Abstract:
1. In a processing device associated with a display device that has a plurality of pixels, each pixel having red, green and blue sub-pixels components each of which is of separately controllable, and wherein the red, green and blue sub-pixel component are arranged to form either vertical or horizontal stripes, a method of using both horizontal and vertical dropout control adapted to compensate for thin image features when rendering the image, comprising: an act of receiving a bitmap having a plurality of samples representing an image; for the direction that is perpendicular to the striping formed by the sub-pixel components, for the direction that is parallel to the striping formed by the sub-pixel components, a step for determining whether the samples of the second set of samples are positioned with respect to boundaries of a pixel such that a weighted anti-aliasing filtering will take sufficient account of the second set of samples.
