Abstract
A color television or video system for processing signals from a television camera, in which a number of different signals corresponding to images of different colors give rise to different color partial images superimposed on the television screen to form a single full color image. The signals are processed so that the partial images superimposed on the screen correspond to images seen by the camera at time separated by predetermined intervals, so that the partial images of an object moving relative to the camera are displaced relative to one another on the television screen to give a stereoscopic effect when the different images are presented to different eyes of the viewer. To give an optimum effect, the displacement of the partial images should be in a direction appropriate to the direction of horizontal movement in the screen. The signals are processed so that, at least over a number of successive fields, the full color images on the television screen include images in which the displacement between different color partial images, or parts thereof, is in a direction appropriate to the predominant horizontal direction of movement in the scene. In one embodiment, the signals are…
