  • Publication number: 20060018534
    Abstract: The present invention provides a technique to prevent increase in defect detection processing volume due to the shape of an object subject to the defect detection. An image of an object under inspection with a plurality of color regions is divided into areas by area segmentation according to colors. From the result of the segmentation, an inspection image representing a shape of a specific region among the plurality of color regions is obtained. The inspection image and a comparison image which is comparable at least in part with the inspection image are then compared to detect defects relating to the specific region.

  • Publication number: 20060008140
    Abstract: The present invention provides a technique to improve reliability of a segmentation result for a subject image, which is obtained a colored object with the possibility of change in color for each individual items. In a specified color space, existing color areas indicating ranges of colors containable in the subject image when the colored object has an allowable range of color, and non-existent color areas for outside the existing color areas are set. Then, subject image segmentation is performed by classifying colors of pixels of the subject image into the existing color areas and the non-existent color area.

  • Publication number: 20050254699
    Abstract: In a reference binary image representing a pattern including wires formed on a substrate, an erosion is performed on a specific area having the same pixel value as a pixel value corresponding to a wire area to acquire an eroded image and a dilation is performed on the specific area which remains in the eroded image to almost the same degree as the erosion to acquire an eroded and dilated image. Subsequently, a differential image between the eroded and dilated image and the reference binary image is generated as a wire image representing a wire area. It is thereby possible to easily extract a wire area which is a fine pattern area. By setting respective different defect detection sensitivities for the wire area and the other area on the basis of the wire image and detecting a defect in an inspection image in accordance with the defect detection sensitivities, it is possible to appropriately detect a defect in a pattern on a substrate.
