Abstract
A tracking processing unit (137) performs a search in a frame using a color feature amount of an object and determines a target area estimated to include the image of the object based on the first evaluation value indicating a degree of matching between a search result and the object. An update detection circuit (139) performs a search in the frame using a shape feature amount of the object, calculates a second evaluation value, and determines an update area for updating a first feature amount based on the second evaluation value indicating a degree of matching between the search result and the object. An update determination circuit (140) determines whether or not to update the first feature amount. A tracking result drawing circuit (144) draws an outer frame of the target area when determined not to update, and draws that of the update area when determined to update.
