摘要：
PROBLEM TO BE SOLVED: To provide an image processing apparatus or the like capable of performing high-accuracy detection of an abnormal region that shows a pixel values change that is different from those in the surroundings.SOLUTION: The image processing apparatus includes: an approximate-surface calculator 16 that calculates multiple approximate surfaces that each approximate the pixel value of a pixel included in an examination-target region of an image an approximate-surface selector 17 that selects at least one approximate surface from the approximate surfaces on the basis of the relation between the pixel value of the pixel in the examination-target region and the approximate surfaces an approximate-region setting unit 18 that sets an approximate region that is approximated by at least the selected one approximate surface and an abnormal-region detector 20 that detects an abnormal region on the basis of the pixel value of a pixel in the approximate region and the value corresponding to the coordinates of that pixel on at least one approximate surface.COPYRIGHT: (C)2013,JPO&INPIT【課題】周囲とは異なる画素値変化を示す異常部を精度良く検出することができる画像処理装置等を提供する。【解決手段】画像処理装置は、画像内の検査対象領域に含まれる画素の画素値を近似する複数の近似面を算出する近似面算出部16と、検査対象領域内の画素の画素値と上記複数の近似面との関係に基づいて、上記複数の近似面から少なくとも1つの近似面を選択する近似面選択部17と、上記少なくとも1つの近似面によって近似される近似領域を決定する近似領域決定部18と、近似領域内の画素の画素値と、該画素の座標に対応する少なくとも1つの近似面における近似面上の値とに基づいて異常部を検出する異常部検出部20とを備える。【選択図】図1
