1. A judgement method for a judgement device, comprising:
by a computer of the judgement device,
selecting two or more living body judgement processes among a plurality of living body judgement processes for judging whether a subject contained in an image is of living body;
determining an order of executing the two or more selected living body judgement processes;
executing the two or more selected living body judgement processes in the determined order;
executing, in each of the two or more selected living body judgement processes: (1) a processing of showing a subject an action required for the living body judgement process; (2) a processing of acquiring a facial image containing a face of the subject when acting in accordance with the shown action; and (3) a processing of judging whether the subject is of living body based on a feature of a section of the face contained in the facial image;
determining whether judgement results obtained from the two or more selected living body judgement processes satisfy a predetermined condition; and
judging that the subject is of living body when the judgement results satisfy the predetermined condition, and judging that the subject is not of living body when the judgement results fail to satisfy the predetermined condition,
wherein, prior to the selection of two or more living body judgment processes from among the plurality of living body judgement processes, a state of the subject is detected, and
the selection of two or more living body judgment processes includes eliminating any living body judgement process that includes an action unsuitable for judging whether the subject contained in the image is of living body based on the detected state of the subject.
