Abstract

PURPOSE:To increase the tracking speed, by picking up a plurality of video element trains located radially from the center of screen, calculating the correlation as to the video elements at the location corresponding respecively to the new and old pictures individually, and obtaining the video element train and the position shift of the new and old pictures in which the correlation is maximum. CONSTITUTION:A video singl 3 obtained by picking up a tracking objective 1 with a camera 2 is transmitted to a signal processor 4. In this processor 4, the movement within the screen of the preset objective 1 is detected and it is inputted to a drive servo system 6. In this case, as to the video element train positioned radially from the center of a search area 9 on a TV screen 7, the correlation between the old and new pictures is calculated respectively, and the video element train and the shift between the old and new pictures at the video element train are detected when the maximum correlation is obtained. Thus, the objective 1 is always at a given position within a screen by correcting the direction of a camera 2.
