PROBLEM TO BE SOLVED: To provide a method for correcting ununiformity in an image picked up from an object to be examined by an imaging apparatus and to improve correction of ununiformity in the image.SOLUTION: In the method for correcting the ununiformity in the image photographed from the object to be examined by the imaging apparatus, an image to be corrected is picked up, a correction image is computed from the image to be corrected, the picked up image is corrected using the correction image in order to create an image which is normalized by multiplication of the image to be corrected and the correction image, when the correction image is computed, a pixel having lower signal strength than the limiting value in the neighborhood of the picked up object to be examined is identified, and signal strength, which is respectively dependent on the signal strength of each neighboring pixel, is assigned to these pixels.COPYRIGHT: (C)2006,JPO&NCIPI【課題】画像内の不均一性の補正を改善する。【解決手段】画像化装置によって検査対象から撮影された画像内の不均一性の補正方法において、補正すべき画像を撮影し、補正すべき画像から補正画像を算出し、補正すべき画像と補正画像との乗算によって正規化された画像を作成するために、撮影された画像を補正画像を用いて補正し、補正画像を算出する際に、撮像された検査対象の付近において限界値よりも低い信号強さを有する画素を識別し、これらの画素に、それぞれの近隣の画素の信号強さにそれぞれ依存する信号強さを割り当てる。【選択図】図4
