色度信号的相角与色调之间的关系

The relation between phase angle of chrominance signal and hue

分析并计算了色度信号的相角与色调之间的关系．结果表明，当ν＝１时，恒定色调对应恒定相角；ν≠１时，经ν校正后，上述对应关系只适用于三基色和三补色，而对于三基色和三补色以外的其它彩色，这种对应关系只在饱和度较低时近似成立，饱和度较高时则出现较大偏离，且随着色调的不同。

The relation between phase angle of chrominance signal and hue is analysed and calculated.The result showed that when ν =1,constant hue corresponds to constant phase angle; ν ≠1,above mentioned correlation of all ν corrected colors is approximatively right only in lower saturation values except primary and complementary colors.
