1. An image capturing apparatus comprising: an imaging element; a main lens that condenses light from a subject toward the imaging element; a micro lens array which includes a plurality of kinds of micro lenses with different focusing distances, which is disposed between the imaging element and the main lens, and which causes light transmitted through the main lens to form an image on the imaging element; and an image processing unit that, in response to receiving a designation of a distance to a side of a subject that is photographed, performs weighting for each image that is imaged by the plurality of kinds of micro lenses based on the distance so as to form a captured image.
