ABSTRACT:
An exposure device controls the exposure of an image in a video camera using a vibration control system. The gain of an iris, which receives the image, the gain of an AGC amplifier, which amplifies the sensed image and the gain of an electronic shutter, which controls the speed at which images are sensed; are controlled by driving the iris in a first range indicative of an object illuminance when a hand vibration correcting operation is performed, driving the AGC amplifier in a second range indicative of the object illuminance, and driving the shutter in a third range indicative of the object illuminance.
