<P>PROBLEM TO BE SOLVED: To sharpen an image in which a focused region and an unfocused region are mixed. <P>SOLUTION: The method estimates a circle of confusion C that indicates the range of peripheral pixels 2 which influences the color information of a target pixel 1, with each of all pixels constituting a subject image being the target pixel 1, and restores the color information of the target pixel 1 to a state where there is no influence of the peripheral pixels 2, using an inversion filter of a blurring function based on the inferred circle of confusion C. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
