Abstract:
1. A defect inspection system comprising: an image acquiring section for acquiring a two-dimensional image of an entire surface of each of a plurality of subjects; an image storing section for storing, as image data, the two-dimensional image of the entire surface of said each subject acquired by said image acquiring section; a defect extracting section for extracting defect data of the surface of said each subject based on a defect extraction algorithm using a predetermined parameter for the two-dimensional image read out from said image storing section, so as to extract a defect if the defect is determined to be present based on the defect extraction algorithm; a displaying section for displaying an image of each defect extracted by said defect extracting section, by superimposing the image of the defect on the two-dimensional image of a subject which is determined to have the defect; a parameter adjusting section for adjusting the parameter to set a new parameter to change a defect extraction degree for said each subject; and a quality judging section for judging whether said each subject is acceptable, by checking the defect data extracted by said defect extracting section with reference to defect data registered in advance in a defect dictionary, wherein when the parameter is adjusted by the parameter adjusting section:
