Workpiece alignment system

A system for permitting alignment between a movable gun and a desired target, comprising in combination:

• an electronic scene observing first means mounted for movement with said gun for viewing a scene nominally centered about whatever said gun is pointing toward;
• an electronic scene displaying second means for displaying to an operator a portion less than all of whatever scene is observed by said first means, said second means also including a control terminal receptive of a control signal for determining which portion of the viewed scene is to be displayed;
• third means coupled to said gun for producing a first signal indicative of the actual rate of movement of said gun;
• a control handle fourth means producing a second signal corresponding to the desired rate of movement of said gun;
• and
• fifth means responsive to said first signal and second signal for producing said control signal for causing said viewed image to move only at a rate set by said fourth means whereby when said fourth means is set to indicate a zero rate of movement of said first means the displayed image is stationary even though said first means may be in motion.
