A vacuum box, having a pair of soft X-ray windows for passing a soft X-ray generated by a soft X-ray source therethrough, is disposed in front of the soft X-ray source. A face plate for a color CRT is disposed at a rear side of the vacuum box. A color camera is arranged so as to observe a light emitting sate of an RGB phosphor screen of the face plate for the color CRT at a time where the soft X-ray generated from the soft X-ray source is irradiated on the face plate for the color CRT through the vacuum box. An image processing unit analyzes a color picture obtained from the color camera.
