24 May 1974TL;DR: In this article, an image generated by a television camera is combined with an image from digitally stored information to form a composite scene wherein objects appearing in either image properly occlude one another with respect to the eyepoint from which the scene is viewed.
Abstract: An image generated by a television camera is combined with an image generated from digitally stored information to form a composite scene wherein objects appearing in either image properly occlude one another with respect to the eyepoint from which the scene is viewed. This is accomplished by processing the camera video signal to provide pulses for each raster line which indicate the starting and stopping points of an object viewed by the camera. At the same time, the camera video signal is provided on a delay line to a video switch which also receives the digitally generated video signal. The switch is controlled by logic circuitry in accordance with the established occlusion priority to pass to the video display device the proper signal from either the camera or the image generator.

Abstract: A portable battery operated color television camera is provided with a switch system for use to preserve power while testing the camera and associated equipment or while engaged in standby operation. The switch system removes the power from two of the three pickup tubes in the camera, thereby reducing power consumption while allowing testing or standby operation in a black-and-white mode.
