Abstract
There is provided configuration for enabling extraction of the concerned area with simple operations. An arbitrary position within the desired concerned area is designated by the position designation means, and the pixel color of the designated position is stored in the memory. The tolerable color difference setting means sets the initial color difference from the pixel color of the designated position as 0. The pixel group (within tolerable color difference) extraction means extracts the pixels within the tolerable color difference from all the pixels. The adjacent pixel group (within tolerable color difference) selective display means selectively displays the pixel group including the pixel of the designated position, based on the result of extraction by the extraction means. At each execution by the selective display means, the tolerable color difference setting means increases the tolerable color difference. Thereafter the extraction means and the selective display means repeat the execution. The means and repeat the execution until the end of process is instructed.
