Abstract
In an X-ray cinecamera apparatus with a TV camera, an X-ray tube for radiating X-rays to subject and cinecamera are operated by a controller in a desired timing differing from TV synchronous signals. After video signals output from a TV camera during an odd field period (or even field period) are written into field memory, both the video signals stored in field memory and the video signals output from TV camera during a continued even field period (or continued odd field period) are processed by the adder to a desired brightness level. As a result, flickerless X-ray dynamic images can be displayed on TV monitor.
