Claim One:
1. A face image extraction device for defining a face in a target image by position and size for extraction, comprising: an edge extraction part for extracting an edge part (pixels outlining a person or face) from said target image, and generating an image having only the edge part (hereinafter, edge image); a template storage part for storing a template composed of a plurality of predetermined concentric shapes equal in shape but varied in size; a voting result storage part for storing, in a interrelating manner, voting values and coordinates of pixels on said edge image for every size of the concentric shapes of said template; a voting part for increasing or decreasing said voting values of every pixel, specified by the coordinates, outlining each of said concentric shapes every time a center point of said template moves on the pixels in said edge part; and an analysis part for defining the face in said target image by position and size based on said voting values stored in said voting result storage part.
