Patent ID: 8531582

Claim:
An imaging apparatus comprising: an optical element that is obliquely disposed relative to the optical axis of an imaging lens in order to reflect and transmit a part of the light transmitted through the imaging lens; an optical viewfinder that is capable of observing a subject with light reflected from the optical element; an imaging element that receives light transmitted through the optical element to output image data; and an image processing unit configured to correct aberration, which occurs due to the transmittance of light through the optical element, of the image data obtained by the imaging element, by conversion processing based on a transfer function according to the optical element and restore image prior to the occurrence of aberration, wherein the image processing unit corrects aberration having a symmetry in a first axial direction based on a transfer function according to the optical element, and aberration having an asymmetry in a axial second direction that is perpendicular to the first axial direction and an optical axis of the optical element and is a travelling direction of the light reflected by the optical element based on the transfer function according to the optical element, wherein a value inverted from left to right is employed for a transfer function value at a position symmetrical to the first axial direction.
