Claim Text:
1. A contour correction device that corrects, for contour lines of two adjacent regions in which a part of the contour line displayed on a display screen is shared, one of the contour lines bisected by a correction contour line of one of the two regions, so that a set correction contour line becomes a part of the contour line of the one region after correction, in response to an input to set the correction contour line in which two different points on the contour line of the one region are a start point and an end point, inside the one region from an operator using input unit for designating an arbitrary position in the display screen, the contour correction device comprising: determination unit for determining whether the start point and the end point are located on a shared contour line that is the contour line shared by the two regions or on a unique contour line that is a contour line other than the shared contour line; and contour correction unit for maintaining the contour line of the other region when correcting the contour line of the one region so that the correction contour line becomes a unique contour line in the contour line of the one region after correction, and a part that is the shared contour line of the contour line of the one region to be corrected becomes a unique contour line in the contour line of the other region after correction if it is determined that the start point is located on the unique contour line and the end point is located on the shared contour, and correcting the contour line of the other region so that the correction contour line becomes a shared contour line in the contour lines of the two regions after correction rather than the part that is a shared contour line of the contour line of the one region to be corrected when correcting the contour line of the one region, if it is determined that the start point is located on the shared contour line and the end point is located on the unique contour.
