<P>PROBLEM TO BE SOLVED: To prevent a matter erroneously detected as a face, from being tracked long. <P>SOLUTION: A frame image acquisition part 51 sequentially acquires image data. A face detection part 52 detects a face which is estimated to be a subject, from each piece of image data sequentially acquired by the frame image acquisition part 51. A face reliability calculation part 41 calculates reliability expressing subject likelihood, with respect to a detected face detected by the face detection part 52. A tracking period setting part 42 sets a tracking period for tracking the detected face, on the basis of the reliability calculated by the face reliability calculation part 41. A tracking part 15 tracks the detected face detected by the face detection part 52 from image data to be sequentially acquired the next time and thereafter by the frame image acquisition part 51. A tracking control part 44 performs control to track the detected face, on the basis of the tracking period set by the tracking period setting part 42. <P>COPYRIGHT: (C)2012,JPO&INPIT |
