<P>PROBLEM TO BE SOLVED: To provide a tracking device and method capable of highly accurately detecting occurrence of erroneous tracking when performing tracking based on a feature of a tracking target. <P>SOLUTION: A tracking device for tracking the position of a tracking target in a moving image executes processing for tracking a subject using feature information of the tracking target for a current processing target frame image to thereby detect a tracking target position at this time, extracts an image between the tracking target position at this time and a tracking target position at the last time from the processing target frame image, and determines whether a tracking target position detected based on similarity between the extracted image and the feature information is outside the tracking target. The tracking device, when it is determined that the detected tracking target position is not outside the tracking target, holds the tracking target position at this time as the tracking target position at the last time to be used in the determination. <P>COPYRIGHT: (C)2012,JPO&INPIT |
