摘要： A circuit is disclosed for controlling the drive motor of a motor driven camera in a single frame shot mode, A continuous shooting mode and a bulb mode. The circuit includes provision for controlling the camera from a plurality of positions. A release circuit controls the motor until the shutter is released. Then a film winding circuit controls. The time constant of the film winding circuit may be varied to control the duration between successive shots in a continuous shot mode. For a single shot mode, the film winding circuit is effectively blocked from operating the motor until the release button is no longer depressed.

摘要： An exposure display device for a single lens reflex camera including light display elements for displaying either shutter speed or diaphragm value is disclosed. Nominal values representing either shutter speed or diaphragm value are marked on a glass plate disposed in the vicinity of the focusing plate of the camera's viewfinder. A first display section, comprising a first set of light display elements aligned with (and, if desired, located inbetween) the nominal values, creates a first exposure component (e.g. diaphragm value or shutter speed) display whose value is related to predetermined exposure conditions, such as object brightness, film sensitivity and the other exposure component (e.g. shutter speed or diaphragm value). A second display section, comprising a second set of light display elements, also aligned with the nominal values, creates a second display of the exposure component chosen to be displayed. The second display represents the actual position of the camera element controlling the displayed exposure component.

摘要： An exposure meter circuit includes a photo diode 2 and associated components 1, 3-6 for producing a first logarithmically compressed voltage V.sub.1 proportional to the apex value B.sub.v of the sensed brightness level. The temperature characteristic of the transistor 1 coupled to the diode 2 is compensated for by developing a second logarithmically compressed voltage V.sub.2 and subtracting V.sub.1 from it in an operational amplifier 9. The voltage V.sub.2 is produced by a transistor 11 whose base is coupled to the cathode of a light emitting diode 13 and whose collector output is returned to the power supply through a diode wired transistor 12. The temperature characteristic of the LED is the same as that of a transistor, whereby compensation is realized.

摘要： A camera system includes a photographing lens having a lens memory and/or a lens controller, and a camera body including a body controller which can communicate with the lens memory and/or the lens controller; a first power and a second power which can be supplied to the photographing lens. The lens memory and the lens controller operate with the first power and the second power, respectively, when the photographing lens is mounted to the camera body. The body controller supplies the first power to the photographing lens to drive the lens memory to read data from the lens memory, and subsequently disables the lens memory and supplies the second power to the lens controller so that the body controller and the lens controller communicate with each other if the body controller determines, from the lens data, that the photographing lens includes the lens controller.

摘要： An image magnification control device for a camera. Control focal length required to maintain an image magnification constant is computed based upon defocus information detected by analyzing a light that passes through a photographic lens. In case a focal length of the photographic lens moves out of a range wherein the set image magnification can be obtained, various options, such as a shutter-release lock operation, can be executed depending upon the chosen design of the camera.
