| titleOfInvention | X-ray television camera device |
| abstract | (57) [Abstract] [Purpose] The present invention aims to simplify the circuit configuration of the light quantity adjustment controller to achieve high reliability and low price. In an X-ray television camera device for imaging a secondary phosphor screen of an image intensifier (hereinafter abbreviated as II) for converting an X-ray image into a visible image, an optical system and an image are picked up by a predetermined switching signal. A device for inserting and removing a neutral density filter mechanism having a predetermined brightness between the elements, and a gain control circuit for setting a video signal from the image sensor to a predetermined video signal level by the switching signal, This is an X-ray television camera device which is simple and inexpensive and which has a greatly improved reliability by adding a simple light amount adjustment controller and a switching type gain adjustment circuit to observe a fluoroscopic image at the time of film photographing. |
