ABSTRACT:
A desired character mainly composed of standard width dots selected from a matrix of orthogonally disposed rows and columns is displayed on a screen during scanning of the screen in horizontal and vertical directions. The display is smoothed by a circuit responsive to data stored in a memory. The smoothing involves the selected addition or removal, to or from particular portions of the character, of a small dot having a width one-third of the standard dot width.
