A tracking device includes an imaging part for repeatedly acquiring image data on a subject image, a tracking processing part for setting a tracking position based on first image data to perform tracking processing on a subject in the tracking position based on second image data, and a relative distance information calculating part for calculating relative distance information using (1) a determined information about a distance to the tracking position and (2) a determined information about a distance to a surrounding area around the tracking position. When the tracking processing part determines that another subject in the surrounding area is located at the closer range than the subject in the tracking position, the tracking processing part prohibits tracking processing. |
