ABSTRACT:
A light flash control apparatus is used for an endoscope in which a solid-state image sensor is employed. A image signal derived from the solid-state image sensor during the illumination by a halogen lamp is also utilized as a photo-metric signal. An adequate quantity of flashlight for the image sensor is calculated in advance based upon the photo-metric signal. The calculated exposure time i.e., the desirable quantity of flashlight is stored in an integration circuit. After the given exposure time passes since the flash tube is ignited, it is forcibly turned-off by a turn-off thyristor.
