摘要： An operation part in a pattern inspection apparatus includes a defect candidate image generator for generating a binary defect candidate image representing a defect candidate area in an inspection image by comparing the inspection image with a reference image, in an inspection image masking part the inspection image is masked with the defect candidate image to obtain a masked inspection image. In a feature value calculation part, an autocorrelation feature value is obtained from the masked inspection image, and outputted to a classifying part. The classifying part comprises a classifier outputting a classification result on the basis of the autocorrelation feature value and a classifier construction part for constructing the classifier by learning. It is thereby possible to easily perform the high accurate classification of defect candidate using the autocorrelation feature value which is hard to characterize as compared with geometric feature value or feature value representing density.

摘要： In a defect detection apparatus 1, in a reference image inspection circuit 42 compared are a reference image representing a pattern in a die which is determined as a reference on a substrate 9 and a plurality of supervisory images which represent patterns in selected block areas, respectively, to detect defects included in the reference image. Subsequently, in the target image inspection circuit 44, a target image representing a pattern in another die and the reference image are compared to detect a plurality of defect candidates included in the target image. Then, a defect detector 45 excludes defect candidates overlapping with the defects included in the reference image from the plurality of defect candidates on the basis of at least positional information of the defects included in the reference image. This makes it possible to detect defects existing in the pattern in another die accurately while eliminating effects of the defects existing in the pattern in the die which is determined as the reference.

摘要： As light is allowed to impinge from above a microplate M and an imaging unit 13 (a line sensor 131 and an imaging optical system 132), which moves in a scanning motion along the bottom surface of the microplate M, receives transmitted light, images of wells W formed in the microplate M are captured. The scope of imaging by the line sensor 131 is greater than the diameter of at least one well W, or preferably, encompasses a plurality of wells. When the depth of field of the optical system 132 is 0.6 mm or less, the influence of reflection of side walls of the wells upon the images is reduced.

摘要： Light is allowed to be incident from above wells provided on a microplate M and the light transmitted to the lower surface is received to obtain an original image of the wells (Step S101). Detection target areas in the original image are specified by an appropriate image processing (Step S102), and peripheral areas as backgrounds surrounding the respective detection target areas are specified (Step S103). By calculating a density value of the detection target area Ri using luminance information of the detection target area Ri and that of the peripheral area Si surrounding this detection target area Ri for each detection target area Ri (Steps S105, S106), the influence of a well wall surface reflected on the background is eliminated.

摘要： In a technique for displaying images of recess portions formed on a sample holding plate, an image display apparatus or an image display method is provided which has a displaying function which makes it possible for a user to compare and observe the images from various perspectives. From a total image obtained by shooting a micro plate as a whole, areas corresponding to wells are cut out. Image processing, such as color coding and contour enhancement, is performed on images of the wells based on classification results obtained using a classification criterion designated by the user, thereby forming material images. The material images are arranged in such an arrangement in accordance with the sequence on the micro plate, thereby forming an image for displaying. Classification results obtained using different classification criteria are displayed side by side, which makes it easy to compare and observe from different perspectives.
