PROBLEM TO BE SOLVED: To erase an unnecessary area in an image without leaving its trace. SOLUTION: Area calculated according to an unnecessary area is compared with preset area (for example, 100 pixels) (S3: area comparison). When the calculated area is less than preset area, an isotropic diffusion equation and an anisotropic equation are used in combination (S4: isotropic diffusion equation/anisotropic diffusion equation). Meanwhile, when the calculated area is not less than the preset area, an advection equation and a Navier-Stokes equation are used in combination (S5: advection equation/Navier-Stokes equation).
