Abstract

PURPOSE: To obtain sufficient contrast resolution by providing a lst image pickup means picking up a picture with a low gain and a 2nd image pickup means picking up a picture with a high gain sequentially at each prescribed timing and synthesizing each picture picked up by both the image pickup means so as to reconstitute the picture as one picture.
CONSTITUTION: An X-ray tube 1 is controlled by an X-ray generator 10. A camera output corresponding to a short X-ray exposure time 1 is read as a low gain picture (lst L picture : VIEW1). Succeedingly a camera output corresponding to a long X-ray exposure time t. is read as a high gain picture (lst H picture : VIEW1). Similarly, VIEW2 and succeeding pictures are repeated. Thus, the pictures of high and low gain are picked up by controlling the X-ray exposure time and the pictures are synthesized and reconstituted into one picture, then the dynamic range of a television camera is widened. Thus, sufficient contrast resolution is obtained.
