Abstract
An image detection apparatus for detecting a target in an input image includes a database storing a target data unit, which includes information specifying the target to be detected, used color data, representative color data, and a cluster image; a representative color area extraction section for extracting an area having substantially the same color as the representative color from the input image as a representative color area; a candidate area extraction section for obtaining a candidate area possibly including the target from the representative color area, using relative positions of an area having the representative color and a frame of the cluster image; and a comparison section for comparing the cluster image and the candidate area and detecting the candidate area as an area including the target based on the comparison result.
