- 摘要：
PROBLEM TO BE SOLVED: To provide an X-ray image photographing device which is capable of removing density unevenness like a stripe which occurs in a random place of an image and has a relatively narrow width and a large amplitude.
SOLUTION: An image processor includes: a first filter processing unit which performs filter processing on an original image including a photographed subject and density unevenness like a stripe extending in a first direction, in a second direction orthogonal to the first direction to generate a first image from which a high frequency component is extracted a threshold determination unit which performs threshold determination on the first image in the second direction to generate a second image from which pixels having pixel values smaller than a threshold are removed a second filter processing unit which performs filter processing on the second image in the first direction to generate a third image from which a low frequency component is extracted and a subtraction unit which subtracts the third image from the original image to generate an image in which the density unevenness like a stripe included in the original image is corrected.
