PROBLEM TO BE SOLVED: To provide a X-ray radiographic apparatus capable of performing frequency processing, e.g. smoothing (noise removal) and sharpening (edge enhancement), appropriately depending on the distribution of resolution occurring in the photographing region of a photographing means due to bubbles in the production process and ensuring good diagnostic power. SOLUTION: The X-ray radiographic apparatus comprises a photographing means outputting radiographic image data of an object, a first memory for storing the image data from the photographing means, a means for detecting resolution distribution of the photographing means, a second memory for storing the resolution distribution detected by the resolution detecting means, and an image processing means performing frequency processing of the image data stored in the first memory at an intensity dependent on the resolution distribution stored in the second memory.
