摘要： An automatic iris adjustment control for cameras which, using the APEX operational equations, compares the brightness value Bv and film sensitivity value Sv with the iris size indication value Av and shutter speed value Tv. The iris size indicating value Av is derived from the sum of pulses created by a pulse generator which operates in conjunction with the moving adjustment of the iris size. When the values are compared and found equal, an electro-magnet is de-energized stopping the movement of the adjustable iris at the correct iris setting.

摘要： An automatic exposure control device is disclosed which is capable of aperture dominant and shutter speed dominant exposure control operation as well as manual exposure control operation. A logarithmic compression circuit including transducers develops voltages directly dependent upon the APEX indicating quantities Bv, Sv, Tv and Av. For automatic operation one of the voltages dependent upon Tv or Av is set into the circuit by manual control, and the other is calculated by the APEX indication formula Bv + Sv = Tv + Av, and applied as an output to the shutter control or aperture control mechanism. An indicator means is connected in the circuit to provide Tv or Av indications depending on the exposure control mode selected for the camera.

摘要： An automatic exposure control device for a single lens reflex camera characterized in that a stop determining member which stops down diaphragm blades by rotation thereof at a predetermined speed is released by a shutter release plate. A time constant circuit is started to operate simultaneously with the start of rotation of said stop determining member, and the rotation of said stop determining member is stopped by an electromagnetic mechanism when a time has lapsed. The length of said time linearly corresponds to the stop size determined by APEX operation based on the output voltage of said time constant circuit as an operation factor.

摘要： A shutter speed digital display device for cameras equipped with both automatic and manual shutter speed controls is disclosed. A shutter speed display control circuit generates a first digital signal in accordance with the adjustment of the camera's shutter speed by an automatic shutter speed control circuit. The first digital signal is decoded and used to control a light-transmitting liquid crystal device display. In addition, when the camera is in a manual mode of operation, the first digital signal is compared with a second digital signal related to manually adjusted shutter speed. If the comparisons are equal, a coincidence indicator is energized.

摘要： A light meter circuit for an SLR camera implements full aperture viewfinding with a preselected exposure time by providing an integrating capacitor 25 for controlling the exposure time, a first switch 24 for enabling the charging of the capacitor, circuit means 26, 29 for controlling the charging of the capacitor, a variable resistor 30 for establishing the lens aperture value in an exposure time display mode, a fixed resistor 31 for establishing the aperture value in an exposure time control mode, and a second switch 32 for connecting one of the resistors to an input of the charging control circuit. When the shutter release button is depressed the second switch is transferred from the variable to the fixed resistor, and the first switch is subsequently opened to enable the charging of the capacitor.
