Abstract
Official abstract text for this publication.
Edge enhancement processing is implemented on an image data, and distortion correction processing is implemented on the image data subjected to the edge enhancement processing to correct a distortion by executing local enlargement processing or reduction processing corresponding to an optical distortion characteristic of a lens employed during an image pickup operation. At this time, the edge enhancement processing performed on the image data to be subjected to the distortion correction processing is modified in accordance with the local enlargement processing or reduction processing.
First claim
Opening claim text (preview).
What is claimed is: 1. An image processing apparatus comprising: an edge enhancement unit that implements edge enhancement processing on an input image data; a distortion correction unit that implements distortion correction processing on the image data subjected to the edge enhancement processing to correct a distortion by executing local enlargement processing or reduction processing corresponding to an optical distortion characteristic of a lens employed during an image picku…
