Summary:A frame correction method includes the following steps. Firstly, a correction frame is projected, wherein the correction frame has a number of original-boundary contour points. Then, in the first boundary contour adjustment, in response to a position adjustment of the first contour-adjusted one of the original-boundary contour points, correspondingly adjust the position of at least one symmetrical one of the original-boundary contour points, wherein at least one symmetrical one and the first contour-adjusted one are symmetrically disposed. Then, in response to the position adjustment of the first contour-adjusted one, a number of first new boundary contour points and a number of first open correction points are added.
