An object tracking apparatus includes a motion vector calculation unit, a feature amount area determination unit, a reliability evaluation unit, a weight map creation unit, and an object tracking unit. The motion vector calculation unit is configured to calculate a motion vector between images. The feature amount area determination unit is configured to determine an area of an object detected from an image as a feature amount area. 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.
