Abstract
The present invention provides for designation of a prescribed area within an image as an initial extracting area, extraction of an area which fulfills the conditions determined according to the characteristics of the specific image from an image signal of an image, generation of comparative area signal presenting an area slightly larger than the extracted area which is necessary for fulfilling the conditions from the area extracting signal of the designated initial extracting area, comparison of the comparative area signal that has been generated with the candidate area signal through which the initial extracting signal of the initial extracting area is converted into an area extracting signal, and extraction of an image signal within the area determined by the new area extracting signal. As a result, the image which fulfills the conditions other than the specific image is eliminated as the extracted area that has been set as an initial extracting area changes to coincide with the specific image and only the object image which fulfills the conditions is extracted. Furthermore, since the area extracting signal is stored in a memory and used for generation of the next area extractin…
