Abstract

PURPOSE: To permit the observation of image all the time by suppressing halation produced in television monitor during photographing period by approximating image signal level during photographing period to the level during clairvoyance period.
CONSTITUTION: A voltage proportional to tube voltage to be applied to X-ray tube is extracted from the extraction circuit 21, and then applied to the automatic exposure control circuit 23 and the partial pressure circuit 22. During clairvoyance period, the automatic exposure control circuit 23 is not operated and a voltage corresponding to tube current is extracted from the tube current extraction circuit 24 through the sliding terminal 24A. When making photographing, the automatic exposure control circuit 23 is operated and an output signal by which the proper exposure amount of film is reached is applied as a target voltage to the photographing tube inside the camera head 30.
