OBJECT TRACKING DEVICE CAPABLE OF TRACKING OBJECT ACCURATELY, OBJECT TRACKING METHOD, AND STORAGE MEDIUM

摘要

An object tracking device capable of accurately tracking an object as a tracking target. The device receives an image signal having a plurality of frame images and tracks a specific object in the image signal. The device sets a predetermined number of small areas in a reference area indicative of an area where an image of the object is formed in the preceding frame image. The object tracking device detects a motion vector of the object in each of the small areas, and determines a change of the object according to the motion vector to thereby obtain shape change information. The device corrects the location and size of the reference area according to the shape change information to thereby correct the reference area to a corrected reference area, and tracks the object using the corrected reference area.
