摘要： According to one embodiment, a defect classification apparatus includes a processor. The processor acquires a first design image which is an image based on design data created by design software and relates to a first inspection target, and acquires a first real image which is captured by imaging the first inspection target produced based on the design data. The processor converts the first design image to a reference image represented by using a second real image captured by imaging a second inspection target without a defect. The processor calculates a reliability of the reference image. The processor detects a defect in the first inspection target by comparing the reference image and the first real image and classifies the defect, based on the reliability.

摘要： According to some embodiments, an image processor includes an image acquirer, a first image generator, a point acquirer, a detector, a calculator and a determiner. The detector detects a second plurality of points in the first perspective images or the second perspective images corresponding to the first plurality of points. The calculator calculates, based on at least the first plurality of points and the second plurality of points, a difference in position of the target between when the first perspective images were captured and when the second perspective images were generated. The determiner determines whether or not the difference is in a range. If the difference is not in the range, then the first image generator generates updated ones of the second perspective images from an updated one of the volume data, which is different by the difference from a previous one of the volume data.
