    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 photographing information display circuit for a camera which performs digital computation of information relative to exposure, etc. and displays the computed digital values. The display of the digital value computed is effected through an analog display circuit such as a meter circuit by an extremely simplified circuit arrangement, without using any D-A conversion circuit such as a ladder circuit or the like. The invented display circuit arrangement minimizes the electric power requirement for display to solve the problem of electric power consumption for display in small-sized 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.
