Abstract
Aliasing on a video display resulting from digital sampling and appearing as jagged lines and crawling movement is eliminated by controlling the intensity of video display pixels as a function of distance from the ideal line location. Intensity values are stored in an intensity lookup table as a function of two values. For the middle portion of a line, the two values are the shorter of the distance from a pixel in either the x-direction or y-direction and the smaller of the slope with respect to the x-axis or the y-axis. For line end points, the two values are the distances of the pixel from the end point in the x-direction and the y-direction.
