在电视系统、设备及彩色电视接收机的测试中,色度-亮度的不均匀性是一项主要的测试项目。精确的测量需要一台专用测试仪器,在没有专用测试仪器的情况下,只能从波形监视器或示波器上读得一些间接的数据,然后通过一定的计算才能获得色度-亮度增益、时延差的具体数值。本文介绍一种 Chrominance-luminance non-uniformity is a major test item in the testing of television systems, equipment and color television receivers. Accurate measurement requires a dedicated test instrument, in the absence of a dedicated test instrument case, only from the waveform monitor or oscilloscope to read some of the indirect data, and then through some calculations to get the color - brightness gain, delay The specific value of the difference.
