摘要： A number of separate comparators compare respective analog inputs to a single reference waveform and turn off respective gates when the analog voltages achieve predetermined relationships to reference wave form. The gates pass pulses from a common source from the beginning of the reference wave form until the respective gates are shut off. In one version the analog signals represent photographic data such as diaphragm aperture and shutter speed in a camera, and are digitized for display within the camera.

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： An automatic exposure control apparatus for controlling the diaphragm of the camera in accordance with the preselected shutter time and the exposure value, in which a digital-to-analog converter having a counter responsive to the number of pulses supplied from a clock pulse generator through a gate produces a time variable output capable of attaining a certain level dependent upon the preselected shutter time and a light value as photoelectrically sensed, that is, an exposure value and, which is detected by a first comparator. The output of the first comparator is applied to the gate, so that the converter is set to memorize the exposure value therein. As the diaphragm presetting ring is moved from the maximum to minimum aperture position with production of a time variable output from a signal generator associated therewith, a second comparator responsive to the attainment of the time variable output of the signal generator to a level dependent upon the final output of the set converter produces an output which is applied to arresting means for the diaphragm presetting ring. This results in automatic adjustment of the position of the presetting ring. At the time the presetting ring begins to move, the diaphragm driving means is actuated causing the diaphragm means to be brought into engagement with the ring. Thus, an effective exposure aperture is established in the diaphragm means.

摘要： An apparatus for providing a digital display representative of photographic information which is visible in the viewfinder of a camera. Since the photographic information is comprised of a number of factors, a number of symbols or signs are displayed in association with the digital display so that the photographer can identify multidigit numbers displayed. The structure of the digital display is simplified by using an arrangement of connections between display and display driver which allows for further reduction in size of the camera.

摘要： The present invention relates to an exposure control system for a camera with both priority modes in which the photographic information of either the shutter time or the aperture value and the photographic information including the measured value of the brightness of the object to be photographed are processed so as to obtain a proper exposure value. The system is characterized in that either an optional shutter time or an optional aperture value is set by a common set means, for example, a dial in such a manner that the output of the set means is put in the operation means so as to control the exposure amount. Further, the condition showing whether the value set by the common set means is the aperture value or the shutter value is clearly indicated.
