It is possible to obtain the distance to an object with high precision, and it is also possible to obtain a high-quality image. Provided is an image-capturing apparatus including an image-capturing lens that focuses light from a subject; an aperture member disposed adjacent to the image-capturing lens; an image-capturing device that captures an image of the light focused by the image-capturing lens and passing through the aperture member; and a microlens array disposed between the image-capturing device and the image-capturing lens, with gaps therebetween in an optical-axis direction, wherein the aperture member includes at least one normal aperture portion having a substantially circular opening and at least two coded aperture portions having openings in a prescribed pattern.
