Claim:
1. An image processing device, that executes an image processing on an original image incorporating a metal piece obtained by the radiation imaging of a subject having an implanted metal piece inside, comprises: a standard deviation image generation module operative to generate a standard deviation image, wherein the standard deviation is mapped relative to the pixels constituting said original image by repeating an operation to calculate the standard deviation of the pixel values of an attention pixel of said original image and the periphery of said attention pixel while changing said attention pixel; an image calculation module operative to generate a calculation image by addition or subtraction between said original image and said standard deviation image; a calculation image binarization module operative to generate the binarization calculation image by binarization of said calculation image; a graph cut processing module that is operative to comprehend the distribution of the metal piece on the original image based on said binarization calculation image, obtain the representative value of pixel values of the metal piece region of said original image and the representative value of pixel values of the region other than the metal piece, and generate a map showing the distribution of the metal piece relative to said original image by execution of the graph cut processing on said original image referring to each representative value.
