Abstract:
A method for displaying grey-scale images at a desired grey scale resolution on a display having a matrix of pixels, comprising the steps of:defining one or more control matrices, said control matrices having a size equal to the desired grey scale resolution of the display, each position in said control matrices having an assigned value in a range with a size equal to the desired grey scale resolution;horizontally and vertically mapping said control matrices into said display a number of times, such that each pixel in the matrix of pixels in the display corresponds to a location in one of the control matrices mapped into said display;comparing the control matrix value of each pixel in a frame of an image to be displayed on said display to an ON range and turning that pixel on if the control matrix value of that pixel is within said ON range, the extent of said ON range being equal to the grey scale value of that pixel and contained in a circular queue having a size equal to said desired grey scale resolution; andchanging the ON range in said circular queue for each successive frame by an amount equal to the grey scale value of that pixel.
