Abstract
An imaging apparatus includes an imaging device, a light guide mechanism, and a signal processing unit. The imaging device converts light incident on a photoelectric conversion portion of the imaging device into electric signals. The light guide mechanism, arranged adjacent to the photoelectric conversion portion of the imaging device, includes a plurality of apertures that guide light from a subject to the photoelectric conversion portion of the imaging device. The signal processing unit performs desired signal processing on the electric signals output from the imaging device on the basis of subject information units derived from the light guided onto the photoelectric conversion portion of the imaging device through the apertures.
