IMAGE PROCESSING METHOD FOR REMOVING ALIASING AND IMAGE PROCESSING DEVICE APPLYING SAME

摘要

Provided are an image processing method for removing aliasing and an image processing device applying the same. The image processing method receives data information about a polygonal image; determines the position of an interpolation vertex at an external angle of a vertex composing the polygonal image by using the data information about the polygonal image; interpolates an inputted polygon and a space of the polygon composed by the interpolation vertex according to interpolation coefficients; and outputs the interpolated polygonal image. As a result, aliasing can be removed even when the complex polygon is displayed or the size of the image is changed. Also, the amount of computation is reduced by interpolating only primitives to overcome the aliasing rather than the whole inputted image.;COPYRIGHT KIPO 2014;[Reference numerals] (AA) Start;(BB) End;(S1010) Input data information about a polygonal image;(S1020) Determine the position of an interpolation vertex by using the data information;(S1030) Interpolate a space of the polygon composed by an inputted polygon and the interpolation vertex according to interpolation coefficients;(S1040) Output the interpolated polygonal image
