摘要：When the user sets an AF frame such that an object tracked as an AF target is inthe AF frame, an auto-tracking process starts to detect a face image from the imagecaptured by a television camera. Then, it is determined whether the face image is
detected from the peripheral range of the AF frame. If it is determined that the faceimage is detected from the peripheral range of the AF frame, the position of the AFframe is changed on the basis of the position of the face image. On the other hand, if it isdetermined that the face image is not detected from the peripheral range of the AFframe, a pattern matching process is performed. The position of the AF frame is changedto the position of the object, which is a tracking target, detected by the pattern matchingprocess.
