Abstract
Light transmitted through the imaging lensis divided into two light fluxes by the half mirrorfixed in the camera body, and two light fluxes are guided to the imaging elementand optical viewfinder, respectively. An image processing unit corrects aberration, which occurs due to the transmittance of light through the half mirror, of the image data generated after receiving light at the imaging element, by conversion processing based on a transfer function representing its optical transfer characteristics and restores the image data prior to the occurrence of aberration.
