摘要: A rear light condition detecting device for a camera is arranged to measure distances to a plurality of parts appearing within a taking picture plane on the assumption that an object located nearby is the main object to be photographed or that a light source such as the sun is among faraway objects. The device determines the object to be in a rear-light or counter-light condition in cases where the luminance of the nearby object is extremely lower than other objects or that of a faraway object is extremely higher than other objects.

摘要: A distance detecting device comprising radiation projecting means for projecting a radiation beam; radiation sensing means which is disposed away from the radiation projecting means with a given length and is arranged to receive a reflected radiation beam coming from an object whose distance is to be detected as the radiation beam is projected from the projecting means; and movable means for relatively varying the incident condition of the projected radiation beam onto the sensing means. The distance to the object is found either by the position of the movable means or by the amount of displacement thereof which occurs at a time point at which the sensing means optimally receive the reflected radiation beam coming from the object in the process of relatively varying the incident condition of the projected radiation beam onto the sensing means. In the incident condition varying process, the output signal of the sensing means and a delayed signal which is obtained by delaying the output signal a predetermined period of time are compared with each other to detect a time point at which the output signal of the sensing means has reached its peak level and, accordingly, to detect when the sensing means optimally recieve the reflected radiation beam coming from the object.

摘要: A camera having a focus detecting device for automatically detecting a condition of sharpest focus. According to an improvement of the invention, when the brightness level of an object of principal photographic interest becomes so low as not to permit satisfactory operation of the focus detecting device, or when the actual voltage of a battery falls below a satisfactory operating level for the device, a supplementary device can be rendered operative to control setting of a photo-taking lens independently of the focus detecting device, thereby the camera can be focused at an appropriate distance depending upon the size of diaphragm aperture, namely, in a pan-focus position.According to a further improvement of the invention, an exposure control apparatus in the camera is made associated with the aforesaid two devices in a manner to be rendered operative in response to an accomplishment of setting the taking lens.

摘要: A camera having an automatic focus adjusting device with an arrangement that permits manual focus adjustment by moving a focus adjusting member to a desired position by means of an operation member when automatic focusing is impossible. The camera includes an automatic focus detecting circuit including a photoelectric light sensor, a photographic lens and a focus adjusting member for holding the photographic lens. The member is movable within a certain determined range for focusing by means of a spring. A latch device for latching the focus adjusting member in a focus adjustment start position is included. The latch device is arranged to release the focus adjusting member from the state of being latched to cause the focus adjusting member to start automatic focusing in response to a shutter release operation. A stop is arranged for stopping the focus adjusting member at the in-focus position in response to the output of the automatic focus detecting circuit. An operation member is provided for adjusting the stop position of the focus adjusting member. Finally, a change-over device is included for releasing the latch device irrespective of the shutter release operation of the camera. The change-over device is shiftable between an automatic focus adjusting position and a manual focus adjusting position.

摘要: A camera is provided that has an automatic focus detector and a manually operable focus adjustment device, in which the focus adjustment device can be set at a predetermined position or range falling outside of an ordinary focus adjusting range. At the same time a coordinating device is provided which functions to secure an appropriate depth of field (or a hyper focal range) by coordinating the focus adjustment and the exposure aperture adjustment when the focus adjustment device is set at the predetermined position or range. Thus even in a case when the focus detector can not function effectively, practically satisfactory photographing can be done by the action of the coordinating device.In a preferred example of the present invention the focusing condition of a photo-taking lens system is automatically adjusted according to an exposure aperture value (i.e. f-stop value) by the action of the coordinating device in a condition in which the focus adjustment device is set at the predetermined position.In another preferred example of the present invention, the size of the exposure aperture is automatically limited to a predetermined aperture size or smaller according to the set position of the lens system by the action of the coordinating device in a condition in which the focus adjustable device is set at a predetermined position or range.
