Patent ID: 8743268

Claim:
An image capturing apparatus comprising: an image capturing unit which converts, into an image signal, an object image formed by an imaging optical system including a zoom lens; an image memory which stores an image signal obtained by said image capturing unit; a motion vector detection unit which detects a motion vector representing a shift amount between a stored image and an obtained image by said image capturing unit; an angle conversion unit which converts the motion vector detected by said motion vector detection unit into a pixel shift of the image capturing unit between the images on the basis of a first focal length; a shift angle calculation unit which calculates a shift angle from an optical axis of the imaging optical system based on the pixel shift calculated by said angle conversion unit, the shift angle being an integrated angular displacement from the optical axis; a correction pixel conversion unit which converts the shift angle calculated by said shift angle calculation unit into a correction pixel on an image plane of said image capturing unit on the basis of a second focal length, the second focal length being different from the first focal length; and a correction unit which corrects a shift to control a readout position in the stored image so as to cancel image blurring in the stored image in accordance with the correction pixel amount on the image plane, wherein a plurality of locus curves each representing a relationship between a quantity of the motion vector and the focal length with respect to each amount of the angular displacement are stored in the image memory, wherein the quantity of the motion vector varies in accordance with variation of the focal length with respect to each of the locus curves, and wherein the first focal length and the second focal length are sampled at different timings.
