Abstract
PURPOSE:To facilitate classification decision making by the kinds of detects by providing a 1st deciding means which decides the kind of a defect and a 2nd deciding means which decides the extent of a defect corresponding to the kind of the defect from the decision result of the 1st means. CONSTITUTION:A feature extracting circuit 2 extracts the features of the defect according to the scanning information of a detection part 1 and outputs them to a kind arithmetic circuit 23 and a classification arithmetic circuit 36. The kind arithmetic circuit 23 analyzes the extracted information to calculate the similarity with a parameter stored in a memory 13, and a kind determining circuit 33 determines the kind of the defect whose similarity becomes maximum. Then a selecting circuit 26 selects a parameter regarding the classification of the defect weighed corresponding to the kind of the defect in one of memories 16a, 16b...16n and a classification arithmetic circuit 36 analyzes the extracted information to calculate the similarity with the parameter selected by the selecting circuit 26; and a classification determining circuit 46 determines the classification of the defect whose similarity becomes maximum.
