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.

An electronic device powered by a fuel cell and a power supply system using a fuel cell include a first generating cell supplied with fuel directly from a fuel tank and a second generating cell supplied with fuel through the first generating cell. The second generating cell has a capacity different from the capacity of the first generating cell.

Electronic device powered by fuel cell and power supply system using fuel cell

A fuel cell is disclosed, which can use space in an apparatus body effectively. The fuel cell comprises a plurality of cells laminated, and a cell box housing the plurality of cells. The plurality of cells include a cell whose size in a first direction orthogonal to a lamination direction is different from that of another cell. The cell box has a shape corresponding to the size of each cell. Furthermore, an electronic apparatus is disclosed, which comprises an apparatus body including a grip portion having a protruding shape; and a fuel cell that is housed in the grip portion and comprises a cell section in which a plurality of cells are laminated in a protrusion direction of the grip portion or a direction orthogonal to the protrusion direction.

Fuel cell, electronic apparatus and camera

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.

Imaging apparatus and control method utilizing biometric information

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 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.

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. The focus detection circuit detects the focused state of the objective using a light reception signal produced in a field other than the predetermined field on the light receiving sensor and a detection value produced by the first detection circuit. Herein, the focus detecting device is incorporated in a camera.
