摘要： A color image of a circuit board is divided into respective color regions. Plural representative colors are set, and angle indices and distance indices are calculated for each pixel color in the color image in a predetermined color space. The angle indices for a particular pixel color represent angles between an individual color vector representing the particular pixel color and plural representative color vectors of the plural representative colors. The distance indices for a particular pixel color represent distances between the particular pixel color and the plural representative colors. Composite distance indices are then calculated for each pixel color in the color image, based on the distance indices and the angle indices. Each pixel in the color image is classified into plural representative color regions associated with the plural representative colors according to the composite distance indices, thereby dividing the image region of the color image into the plural representative color regions.

摘要： 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.

摘要： A pattern-element extractor (51), one of functions implemented by a computer, extracts a plurality of pattern elements from a reference image, a region of which is displayed on a display (45). An input part (46) accepts an operator's selection of one out of the plurality of pattern elements as a reference pattern element, and a distinguishability checker (52) checks whether the selected pattern element is distinguishable from the other pattern elements and usable as the reference pattern element for pattern matching. A result of the check is notified to the operator, and an appropriate one out of the pattern elements in the reference image can be selected as the reference pattern element, by referring to the result of the check made by the distinguishability checker (52). Thus, misrecognition of the reference pattern element used for detecting a position of a target image relative to the reference image in pattern matching is prevented.

摘要： A board (9) is placed on a stage part (20) so that the back surface of the board is opposed to the stage part (20). The stage part cuts off light entering a hole penetrating the board (9) from a side of its back surface which is a reverse surface with respect to its pattern formed surface and has a reflection property which is different from that of the pattern formed surface with respect to an illumination light, and the illumination light is emitted from a light source part (31) onto the pattern formed surface (9a). An image pickup part (33) receives light from the pattern formed surface to acquire an inspection image, and a hole-area specifying part implemented by a computer (4) specifies a hole area in the inspection image, which corresponds to a hole of the board (9), by using only the inspection image as image information, in accordance with criteria of pixel values affected by a reflection state of the illumination light entering a hole penetrating the board (9) and being reflected on the stage part (20). Thus, it is possible to detect an area of a hole on the board (9) by using only the inspection image acquired with a reflected light of the illumination light from the light source part (31).

摘要： 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.
