Apparatus and method for positioning an article utilizes a video signal of the article from a television camera to accurately position the article. Vertical and horizontal sync signals from the camera are used to generate first and second boundary markers to provide +/-X and +/-Y positioning, respectively. Sensitivity markers are also generated to monitor system sensitivity in non-object areas. The magnitude of the coincidence between the article and the boundary markers is utilized to control the motion of the positioning adjustment.
