Patent ID: 8120666

Claim:
An image pickup apparatus comprising: a chromatic aberration of magnification correction device configured to correct chromatic aberration of magnification of an image by converting coordinates of multiple color components of pixel data of the image by using multiple first coordinate conversion memories respectively storing the multiple color components and moving at least two of the multiple color components within respective first coordinate conversion memories associated with said pixel data to a common pixel location different from an original pixel location of the pixel data such that the first coordinate conversion memories contain chromatic aberration of magnification corrected values; and a distortion correction device configured to correct distortion of the image corrected with regard to the chromatic aberration of magnification by converting coordinates of the pixel data of multiple color components of the image simultaneously using a second coordinate conversion memory shared by the multiple color components and moving the chromatic aberration corrected values at the common pixel location to the original pixel location, wherein the first coordinate conversion memories are memories having a first capacity with a first latency or a first capacity with multiple ports and the second coordinate conversion memory is a memory having a second capacity higher than the first capacity with a second latency higher than the first latency or a second capacity with a single port in comparison with the memories for the first coordinate conversion memories.
