The similarity degree calculation unit is configured to calculate a degree of similarity between an image of the object and the registered image, using the parameter. The status acquisition unit is configured to acquire a registration status of the registered image. The generation unit is configured to generate a display screen including the registration status, and to output the generated display screen.
