ABSTRACT:
A video tracking system including a processor unit for adaptive gating and processing video output signals from a television camera to form computing signals therefrom. The time duration of the computing signals is representative of the duration of corresponding increments of area of a selected target image, and their amplitude is an inverse function of the total image area. The computing signals are further processed within a pair of error detector channels, each having a plurality of integrators interconnected by gating circuits controlled by fixed time duration computing gates, to form output signals representative of the relative angular position of the centroid of the image.
