<p>PURPOSE:To smoothly display a stepwise part and to reduce the loss of orthogonality by recording smooth line data generated by line data generating means on a line between recording of Ni line data and recording with Ni+1 line data. CONSTITUTION:When a 2-line recording system is selected in a ROM 2, a program for converting line data to be recorded on a second line is stored. A RAM 25 has a line data area for storing Ni line data and Ni+1 line data supplied to a microcomputer 26, a X data area for storing exclusive OR X thereof, a Y data are for storing logic product Y, a n count area for counting bit length (n) continued with logic '1' in the exclusive OR X, a count area for counting the bit length of Ni line data, a S data area for storing smooth line data S, and areas for storing the bit state of the exclusive OR X, logic product Y, intermediately processed data X', etc.</p> |
