Abstract
Data about display start positions are stored in an H register. An H start counter counts an original oscillation signal ORGCLK after the termination of a flyback period, and a comparator detects a start position. Flip flops and NOR gates form a clock having a cycle one and a half times as long as that of the original oscillation signal from the start position, and either the signal having a 1.5-fold cycle or the original oscillation signal is selected according to the level of a mode signal MODE. Thus, it is possible to obtain a clock OSDCLK having a frequency the same as that of the original oscillation signal up to the start position and a clock OSDCLK having a frequency corresponding to magnification from a display position. Therefore, by controlling display of characters based on the clock OSDCLK, display start positions can be made even regardless of magnification.
