The effects of video frame rate upon target acquisition range and acquisition probability was examined at frame rates of 24, 8, 3, and 1 frame/second. Motion picture imagery played through a TV system was used: 16mm film of a terrain board and 35mm of real terrain. Skipframe printing of the film permitted frame rate variation. The terrain board film simulated a speed of Mach .80, while the real terrain film simulated Mach .95. Observer slewing of the scene via joystick control was possible on the natural terrain film. Ten observers were used on each of the 8 conditions. Target acquisition range and acquisition probability did not vary in a statistically significant manner with frame rate. It was concluded that, in the absence of appreciable video noise, slow frame rates are adequate for target acquisition of briefed targets. For drone aircraft this leads to greatly reduced TV bandwidth, a big advantage.
