IMAGE DATA PROCESSING APPARATUS AND METHOD FOR DEFECT INSPECTION DEFECT INSPECTING APPARATUS AND METHOD USING THE IMAGE DATA PROCESSING APPARATUS AND METHOD BOARD-LIKE BODY MANUFACTURING METHOD USING THE DEFECT INSPECTING APPARATUS AND METHOD AND RECORDING MEDIUM

摘要

From shot image of the plate-like body, using the signal threshold value and extracts the defect candidate. From among the plurality of defect candidates extracted by the position of the width direction search identical defect candidate, and repeating the obtaining the position in the carrying direction of the defect candidate and the navigation distance between the conveying direction of the position of the adjacent defect candidate that, for the interval the frequency distribution is obtained. When the frequency of occurrence of the noted interval exceeds a frequency threshold, the plate-shaped body is determined as having a periodic defect in the transport direction. At this time, the frequency threshold is set to increase in the schematic shortened the interval of interest. ;
