Patent ID: 8537225

Claim:
An image pickup apparatus comprising: an image pickup optical system; an image pickup element for photoelectrically converting an image formed by the image pickup optical system; an image processing unit for performing an image process on a taken image; a shake detection unit for detecting a shake of the image pickup apparatus; an image stabilizing unit for decentering an image stabilizing lens unit formed as a part of the image pickup optical system based on a detection result from the shake detection unit, wherein the image processing unit performs the image process to reduce a decentering aberration generated by decentering of the image stabilizing unit using an image restore filter based on an averaged point spread function obtained by calculating a mean value of point spread functions corresponding to respective positions of the image stabilizing lens unit during the exposure time at a time of image taking, and wherein the image restore filter is obtained on the basis of a point spread function having a rotational asymmetry with respect to an optical axis.
