Abstract
A method for displaying grey-scale images at a desired grey scale resolution up to the visible limit on a display having a matrix of pixels, includes the steps of: defining a plurality of control matrices, each of said control matrices having a size and equal to the desired grey scale resolution of the display, each position in each of said control matrices corresponding to a specific pixel of said display; defining a super matrix, each position in said super matrix corresponding to one of said plurality of control matrices and having an assigned number in a range equal to the desired grey scale resolution; turning on a selected number of pixels within each of said control matrices based upon the grey scale value of the pixel, the orientation of the pixels turned on based on the value of a circular queue of size equal to said desired gray scale resolution; and adjusting the starting value of said circular queue for each of said control matrices based upon the number contained in the position of the super matrix corresponding to each control matrix and the gray scale value of the incoming pixel.
