ABSTRACT:
Disclosed are a method and apparatus for determining the deviation of an image from a predetermined position on a kinescope screen. This method and apparatus is useful, for example, in centering an image on the screen. The scan lines of the kinescope are divided into a series of pulses. The pulses within the image on each side of a reference line or X-Y coordinate system are counted and compared. The ratio of the pulses is an indication of the area of the image on each side, and suitable adjustments may be made in the position of the image to center it with respect to the reference line.
