Abstract
An image tracking apparatus includes: an imaging unit that repeatedly captures an image formed through an imaging optical system to generate a photographing image; a calculation unit that sets a first search region and a second search region other than the first search region in the photographing image, calculates a first calculation result indicating correlation between image information on the first search region and reference information based on a target image, and calculates a second calculation result indicating correlation between image information on the second search region and the reference information; and a detection unit that detects a position of the target image in the photographing image based on either one of the first calculation result and the second calculation result.
