Correlatively tracking unit

Abstract

Abstract PURPOSE:To cancel the tracking delay of servo system and to enavle to held the scene or objective at a given position of screen, by giving suitable delay time to the horizontal and vertical synchronizing signals and superimposing then on video signal. CONSTITUTION:After the composite video signal from the television camera 1 is separated into video signal, vertical and horizontal synchronizing signal through the synchronizing separation circuit 17, the synchronizing signal only is fed to the vertical and horizontal synchronizing signal delay circuits 18, 19. After adjusting the delay time according to the measurement value of tracking delay, it is input to the composite video signal synthesis circuit 20, it is superimposed on the video signal of the next screen to produce the composite video signal. In this case, when the composite video signal is fed and displayed to the television monitor 11, the objective and the vertical and horizontal correlativity area set by surrounding the objective can be standstill at the specified position on the screen.
