Abstract
PURPOSE:To prevent important information from being omitted by determining scanning line information after conversion based on the logical state of the scanning line information before the conversion and the logical state of the scanning line information after the immediately preceding conversion which was already converted. CONSTITUTION:Image data stored in a memory 1 is converted by a CPU 4 according to a control program stored in a ROM 2 and output data 5 is formed. At that time, when both dots at the same position of the 2n-th and (2n+1)-th lines are ON (OFF), the dot at the same position of the N-th line after the conversion is made to be ON (OFF) unconditionally. On the other hand, when two pieces of dot information at the same position of the 2n-th line and the (2n+1)-th line are ON and OFF (OFF and ON) respectively, if the dot at the same position of the (N-1)-th line after the immediately preceding conversion is OFF, the dot at the same position of the N-th line is made to be ON (ON), and if the dot of the (N-1)-th line is ON, the dot at the same position of the N-th line is made to be OFF (OFF).
