Abstract

An X-ray based measuring device of the invention includes: X-ray imaging means (102, 103, 311) which have their detection areas divided into a plurality of detector units (102a to 102d, 201′), detect X-rays transmitted through an inspection object (106), and pick up X-ray images in interested areas (310, 902, 902′) of the inspection object; conversion means (211, 212) for converting analog image signals read from the detector units into digital image data under specified conversion conditions for each of the detector units; and re-conversion means (214, 222) for converting the digital image data obtained for each of the detector units under re-conversion conditions corresponding to the specified conversion conditions, wherein analog image signals are A/D converted into digital image data under optimum conversion conditions for each detector unit, and X-ray images in interested areas of the inspection object are sequentially picked up.
