ABSTRACT:
An exposure adjustment apparatus determines, based on the level of a signal of an object converted by a solid state image sensing device, whether the exposure time or the gain is to be decreased, increased or maintained, and controls the gain of an amplifier and the drive pulse to be generated by a drive pulse generator. Thereby, the output signal level is adjusted by controlling only the exposure time of the solid state image sensing device and the gain of the video signal resulting in a compact and vibration-resistant exposure control system which is inexpensive.
