PURPOSE:To provide a video signal processing circuit which converts a digital color difference signal into a chrominance signal as it is and is stably operated and is suitable for high integration. CONSTITUTION:A scanning line conversion part 4 outputs digital brightness signal and color difference signal. A A/D converter 14 converts the digital brightness signal into an analog brightness signal. The color difference signal sampled by a clock CK3 is converted into sampling rates of integer-fold fsc by DFFs 6, 8, and 9. The digital color difference signal is converted into a digital chrominance signal by a selector 10 and an EXOR circuit 12. A D/A converter 13 converts the digital chrominance signal into an analog chrominance signal. |
