Abstract

PURPOSE: To detect the speed of moving objects by providing a function of adjusting shutter time by the moving speed signal of the subject contained in reflected waves.
CONSTITUTION: The signals outputted from a detection circuit 6 are amplified by a deviation frequency amplifier 7 and the levels thereof are discriminated in a frequency discrimination circuit 8, which in turn outputs the set signal for shutter time. An exposure meter 9 outputs the signal concerning the quantity of light to an exposure setting mechanism 10. The exposure setting mechanism 10 determism the optimum exposure after determining the shutter time by giving priority to the output of the frequency discriminator 8 and outputs the signal thereof, thereby adjusting shutter time mechanism 12 and aperture mechanism 13. When the photographer pushes the shutter, the preset optimum shutter time and aperture photography may be performed
