PROBLEM TO BE SOLVED: To provide a diagnosis support device that facilitates grasping a difference in a disease region to perform highly accurate diagnosis support, and to provide a method for processing an image on a diagnosis support device and a program.SOLUTION: A method for processing an image on a diagnosis support device for diagnosing a lesion from an imaged picture includes a step (A) for processing an image of an imaged picture. The step (A) includes setting a peripheral region except for a diagnosed region having a high-probability of disease of the imaged picture, as a measurement region, in performing image correction.SELECTED DRAWING: Figure 1
