FREEZE FRAME APPARATUS FOR MOVING MAP DISPLAY SYSTEM ABSTRACT OF THE DISCLOSURE Apparatus for use with a moving map display system for freezing the moving map at a predeter- mined position. Analog video signals corresponding to the predetermined map position are digitized and stored in memory. The digitized signals are re- trieved and converted back to video signals for continuous display during the freezing function. The moving map display system returns to normal operation upon completion of said function. A built in test capability is implemented by switching in a fixed signal, converting and storing, and then verifying said signal in memory.
