PURPOSE:To reproduce an original image with fidelity, by identifying whether each dot in a dot information frame has the same color as the dot adjacent to each other, and applying the two multilevel hard copy on the dot so as to from a contour for the color set of a display picture plane when the dot has a different color. CONSTITUTION:Assuming that the dot to be decided is B0, the dots B1 and B3 out dots B1-B4 at upper and lower, and right and left sides, are colors (white) different from the dot B0, therefore, '1' is written on the dot B0. and similarly, since the dot C2 out of the dots C1-C4 at the upper and lower, and the right and left sides, is the color (yellow) different from the dot C0, '1' is written on the dot C0. By applying such processing, a binary value is written at a copying buffer memory 12. Accordingly, by performing the two multilevel copying by a printer 13, it is possible to obtain the two multilevel hard copy on which the contour of the color set (yellow) of a geometric graphic is formed. |
