Abstract

A photographic recording device which records a succession of related pictures on a film, such as a movie camera or a microfilm recorder, is arranged to photograph images successively displayed on a computer graphics terminal. The film advance motor of the recording device is controlled by a circuit in the terminal ordinarily used for operating a bell to signal computer programming errors, the bell circuit being modified in this instance so that it causes the film to advance automatically under program control as each picture is taken.

Generating Movies or Similar Pictures From Images Displayed on a Graphics Terminal

A photographic recording device which records a succession of related pictures on a film, such as a movie camera or a microfilm recorder, is arranged to photograph images successively displayed on a computer graphics terminal. The film advance motor of the recording device is controlled by a circuit in the terminal ordinarily used for operating a bell to signal computer programming errors, the bell circuit being modified in this instance so that it causes the film to advance automatically under program control as each picture is taken.

The present technique dispenses with the need to use a special photographic recording apparatus having a built-in display device, which in practice has been found unsatisfactory for high-volume usage. The arrangements illustrated herein employ a conventional movie camera and a standard graphics terminal equipped with a bell circuit. Fig. 1 shows one such arrangement. The display is of the storage scope type. The bell circuit is tapped to a relay which operates the film- advance motor of the camera whenever a bell operating signal is generated by the software. The computer program is written in such manner that a bell operating signal is generated whenever a new picture is to be taken. The bell may be disconnected, or, alternatively, it may be left in the circuit, to provide audible signals which indicate that the camera is working. The program error ...
