Abstract
An apparatus for altering the position of a video image, such as an image produced by a video camera, video tape recorder or other image producing device utilizing a raster type scan, without rescanning of the originally generated image alters, by a precise amount, the phase of a video camera or playback device with relation to the overall system or plant sync, while maintaining exact sync timing relationships for all timing pulses fed to the video camera or playback device. The video from the camera or playback device is processed so as to restore its blanking and sync timing to match the timing of other video sources within the system. The horizontal and vertical sync pulses fed to the camera or playback device, such as a video tape recorder, which generates the original image or raster have their phase shifted to accomplish movement of the original image by generating the horizontal and vertical sync pulses from a color subcarrier while keeping phase lock to the sub carrier with the phase shifted sync being reinserted in the picture portion of the original picture signal while the original picture sync is deleted and made to look like a picture signal. This phase shifted sync effectively moves the picture to the left or right or up or down to reposition the image.
