发明名称 IMAGING APPARATUS, METHOD OF CONTROLLING IMAGING APPARATUS
摘要 An imaging apparatus receive light fluxes passing through and incident on different pupil regions of an imaging optical system and generates at least image data of one pair of subject images. Imaging surface correction information regarding a manufacturing error or optical characteristics of design of an imaging lens is transmitted from a lens control unit of the imaging lens to a system control unit of a camera body, and then the system control unit receives the imaging surface correction information. The system control unit performs a process of generating a defocus map based on a parallax between at least one pair of images and performs imaging surface correction through correction of the calculated defocus amount. In the imaging surface correction process, influences of the optical characteristics of the imaging lens and an inclination of an imaging surface of an image sensor are corrected, and thus a more accurate distance map is generated.
