Abstract

In order to solve the problem that information indicating three or more points on a contour of a figure drawn by an electron beam writer cannot be more precisely acquired, an information processing apparatus includes: an accepting unit that accepts pattern information indicating a pattern figure, and actually observed contour information acquired using an image obtained by capturing an image of a figure drawn by an electron beam writer; a transforming information acquiring unit that acquires transforming information, which is information that minimizes the sum of squares of differences between convolution values corresponding to three or more corrected contour points of a given point spread function in a region indicated by the pattern figure indicated by the pattern information and a threshold regarding the convolution values; a corrected contour point acquiring unit that acquires corrected contour point information, which is information indicating three or more corrected contour points respectively corresponding to three or more actually observed contour points, using the transforming information; and an output unit that outputs the corrected contour point information. Accordingly, it is possible to more precisely acquire information indicating three or more points on a contour of a figure drawn by an electron beam writer.
