PROBLEM TO BE SOLVED: To appropriately track a specified object. SOLUTION: First, face detection is executed on an input image (S402), and the detected face region is registered as a reference image. A matching process by the reference image is applied to the next frame image, and a partial image which is high in the level of correlation is extracted (S405). When a condition for determining whether the track is to be continued is set (S406), whether the condition is satisfied is determined (S409); and when this is satisfied, the reference image is updated by the partial image by the matching process (S403). When the determination condition is not set, the reliability of the matching process is calculated and is compared with a threshold (S407, S408). When the reliability is not smaller than the threshold, the reference image is updated by the partial image by the matching process (S403). When the reliability is smaller than the threshold, a determination condition is set (S409); and whether the condition is satisfied is determined (S410). COPYRIGHT: (C)2010,JPO&INPIT
