<P>PROBLEM TO BE SOLVED: To improve the detection of the existing position of intraluminal abnormal tissue. <P>SOLUTION: A CPU performs gray scale value gradient calculation processing for R signals for instance in a step S10, performs isotropic change feature amount calculation processing from the calculated gray scale value gradient in a step S11, and performs polyp candidate detection processing of generating a polyp candidate image 26 at the existing position of a polyp from the calculated isotropic change feature amount in a step S12 further. <P>COPYRIGHT: (C)2007,JPO&INPIT |
