Claim 0:
1. An imaging device, comprising:
an image sensor that exposes a subject image and repeatedly outputs image signals resulting from having subjected this subject image to photoelectric conversion at a fixed period;
a subject detection circuit, in which the image signals are input to a neural network circuit that has learned operation parameters for detecting a specified subject by deep learning, that detects the specified subject;
a subject association determination circuit for forming associations based on a positional relationship between a subject that has been detected by the subject detection circuit, and parts of the subject,
wherein the specified subject is a subject and parts; and
a positional relationship conditions circuit that determines a position relationship for the subject association determination circuit, wherein
the positional relationship conditions circuit performs judgment with a central position of a parts detection region that has been detected by the subject detection circuit being within a detection range of the subject that has been detected by the subject detection circuit, or a distance between centers of the subject and the parts detection region being in a specified range, as conditions, and
the positional relationship conditions circuit widens, or narrows, a range of a subject detection region in accordance with classification of the subject that has been detected by the subject detection circuit.
