摘要

A color recognition apparatus for classifying a color of a target region in an image by a clustering method so as to correspond to more pickup images influenced by an environmental change is provided.;In a stage of learning, a learning pickup image is classified into previously designated classified colors by the pixel to calculate a rate of each classified color, and clusters are formed based on the rate of the classified color of the learning pickup image in a color space composed of high rate classified colors in the classified colors, and in a stage of recognizing, a recognition target image is classified into preciously designated classified colors by the pixel to calculate a rate of the classified color, a distance between a barycenter of the formed cluster in the color space and coordinates corresponding to the rate of the classified color of the recognition target image to specify the shortest distant cluster formed in the color space, and a color is selected from the designated colors corresponding to the specified cluster to be recognized.
