PURPOSE:To improve a picture with regard to image data in real time without a printer capable of halftone output. CONSTITUTION:A high quality picture making circuit composed of F/F 21 to 27, OR circuits 28 to 31 and AND circuits 32 to 34 generates picture data whose line number is (twice, in this example) larger than original one and whose data number of one line is double from picture data in a line memory through the use of data on one notice picture element E and picture elements A, B, C and D in the neighborhood of it by RR, RL and II and outputs it to the printer. Thus, the resolution of a picture printed by the printer can be improved to four times. Besides, this processor can be switched so as to output picture data BO of only the notice picture element E. |
