ABSTRACT:
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.
