A radiation area extracting method for extracting a radiation area from image data includes a generating step of generating combinations of at least two candidate lines from an area of the image data, an evaluating step of obtaining evaluated values of the combinations of at least two candidate lines, and an extracting step of extracting one of the combinations of at least two candidate lines as a contour line of the radiation area on the basis of the evaluated values. |
