CRAZE MEASURING PROCESSOR

PURPOSE:To provide a craze measuring processor in which a capacity of a memory can be reduced and craze lines which are regarded, even if they are intermittent, as being integral can be grouped. CONSTITUTION:This craze measuring processor comprises a mask processing unit 3, a binary processor 4, and an area.center-of-gravity calculator 5, and generates craze mask information having craze coordinates and craze width from image data by using a mask zone. An entirety coordinates converter 8 converts entire coordinates, a thick craze data processing-area-along-mask processor 10 extracts and separates thick craze data and craze-along-mask data from thin mask data, and a craze line connection processor 11 and a craze vector data forming unit 13 connect craze mask information between opposed masks and generate craze vector data. With this structure, it may merely fetch the craze mask information having the craze coordinates and the craze width, and a capacity of a memory can be remarkably reduced.
