Claim One:
1. An image processing apparatus comprising: a hemorrhage edge candidate area extraction section for extracting a candidate area for the outline part of a hemorrhage area, based on an image signal of a medical image constituted by multiple color signals obtained by capturing an image of a living body; a feature quantity calculation section for calculating a feature quantity of the hemorrhage area based on calculation of a value of the amount of change in the image signal in a small area including the candidate area, among multiple small areas obtained by dividing the medical image, the value of the amount of change indicating that a luminance value of at least one of the color signals in the small area changes most largely; and a hemorrhage edge determination section for determining whether or not the candidate area is a hemorrhage edge as the outline part of the hemorrhage area, the hemorrhage edge determination section comprising a shape edge determination section for determining whether or not the candidate area is a shape edge as an outline part of a mucous membrane shape area based on the feature quantity, and an edge determination section for determining whether or not the candidate area is the outline part of the hemorrhage area by excluding the shape edge.
