METHOD AND DEVICE FOR DISPLAYING HALFFTONE IMAGE

摘要

A method and an arrangement for depicting half-tone images of equal-sized image dots provides an arrangement of the image dots in a grid having three directions of orientation at an angle of 60 DEG . Each image dot is thus equidistant from the six directly adjacent image dots. A constant number of adjacent grid positions is always used to form an image patch. The number of image dots in an image patch determines the grey step in question. The filling of the image patches with image dots according to the grey step to be produced always takes place following the same rule. The image dots associated with a particular grey step are equidistant from corresponding image dots in the six directly adjacent image patches.
