An image capturing device (1) includes: a microlens array (33) including a plurality of micro condenser lenses (34) arranged at a focal position of an imaging optical system for forming a plurality of erect equal-magnification images; and an imaging unit (31) including light-sensitive pixels (32x) provided at positions corresponding to the micro condenser lenses 34. Micro condenser lenses (34) have refractive powers to condense, among light rays incident from the imaging optical system, light rays incident at an incident angle within a predetermined limited angle range, onto positions different from positions on which light rays incident at an incident angle outside the limited angle range are incident. Effective light-sensitive regions of the light-sensitive pixels (32x) receive only light rays incident at an incident angle within the limited angle range among light rays entered micro condenser lenses (32).
