The present invention relates to an automatic exposure adjusting device for a camera or the like, comprising a single photometric mechanism capable of measuring the light corresponding to the light amount entering into a photosensitive material such as film, the first light amount control mechanism driven in accordance with the output of the photometric mechanism for controlling the light amount over the range of the ordinary brightness and the second light amount control mechanism capable of operating in accordance with the output of the photometric mechanism beyond the operation range of the first light amount control mechanism, whereby for the brightness of the object beyond the range of the ordinary brightness the second light amount control mechanism is automatically operated in accordance with the output of the photometric mechanism so as to give a proper exposure.
Control and regulation apparatus 16 for the control of the exposure and transport speed of a motion picture film with a motion picture camera whose film transport motor 26 is connected to a speed control apparatus 23 and which has a rotary shutter which can be adjusted by means of a servomotor 3 and which is connected to a potentiometer 6 as a position sensor. A setpoint for the shutter aperture of the adjustable rotary shutter is specified as a function of the current film transport speed by the control and regulation apparatus 16 via a converter 14 to a position controller 13, whereby the product of the film transport speed and the shutter aperture is always a constant value. Different film transport speeds, shutter apertures and transition times can be input to the camera in a programmer apparatus 19 or in a remote control apparatus 181, 182, and initiated sequentially by means of a program key 183.
