摘要： A horizontal synchronizing signal is applied as a reference signal and a voltage-controlled oscillator outputs a display clock signal on the basis of the frequency of the horizontal synchronizing signal. The frequency of the display clock signal is frequency-divided in accordance with a frequency-dividing value selected from among a plurality of frequency-dividing signals stored in advance, the difference in frequency between the frequency-divided display clock signal and the horizontal synchronizing signal and the phase difference between them are obtained by a phase comparator, and the frequency of the signal outputted by the voltage-controlled oscillator is decided in dependence upon the frequency difference. In an interval in which a vertical synchronizing signal turns off and the frequency of the horizontal synchronizing signal fluctuates, the reference signal and the horizontal synchronizing signal input to the phase comparator are held fixed to prevent a fluctuation in the outputted display clock.
