Abstract
AN X-ray imaging apparatus includes an image intensifier for converting an X-ray passing through an object to be examined into an optical image, a solid-state image sensor for converting the optical image into a video signal, a monitor for displaying the video signal, and an X-ray photographing apparatus for picking up an X-ray image. When a photographing mode is selected, the solid-state image sensor receives two transfer pulses during a vertical blanking period to reduce the luminance of the video signal. Electric charges stored in electric charge storage areas in the solid-state image sensor are externally discharged in response to the first transfer pulse, and the electric charges stored after the discharge are read as the video signal in response to the second transfer pulse.
