Abstract : This invention relates to automatic exposure control for an image-intensification photographic camera through the employment of a capacitor discharge circuit. The electrical energy stored in a capacitor is discharged to activate an image intensifier tube which forms part of the photographic camera system. The characteristics of the capacitor discharge circuit are chosen to correspond to the energy required for proper exposure time through the image intensifier tube and onto a photographic emulsion.
