<P>PROBLEM TO BE SOLVED: To automatically perform optimum edge enhancement processing by determining image sharpness with simpler method. <P>SOLUTION: In an edge-enhancement processing apparatus, a computer main body, as the nucleus of edge enhancement processing, calculates an edge amount as vector change level while generating a vector based on the difference values of data between adjacent pixels, at step S110, then selects and integrates edge amounts of only pixels having large edge amounts at steps S120 and S130, and obtains the mean value, to obtain the sharpness level of the image while adding attention to the pixels having large image change levels. An edge enhancement level Enhance is determined based on the image sharpness level. Thus, edge enhancement processing is performed automatically at an optimum enhancement level. <P>COPYRIGHT: (C)2008,JPO&INPIT |
