Abstract:
1. An imaging apparatus comprising an imaging apparatus body, and a lens unit removably mounted on the imaging apparatus body, wherein the lens unit includes an imaging optical system, and an identification storage unit that stores identification information specific to the lens unit, the imaging apparatus body includes an identification information acquisition unit that acquires the identification information from the identification information storage unit in the mounted lens unit, and an imaging unit capable of outputting a set of viewpoint images between which there is a disparity in a predetermined disparity direction by splitting a light flux from a subject, which has been focused via the imaging optical system in the mounted lens unit, into two or more light fluxes by pupil splitting along the disparity direction and focusing each of the light fluxes obtained by the pupil splitting onto a corresponding photoelectric conversion element group and photoelectrically convert the light flux, a correction table storage unit capable of storing a correction table storing a one-dimensional parameter for correcting one-dimensional shading occurring in the disparity direction in the set of viewpoint images output by the imaging unit along the disparity direction to correspond to the identification information acquired by the identification information acquisition unit, a determination unit that determines whether the correction table corresponding to the identification information of the mounted lens unit is stored in the correction table storage unit, and a shading correction unit that corrects, when the determination unit determines that the correction table corresponding to the identification information of the mounted lens unit is stored in the correction table storage unit, the shading in the set of viewpoint images according to the correction table, corresponding to the identification information of the mounted lens unit, stored in the correction table storage unit.
