The first and the second read buffer memories read out a sequence of data segments of previous gray data from the frame memory and alternately output the previous data segments to the gray signal converter. The frame memory stores a plurality of previous and current data segments, and the total amount of the data segments stored in the frame memory is equal to or larger than those for one frame.
