ABSTRACT:
A microfilm camera uses an instant imaging film, such as a vesicular film. Simultaneously with the exposure of the film, a small blip is recorded along the length of the film. On readout, the camera may be set to count the number of blips and thereby stop a searching reader at a preselected frame. The invention is primarily directed to a circuit for controlling the recording of the microfilm images and the blips on such instant imaging or vesicular film.
