<P>PROBLEM TO BE SOLVED: To accurately detect an abnormal portion having a pixel value different from neighboring pixels. <P>SOLUTION: In an image processing apparatus 10, a computing unit 20 includes an approximate value calculating unit 21 that calculates an approximate value that becomes consecutive inside an examination area for a pixel value of each pixel of the examination area based on the pixel value inside an image, a validity evaluating unit 22 that evaluates whether the approximate value is valid on the pixel value, an area dividing unit 23 that divides the examination area with the approximate value that is evaluated as being invalid, an examination area re-setting unit 24 that sets each divided area obtained by the area dividing unit as a new examination area and controls a repetition of processing, and an abnormal portion detecting unit 25 that detects an abnormal portion based on the pixel value inside the image and the approximate value that has been evaluated as being valid by the validity evaluating unit 22. <P>COPYRIGHT: (C)2012,JPO&INPIT |
