    摘要: In the disclosed focus adjusting device, at least part of an image forming optical system and a focus adjusting mechanism is arranged within a housing attachable to and detachable from a camera body. A focus condition detector includes a photo-sensor disposed on a plane corresponding to the camera image plane, an electrical detection circuit connected to the photo-sensor, and a detecting optical system for forming an image of at least a part of the object on the surface of the photo-sensor. An aural indicator emits a sound to inform a photographer of the condition of the image formed on the surface of the predetermined focal plane as determined by the focusing condition detector.

    摘要: In the disclosed camera, an exposure value determining arrangement produces an electrical signal in response to a light measuring facility and a film sensitivity setting device. An exposure factor unit determines a combination of shutter speed and aperture value for a proper exposure in response to the exposure value determining arrangement. A control connected to the exposure factor unit varies the combination of exposure factors in the exposure factor unit in response to the set position of a program constant setting arrangement which is set for a particular program constant.

    摘要: In the camera disclosed, depending upon whether the shutter preference or aperture preference mode is selected, a computer establishes a computed value on the basis of a preset value and other ambient conditions. A number of separate comparators compare the respective values to a single reference wave form and turn off respective gates when the analog voltages achieve predetermined relationships to the reference wave form. The gates passed pulses from a common source from the beginning of the reference wave form until the respective gates are shut off. The values are thus digitized and displayed within the camera.

    摘要: A conversion system for a camera of a type controlled through computation of digital information. The system converts a coded digital value into a digital value of another coding. The code which comprises a gray code representing an integer part of the value and a code pattern representing a decimal part of the value is converted in such a manner that: The integer part is converted into a binary code while the decimal part is converted into a code to which a weight of 1/2, 1/4 or 1/8 is applied. With such a method of conversion employed, values set at 1/3 increment or decrement steps such as ASA film sensitivity values are readily converted into binary codes to facilitate the computing operation of the camera.

    摘要: An apparatus for setting an exposure control factor into a camera in the form of a digital signal without using a code plate or a plurality of switches. A pulse train is fed to a binary counter through an AND circuit which, upon selective receipt of gating-on and gating-off signals, operates to initiate and terminate flow of pulses therethrough respectively. When the counter has counted the selected number of pulses, the photographer who is viewing a digital display unit cooperative with the counter to detect this pulse number may actuate a button to produce the gating-off signal, thereby a corresponding desired value of the exposure control factor is set into the camera as a function of the number of pulses counted.
