Abstract
An image capture apparatus includes an image sensor of a line-sequential scanning type, an optical database which stores optical characteristics of the optical system in advance, a calculation unit which calculates optical parameters including at least information of a focal length of the optical system for each area of the image sensor based on drive information of the image sensor and drive information of the optical system, a referring unit which refers to optical characteristics corresponding to the optical parameters calculated by the calculation unit of the optical characteristics stored in the optical database, a correction value generation unit which generates correction values used to correct the image signal based on the optical characteristics referred to by the referring unit, and a correction unit which corrects the image signal using the correction values generated by the correction value generation unit.
