Abstract
A radiographic device includes grid frequency component eliminating processing means for eliminating a grid frequency component from an original image detected by a radiation detecting device; wherein said means includes a BPF and an HPF for producing a band-pass grid image and a high-pass grid image from an original image through band-pass and high-pass extraction; a subtracting device for taking the difference between these two grid images; an LPF for producing a difference grid image comprising the grid frequency components not completely extracted by the band-pass, through performing a low-pass processed on the difference image in a direction that is parallel to the grid pattern; an adding device for producing a band-pass+difference grid image by adding the difference grid image to the band-pass grid image; and a subtracting device for subtracting the band-pass+difference grid image from the original image.
