An object tracking apparatus includes a motion vector detection circuit in which a correlation value for each of detection blocks are evaluated by a first correlator on the basis of a portion motion vector of each of the detection blocks and a reference vector. If the correlation value is smaller than a threshold value, the detection block corresponding to the correlation value is regarded as a detection block constituting a tracking area. A gravity of the tracking area is detected by a gravity detection circuit, and a motion vector is generated by a motion vector generator on the basis of the gravity. A universal head is driven in accordance with the motion vector, whereby a specific object can be tracked automatically. <IMAGE> |
