The reliability evaluation unit is configured to evaluate a reliability of the motion vector between images and a motion vector in the feature amount area. The weight map creation unit is configured to create a weight map based on the motion vector between images, the reliability, and the motion vector in the feature amount area. The object tracking unit is configured to track the object based on the weight map.
