    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 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.

    摘要: At the side of the camera body, switches for treating the totally opened F value information of the photographic lens as coded digital information of a certain determined number of bits are connected to the digital exposure operation circuit. At the side of each of the photographic lens which is made interchangeable for the camera body, a signal pin is arranged for indicating the totally opened F value proper to the photographic lens as coded digital information of the above mentioned determined number of bits in such a manner that at the time of mounting the photographic lens on the camera body, the switches at the side of the camera body are closed in selected combination in accordance with the totally opened F value of the lens. Accordingly the totally opened F value of the photographic lens is put into the digital exposure operation circuit.
