The resolution or image quality of a display or printer may be effectively increased without increasing the number of pels (picture elements, or dots by perturbing the positions of pels or dots so as to achieve smoother line edges. The total number of dots or pels in a field is not changed, but each dot or pel may be positioned at several (say, four) different (and generally overlapping) positions.
