Abstract:
A photoelectric conversion unit includes a plurality of photoelectric conversion devices for receiving light from an object and storing charge corresponding to the quantity of the received light. A monitor unit outputs a monitor signal corresponding to the received light quantity from the start of the charge storage by the photoelectric conversion unit. When a predetermined time elapses from the start of the charge storage by the photoelectric conversion unit, a monitor read unit reads out the output monitor signal from the monitor unit. A time determining unit determines a charge storage end time on the basis of the monitor signal read out by the monitor read unit. When the charge storage end time determined by the time determining unit elapses, a signal read unit reads out charge signals stored in the photoelectric conversion devices of the photoelectric conversion unit.
Abstract:
A focus detecting device comprising a condenser lens disposed in the vicinity of a predetermined image surface of a photographic lens system, separator lenses disposed on the side of emergence of the condenser lens and functioning to partially separate a pair of light bundles having passed through different regions respectively of the photographic lens system. The focus detecting device can use, in place of the separator lenses, a reimaging lens having reflecting surfaces which can function also as aperture stops and are formed on a plane including a center of curvature of the surface thereof. This focus detecting device can be made compact and is capable of detecting a focus point with high accuracy.

Abstract:
A camera for image pickup on a film and also for electronic image-sensing comprises an electronic image-sensing apparatus having an image sensing device for transforming a subject image into an electric signal, a monitor for displaying the subject image on the basis of an picture signal outputted from this electronic image-sensing apparatus, an apparatus for taking a picture on a film for exposing a silver halide film to the subject image, an image pickup lens for forming the subject image on the image sensing device and the silver halide film, a reflection type of movable mirror for guiding to an optical finder a subject light beam passing through the image pickup lens, and an optical guide, located between the image pickup lens and movable mirror, for guiding to the image sensing device a part of image pickup light beam.
Abstract:
A light beam passing a photographing lens is divided into two portions by a mirror in a camera body. One of the two divided light beams is directed to an eyepiece via a screen and pentagonal prism. The other divided light beam is reflected from a mirror and directed to a focus detection optical system constructed by a field view diaphragm, condenser lens, diaphragm mask and re-imaging lens, and an image in position corresponding to the range-finding field view is divided into two images by the optical system. An image sensor is arranged near the re-imaging surface which receives the two images formed by the focus detection optical system to photoelectrically convert a received signal and transfer data to a CPU. The CPU effects the focus detection operation containing the operation of interpolating the value of correlation between the two images by use of the self-correlation value of one of the two images based on detection data and drives the photographing lens to a focused position.
Abstract:
A plurality of lens groups are moveable in the direction of an optical axis. A plurality of motors are provided for the lens groups, respectively. A driving circuit drives the motors. A switching section sequentially selects the motors and connects the selected motors to the driving circuit. A lens position-detecting section detects the positions of the lens groups. A driving control section sequentially drives the lens groups in accordance with intermediate target position data, respectively, via the switching section and the driving section, and determines whether the lens groups have reached their respective intermediate target positions, on the basis of the detection performed by the lens position-detecting section. When the driving control section determines that the lens groups have reached their respective intermediate target positions, it demands next intermediate target positions, which are slightly away from the initially-determined intermediate target positions. On the basis of the next intermediate target positions, the lens groups are driven again. With this operation repeated, the driving control section controls the driving of the lens groups until these lens groups reach their respective final target positions.
Abstract:
Image data obtained by photographing an object using a camera is stored in a storage medium that can be attached to and detached from the camera. The camera includes a device program storage unit and an information writing unit. A device program that can be executed by an information processing device, which is different to the camera, is stored in the device program storage unit. The information writing unit is constituted to be capable of writing the device program to the storage medium attached to the camera. While writing the device program to the storage medium, the information writing unit writes the device program in a format enabling the information processing device to read and execute the device program automatically when the storage medium is attached to the information processing device.
Abstract:
Organic electroluminescence (EL) devices displaying the information of a camera are formed directly on a surface of a screen mat arranged near an image formation surface of a finder optical system. A CPU for the camera drives the organic EL device, under a forward or a reverse bias, as required, to enable light of a green or a red color to be emitted.
