Abstract: In the case of a device for the control of the shutter of a CCD camera supplied with preferably monochromatic light such as laser light from a light source, and more particularly for the control of the shutter of a CCD camera of a light ray marksmanship system, the CCD camera photographs dots of light produced by a firearm emitting a light ray directed on a reflecting screen or a television screen so that such dots may be evaluated by a computer and displayed. In order ensure that the CCD camera is essentially unaffected by interfering light sources and light from the surroundings, which has the effect of so-called "noise", and is able to respond to the main light ray, on the basis of a start signal the light source produces one or more light pulses and then a main pulse.
