Generating circuit of color bar signal
专利汇可以提供Generating circuit of color bar signal专利检索，专利查询，专利分析的服务。并且PURPOSE: To enable color balance adjustment easily, by incorporating the circuit performing anti-correction for the pick up performance made at the encoder, performing anti-correction only at the selection to the color bar signal, and obtaining normal color bar output.
CONSTITUTION: The video input signals of R,G,B are inputted to the terminals 1,3,5 and the color bar signals of R,G,B are inputted to the terminals 2,4,6 respectively. For example, the R color bar signal mixed with the B color bar signal by the variable resistor VR is the signal of B+mR(where; m is the masking correction amount) and is fed to the B-Y color difference amplifying circuit 9 via the resistor R
7 . The value of m is adjusted with the resistor VR to obtain the color difference signal of B-Y. Thus, the color balance adjustment can easily be made, by incorporating the circuit performing anti-correction for the pick up performance made at the encoder and obtaining the normal color bar signal not performing anti-correction only when selected to the color bar signal.
