Patent ID: 8692908

Claim:
An image-pickup apparatus comprising: an image-pickup element that photoelectrically converts an optical image formed by an image-pickup optical system having a zoom function; and a correction processing circuit that performs a correction processing using coordinate transformation for a distortion component in image data generated based on an output from the image-pickup element, the distortion component corresponding to a distortion of the image-pickup optical system, wherein the image-pickup optical system provides a first zoom range in which a distortion amount at a certain image height is larger than a predetermined value and a second zoom range in which a distortion amount at the certain image height is smaller than the predetermined value, wherein the correction processing circuit performs the correction processing so that the distortion component remaining in first corrected image data obtained by correcting the image data generated in the first zoom range is larger than the distortion component remaining in second corrected image data obtained by correcting the image data generated in the second zoom range, and wherein the distortion component remaining in each of the first and second corrected image data continuously changes according to a zoom position.
