Abstract
PURPOSE: To realize a picture processing system available for the high-density processing and reproduction of a multilevel picture by determining the density of a small picture element, forming one sampling picture element, by the algebraic mean of density between picture elements adjoining to the sampling picture element.
CONSTITUTION: To judge picture element S surrounded with picture elements A, B, C, and D in contact with four straight lines, the input picture S is outputted by dividing into four small picture elements α=(A+B)/2, β=(B+C)/2, γ=(C+ D)/2 and δ=(D+A)/2. For the purpose, input buffer register 21, after being stored with input data signals obtained in time sequence according to the scan on the picture, sends pieces of data A, B, C and D out and adder group 22 and multiplier group 23 compute (A+B)/2, (B+C)/2, (C+D)/2, and (D+A)/2. Then, multiplexers 24, 25 and 27 and shift register 26 send data G0 out in the order of (α), (δ), (β) and (γ).
