ABSTRACT:
An X-ray radiographic apparatus has an electronic shutter circuit operable at a photographing time to vary time for storing electric charges in a CCD image pickup device. This avoids saturation of the CCD image pickup device due to an increased quantity of X-rays. Further, an image outputted from the CCD image pickup device is latched at the photographing time for improved durability and responsibility. A photographed image may be observed on a monitor unit also after photo taking.
