1. A light receiving device comprising:
a plurality of first filters that each transmit an edge component in a predetermined direction in an incident image;
a plurality of second filters that each transmit light of a predetermined wavelength band in incident light; and
a plurality of photoelectric conversion elements that each photoelectrically convert light transmitted through one of the plurality of first filters and one of the plurality of second filters,
wherein each of the plurality of first filters includes a third filter that transmits an edge component in a first direction and a fourth filter that transmits an edge component in a second direction different from the first direction.
