Patent ID: 8446477

Claim:
An imaging apparatus comprising: a shift lens that is driven to be shifted; a uniform aberration correction data storing unit that stores uniform aberration correction data for correcting uniform aberration that is a component of chromatic aberration of magnification in which a direction of color deviation and an amount of color deviation uniformly occur over the entire image; a shift amount calculating unit that calculates an amount of aberration correction shift of the shift lens for correcting uniform aberration using the uniform aberration correction data; a shift lens driving unit that drives the shift lens to be shifted according to an amount of driving shift based on the amount of aberration correction shift; a concentric aberration correction amount calculating unit that calculates an amount of concentric aberration correction for correcting concentric aberration that is a component of chromatic aberration of magnification causing a concentric color deviation from the center of the image, with respect to a process target pixel of an input image signal; and a pixel value correcting unit that corrects a pixel value of the process target pixel on the basis of the calculated amount of concentric aberration correction.
