Abstract:
PURPOSE: An image generating method, a substrate inspecting method, and a recording media and a substrate inspecting device for performing the image generating method and the substrate inspecting method are provided to reduce the number of intention failure wrongly detected and to detect actual failure. CONSTITUTION: An image generating method having a filter image generating process is as follows. A pixel value of a pixel positioned on the circumference of a circle having a central position of recorded images as a center is converted into a maximum value among the pixel values of a plurality of pixels selected from the pixels positioned on the circumference so that filter images are generated(S14). Position coordinates of the pixel of the recorded images are converted into polar coordinates so that converted images are generated. Maximum data indicating a relation of the maximum value among the pixel values and the diameter of the circle is generated based on the converted images.
