Abstract
A synthetic motion generator system including a TV camera positioned to rrd a still life scene and a TV monitor connected to receive video signals from the TV camera and in which the vertical and/or horizontal sweep input to the camera is modulated by apparatus including a tuneable oscillator, a sawtooth generator and logic converter and sample and hold circuitry to provide to the camera sweep circuit a modulating signal which is a multiple of the television frame rate, plus or minus a few cycles per second, to thereby generate desired motion in the monitor display image. The invention is particularly applicable to the generation of sea wave motion from a still seascape scene and in this environment the invention includes not only the development of wave motion, but of speed and amplitude control as well as apparent direction variation. These functions are obtained through the medium of frequency and amplitude adjustment on the oscillator equipment and the provision of an input potentiometer and wiper arms connected to the oscillators to coordinately frequency vary the same to produce the desired wave function in association with the direction of a periscope operating the wiper arms.
