, correct the composite map, and combine the plurality of images using the composite map corrected by the correction unit to generate a composite image, wherein a depth of field of the composite image is deeper than a depth of field of each of the plurality of images, and further detect a first region surrounded by values each representing a composition ratio in the composite map and each different from an outer periphery by a first threshold or more, determine a correction value from a second region in the outer periphery of the first region, and correct the first region using the correction value.
