Abstract
PURPOSE:To obtain a velocity modulation (VM) signal with high accuracy subject to time adjustment without deteriorating the performance of a signal line by using the output of a 1st D/A converter as a velocity modulation signal and using the output of a 2nd D/A converter as a video signal. CONSTITUTION:Delay circuits 15, 16 retarding a 1st digital signal by a prescribed time, the 1st D/A converters 3, 4 converting the 1st digital signal into an analog signal, and a 2nd D/A converter 17 converting the output signal of the delay circuits 15, 16 into the analog signal are provided and the output of the 1st D/A converters 3, 4 is used as a velocity modulation signal and the output of the 2nd D/A converter 17 is used as a video signal. That is, the delay circuits 15, 16 retard the signal in the digital signal processing circuit, the signal corrected by the time retarded in the VM circuit is extracted as the VM signal with respect to the luminance signal and converted into the analog signal by the D/A converters 3, 4, 17. Thus, the signal with high accuracy is obtained.
