An image-capturing apparatus includes: an optical system having a variable power function; microlenses; an image sensor having pixel groups each including pixels, receiving light having passed through the optical system and the microlenses at the pixel groups, and outputting a signal based on the received light; and an image processing unit generating an image focused on one point of an object among objects at different positions in an optical axis direction, based on the sensor signal output. If a range length in the optical axis direction specified by a focal length in which the optical system focuses on one point of a target object is longer than a length based on the object, the unit generates a first image focused on one point in the range, and if the range length is smaller, the unit generates a second image focused on one point outside and one within the range.
