Abstract
PURPOSE: To obtain a picture of high qulity with diagonal information determined through comparisons between the density sums of picture-element rows and columns adjoining to a sampling picture elements, when outputting several density levels in the form of binary small picture elements quartered.
CONSTITUTION: To output picture element X in the form of quartered small picture elements O1 to O4, comparisons are made between component picture-element density sum S1=A+B+C of adjacent picture-element row (A, B and C) on the upper side of picture element X and sum S4=F+G+H of adjacent picture-element row (F, G and H) on the lower side of the picture element, and between the component picture-element density sums S2=A+D+F and S3=C+E+H of adjacent picture-element columns (A, D and F) and (C, E and H) on the left and right sides; for example, when the density of picture element X is 2/5 between 1/5 (white) and 5/5 (black) with S1<S4 and S2>S3, the density of each small picture element is determied like O3=1 and O1=O2=O4=0. In this way, the density of each small picture element is obtained through the comparisons between density sums of picture-element rows and columns on upper and lower side and on left and right side, so that diagonal information can be utilized.
