PROBLEM TO BE SOLVED: To provide a good image quality even under a noisy environment considered by external noise in a mobile X-ray digital image photographing system carried to various environments and used. SOLUTION: This X-ray digital image photographing system is composed of a matrix sensor for detecting an X-ray image, a means for giving a photographing condition such as various exposures or the like to an X-ray generator, a PC for system control and a means for detecting external noise. The external noise is detected by the external noise detecting means before the exposure of X rays and the photographing condition applied to the X-ray generator is altered corresponding to the detection content of the external noise detecting means or the altered content is transmitted to the PC for system control to emit a warning so as to alter the photographing condition before exposure.
