Abstract:
An image area extracting apparatus that extracts a desired area from an image, comprising:a boundary area dividing unit that divides rough image corresponding to said image, in which boundary area between said desired area and areas other than said desired area is roughly assigned, into a plurality of small areas;object area extracting means for detecting the desired area and areas other than said desired area from said each small area by executing area extracting means to each of said small areas; anda boundary mask forming unit for forming a boundary area mask image of said roughly assigned boundary area between said desired area and areas other than said desired area depending upon said detection result and extracts said desired area based on said boundary mask image;a non-boundary mask area mask forming unit that forms a non-boundary area mask image of said areas other than said roughly assigned boundary area;a synthesizer that synthesizes the boundary area mask image and the non-boundary mask image to form a synthesized mask image for assigning the desired area.
