It discloses a display apparatus with a camera capable of taking an almost full-face image of a person seeing a display. The display apparatus with the camera includes a display element in which display pixels are arranged, and an image-taking module which forms a plurality of object images through a plurality of aperture areas formed among the display pixels of the display element and photoelectrically converts the plurality of object images. Furthermore, the display apparatus includes an image combining section which combines image information on the plurality of object images obtained by using the image-taking module.

Display apparatus with camera and communication apparatus

A photographing apparatus which realizes a taking lens barrel whose shape is not largely changed during panning or tilting shot, thereby being compact in size and easy to handle. In the photographing apparatus, an image pickup device () outputs an electric signal from object light. A bending optical system () has a front lens () and lens groups (, and) and a mirror () disposed between the front lens and the laminated lens, to guide the object light to the image pickup device. A panning actuator () and a tilt actuator () cause the mirror and the front lens or the lens groups to be pivotally moved in unison about respective different axes to thereby change a shooting direction.

Photographing apparatus and control method therefor

There is provided an image pickup apparatus which has a plurality of photoelectric conversion regions and a plurality of reflectors disposed so as to lie around the photoelectric conversion regions when viewed from the light incident direction, and which is constructed such that each reflector reflects at least one part of the light from one of the photoelectric conversion regions towards one of the other photoelectric conversion regions adjacent to the one photoelectric conversion region.

Image pickup apparatus

An optical device capable of controlling its optical transmittance. The optical device has a first liquid conductive or having a polarity and a second liquid. The first and second liquids are substantially equal in refractive index but differ in transmittance. The first and second liquids do not mix with each other. The first and second liquids are sealingly contained in a container in such state that the boundary therebetween has a predetermined shape. When a voltage is applied between these liquids through electrodes formed in such a place or condition as to avoid interference with passage of a bundle of rays incident upon the optical element, the output of the applied voltage is selected under control to change the shape of the boundary, thereby changing the quantity of transmitted light in the bundle of rays traveling through the optical device.

Optical element

An optical apparatus includes a barrier member disposed in front of a lens and arranged to be openable and closable, an urging member arranged to exert an urging force on the barrier member, and an abutting member arranged to be capable of abutting on the urging member, wherein, when the abutting member abuts on the urging member, the urging member exerts on the barrier member an urging force acting in a direction of closing the barrier member, and, when the abutting member does not abut on the urging member, the urging member exerts on the barrier member an urging force acting in a direction of opening the barrier member.

Optical apparatus

An apparatus adapted for use with a solar cell, such as a camera, includes a body and a cover member to which the solar cell is attached, where the cover member is movable between an open position and a closed position with respect to the body of the apparatus. The apparatus further includes an air layer providing member which provides an air layer between the cover member and the body of the apparatus when the cover member is in the closed position, thereby reducing transmittance of heat from the solar cell to the body of the apparatus.

Equipment using solar battery

A camera includes a plurality of camera operation mechanisms, a sun gear which rotates by means of a motor, a planetary gear which revolves around the sun gear, and a plurality of output gears each capable of meshing with the planetary gear by means of revolution of the planetary gear. The plurality of output gears transmit power to the plurality of camera operation mechanisms, respectively. A holding member is switchable from a first state, in which the planetary gear is allowed to revolve freely, to a second state, in which the planetary gear is held at a revolution position where the planetary gear is in mesh with one of the plurality of output gears. A controller causes the planetary gear to revolve so as to mesh with a selected one of the plurality of output gears, and switches the holding member from the first state to the second state, after completion of a power transmitting operation.

Camera featuring a single drive source and a plurality of selectable drive transmission mechanisms

A camera includes a plurality of camera operation mechanisms, a sun gear which rotates by means of a motor, a planetary gear which revolves around the sun gear, and a plurality of output gears each capable of meshing with the planetary gear by means of revolution of the planetary gear. The plurality of output gears transmit power to the plurality of camera operation mechanisms, respectively. An unlocking device removes backlash by causing the planetary gear to rotate temporarily in an opposite direction when the planetary gear is to be switched from one of the plurality of output gears in mesh therewith, to another one of the plurality of output gears. A locking device prevents the planetary gear and such one output gear from coming out of mesh with each other until the backlash is removed when the unlocking device causes the planetary gear to rotate in the opposite direction.

Power transmission apparatus including plural selectable drive transmission mechanisms usable with single drive source, and camera using same

An apparatus, such as a camera, comprises a plurality of operation mechanisms, a first rotation member, such as a sun gear, rotatable by operation of a motor, a second rotation member, such as a planetary gear which revolves around the sun gear, and a plurality of force transmitting members, such as output gears, each capable of meshing with the planetary gear by revolution of the planetary gear around the sun gear, where the plurality of output gears transmit power to the plurality of operation mechanisms, respectively, and a limiting structure, e.g., a stopper that limits revolution of the planetary gear around the sun gear. In one aspect, the limiting structure limits the revolution of the planetary gear at a revolution position where the planetary gear does not mesh with any of the plurality of output gears, and a position of the planetary gear during revolution thereof is determined on the basis of the position where revolution of the planetary gear is limited by the limiting structure, e.g., by determining an amount of revolution of the planetary gear relative to the position where the revolution of the planetary gear is limited by the limiting structure.
