<P>PROBLEM TO BE SOLVED: To evaluate possibility that each part of an endoscope image is a lesion part, based on information except color of the endoscope image. <P>SOLUTION: In step S100, a ratio G/R of a pixel value G to a pixel value R is obtained from an RGB signal of each pixel, and the possibility that a target pixel is the lesion part is evaluated from color information related to the absorption band of blood. In parallel therewith, in step S102, a luminance signal of a prescribed space frequency area is extracted from a luminance signal of the image. In step S104, information related to a surface structure of an intestinal tract or the like such as a gyrate pattern is decided based on the extracted luminance signal, and the possibility that the target pixel is the lesion part is evaluated. Based on the evaluation of the steps S100, S104, in step S106, the possibility that the target pixel is the lesion part is integrally evaluated, and an image indicating a risk degree of each portion is generated based on the evaluation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
