An image capture apparatus functions as an object tracking apparatus for tracking an object included in provided images, registers a partial image indicating an object as a template, and performs template matching for estimating a region by using the template and histogram matching for registering a histogram of a partial image indicating the object and estimating a region by using the histogram. In a case where a distance between the estimation region based on the histogram matching and the estimation region based on the template matching is within a predetermined range, the estimation region based on the template matching is employed as an object region, and in a case where the distance between the estimation region based on the histogram matching and the estimation region based on the template matching is not within the predetermined range, the estimation region based on the histogram matching is employed as the object region.
