<p>A detection object area is divided into a plurality of blocks, which are subjected to dimensional compression. Then, a characteristic vector formed by a representative value of each block is calculated. By using the characteristic vector, an identification device judges whether the detection object area contains a face image. That is, identification is performed after performing dimensional compression of the image characteristic amount to the extent that the characteristic of the face image is not deteriorated. Thus, the image characteristic amount used for identification is significantly reduced from the number of pixels contained in the detection object area to the number of blocks. Accordingly, the calculation amount is significantly reduced, enabling a high-speed face image detection.</p> |
