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 that is configured by a plurality kinds of micro lenses with different focusing distances that is disposed between the imaging element and the main lens and 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 kinds of micro lenses of the imaging element based on the distance so as to constitute one captured image.
