<p><P>PROBLEM TO BE SOLVED: To reduce a load, a power consumption, and a heating value of a light source for irradiating light aimed at reset of a conversion element, and to suppress deterioration progression of the conversion element. <P>SOLUTION: An apparatus includes a plane detector 120 constituted by including a plurality of pixels having conversion elements, for acquiring a radiographic image, based on a radiation 111b transmitted through a subject 300; the light source 130 for irradiating light having a wavelength band detectable by the conversion element to the conversion element; and a control part 150 for detecting a reference value from an offset image photographed, without having to use radiation prior to photographing a radiographic image, and irradiating from a light source 130, light for putting the conversion element into a saturated state based on the reference value. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
