Abstract: The camera includes a sensor for sensing the photographer's iris image and registering the image in advance. The iris image is recorded in the image of a subject by a digital MCU at a timing different from that at which the image of the subject is captured. The recording timing is that at which the camera power supply is turned off, that at which a recording medium is ejected from the camera or that at which the iris image to be recorded is changed to changed to the registered iris image of another photographer. The recording of the iris image is achieved by embedding it as a watermark or by appending it to metadata.

Abstract: A digital still camera records a photographer's biological information on a photographic image reliably and protects the copyright of photographic images without affecting processing, and in a manner transparent to operation, at the time of photographing a subject. Biological information (iris information) that is registered beforehand by the photographer is recorded as personal data on an ID card. If an image is taken in a state in which the ID card bearing the recorded personal data has been inserted into the apparatus, iris information that has been sensed by an iris sensor is checked when a power supply is turned on. If the two compared items of iris information match, the personal data is added onto the image of the photographed subject.

Abstract: Disclosed is a focus detecting device consisting mainly of a light receiving sensor, a reflecting mirror, a first detection circuit, and a focus detection circuit. The light receiving sensor has a plurality of photoelectric converters. The reflecting mirror is movable between a first position at which the reflecting mirror reflects light that comes from an objective, and routes the light to the light receiving sensor, and a second position at which the reflecting mirror recedes from the path of the light coming from the objective. The reflecting mirror has a member that helps form light distributions in a predetermined field on the light receiving sensor. Moreover, the reflecting mirror makes a return from the first position to the second position or vice versa. The first detection circuit detects a change in the light distributions formed in the predetermined field on the light receiving sensor which is observed between before and after the reflecting mirror makes a return.
