PROBLEM TO BE SOLVED: To correct read image data with high precision corresponding to pixel size at the read-out time by correcting the read data with the correction data corresponding to the read pixel size when a radiation image is read. SOLUTION: A correction data generating means 17 generates horizontal scanning correction data, polygon correction data, and vertical scanning correction data with plural read pixel sizes and stores them in memories 18, 181, and 19 respectively. An interpolation data generating means 21 generate two-dimensional correction data with plural read pixel sizes. Then a correcting means 24 selects the correction data corresponding to the read pixel size of a radiation image obtained by photographing a subject 2 among the correction data that are obtained from the memories 18, 181, and 19 and the interpolation data generating means 21 and correspond to the read pixel sizes and used to correct an image signal at the read-out time. Consequently, excellent corrections can be made irrelevantly to the pixel size. |
