摘要: A position detection method of detecting a position of a detection mark. The method includes a matching step of calculating a value of a correlation using a template for an image including the detection mark, a change step of changing the template to be used for the correlation, a repeat step of, when a value of a correlation in the matching step is not more than a predetermined value, changing the matching processing while changing the template in the change step, and a step of performing position detection on the basis of a result of correlation in the matching step or the repeat step.

摘要: A method of detecting a position of a mark within image data. The method includes a first step of obtaining a first position of the mark based on a first degree of correlation between a first template and the image data, the first template having a first feature point to obtain the first degree of correlation, a second step of obtaining a second position of the mark based on a second degree of correlation between a second template and the image data, the second template having a second feature point, of which a position is different from that of the first feature point, to obtain the second degree of correlation, and a third step of detecting the position of the mark through the first and second steps.
