摘要： Screen interpolation is done without using an expensive line buffer, etc., to enlarge and display an original image without incongruity. Rather than computing an interpolated pixel value as an average of adjacent pixel values and displaying the computed average pixel value in each frame, in accordance with this invention a pixel to be interpolated assumes one of the adjacent pixel values in each frame, but in successive frames assumes different adjacent pixel values in a mix such that the average value of the interpolated pixel over many frames becomes the desired interpolated value. Since successive frames are displayed very rapidly, to the human eye the afterglow (or visual persistence) phenomenon causes the screen to appear as if an enlarged image is being displayed at all times without incongruity (i.e., the varying values of the interpolated pixels are not noticed by the human eye).
