PROBLEM TO BE SOLVED: To provide an X-ray photography capable of displaying corresponding points in the right and left to respectively have equal brightness in imaging a subject which includes very small areas having equal tissue structures or with an equal X-ray transmittance at the symmetrical positions. SOLUTION: An exposure time deriving part 8 obtains the time of exposure in the subject 1 with an X-ray in a process to generate each charge signal which is outputted from an X-ray image detecting part 3, based on vertical transfer information held by a vertical transfer information holding part 5. A correction coefficient deriving part 9 obtains a correction coefficient for correcting the value of an image signal which is obtained by conversion from each charge signal, based on the exposure time. An image generating part 10 generates the image signal from the correction coefficient and the charge signal which is outputted from the X-ray image detecting part. COPYRIGHT: (C)2006,JPO&NCIPI
