X-RAY FLUOROSCOPIC DEVICE

PURPOSE: To facilitate operations on the occasion of accurately examining the interest area of a testee by obtaining the range of a X-ray fluoroscopic image formed by X-rays passing through the interest area, enlarging the image formed by video signals by an enlargement ratio which makes the range of the fluoroscopic image maximum in a monitoring area, and thereby making it a X-ray fluoroscopic image. CONSTITUTION: A image processing means 200 includes an A/D converter 230 converting video signals from a television camera 124 into digital video signals, an D/A converter 24O converting digital video signals from an image processing section 220 into analogue video signals, and also the image processing section 220 and an operation circuit section 210. The image processing section 220 holds the digital video signals from the A/D converter 230 in a video memory, concurrently operates the digital video signals by a command from the operation circuit 210, processes them in image, and outputs them to the D/A converter 240. And as one of image processing, the image formed by the digital video signals is enlarged/contracted in response to a command from the operation circuit section 210.
