Patent ID: 8395677

Claim:
An aberration correction apparatus comprising: a correction data holding section that holds correction data on a correction level used to correct chromatic aberration of magnification, the correction data provided for each predetermined combination of aberration variation conditions that change a chromatic separation level due to the chromatic aberration of magnification and include at least an image height; a center position discrepancy data holding section that holds center position discrepancy data on the discrepancy between the center of an image area and the position of an aberration center of the chromatic aberration of magnification, the center position discrepancy data provided for each combination of predetermined discrepancy variation conditions that change the discrepancy; an aberration center calculating section that selects one of the center position discrepancy data that corresponds to a combination of the discrepancy variation conditions in an imaging apparatus and calculates the position of the aberration center based on the selected center position discrepancy data; an image height calculating section that calculates an aberration center corresponding image height of a processed pixel with respect to the position of the aberration center; a magnification chromatic aberration correction level calculating section that selects one of the correction data that corresponds to a combination of the aberration variation conditions in the imaging apparatus and calculates a magnification chromatic aberration correction level based on the selected correction data; and a pixel value correcting section that corrects the pixel value of the processed pixel based on the calculated magnification chromatic aberration correction level.
