ABSTRACT:
An image processing apparatus for performing a tracking of a moving object by setting a tracking area corresponding to a moving object appearing in a video image, by setting a plurality of feature points in the tracking area, and by tracking the plurality of feature points, comprises a tracking processing unit for tracking each of the plurality of feature points from the preceding frame to the present frame, and a motion calculation processing unit for specifying a position of the tracking area in the present frame by estimating the motion of the tracking area based the tracking result of each of the feature points, wherein the tracking processing unit calculates reliability indicating the height of the possibility that a feature point exists in the moving object to each of the feature points, and the motion calculation processing unit calculates the motion of the tracking area by using the reliability.
