Abstract
A pattern correction amount calculating apparatus includes: an accepting unit that accepts pattern information; a micro side group acquiring unit that acquires a micro side group, which is a group of continuous sides forming a contour of a pattern figure indicated by the pattern information, and is a group of micro sides that are each small enough to satisfy a predetermined condition; a virtual side acquiring unit that acquires a virtual side, which is a side that approximates micro sides contained in the micro side group; a virtual side correction amount calculating unit that calculates a virtual side correction amount, which is a correction amount for the virtual side; and a micro side correction amount calculating unit that calculates micro side correction amounts, which are correction amounts respectively for the micro sides contained in the micro side group corresponding to the virtual side, using the virtual side correction amount.
