PROBLEM TO BE SOLVED: To facilitate the adjustment work to suppress the rise of the production cost. SOLUTION: A signal processed in a digital integrated circuit 30 for video signal processing is taken out to an output pin 302, and a signal from a prescribed signal generation circuit 350 incorporated in this integrated circuit 300 is taken out to the output pin 302 also. A signal from this output pin 302 is supplied to an input pin 6 of an analog integrated circuit 200 for video signal input/output, and a signal from this input pin 6 is supplied to a band stop filter 8, which stops the band of a chroma signal, through a low pass filter 7. Further, a luminance signal which has this chroma signal stopped is taken out from an output pin 9 to an output terminal 400. At the time of adjustment, for example, 100% chroma signal is formed in a signal generation circuit 350, and this signal is supplied from the output pin 302 to the input pin 6 of the integrated circuit 200, and the signal taken out to the output terminal 400 is supplied to a waveform monitor device 600. |
