19. A non-transitory computer-readable medium storing a computer program for implementing a tracking method, the tracking method comprising:
exposing a subject image and repeatedly outputting image signals that have been subjected to photoelectric conversion at a fixed period,
detecting the specified subject using a neural network circuit that has learned operation parameters for detecting the subject, from the image signals;
forming associations based on a positional relationship between body portions and part portions, in the specified subject that has been detected, wherein
the specified subject is a subject and parts;
determining a position relationship;
performing judgment with a central position of a parts detection region being within a detection range of the subject, or a distance between centers of the subject and the parts detection region being in a specified range, as conditions; and
widening, or narrowing, a range of a subject detection region in accordance with classification of the subject.
