对比机就是对的 选定Source

External 选定Picturemode和客户确认好需要按照对比机的哪个picturemode来调，大多数客户使用对比机VividmodeYPbPr下一定要记得做AutoColor.选用100%ColorBar来做，比如仪器802BT上的ColorBar。做之前先打开VGASource几乎不会调整，如果VGAsource有颜色一场。可以做AutoColor来排除看看会不会好。VGASource选用有黑白的pattern来作AutoColor。 External仪器准备和热NCSTool:W/RPC/对比机/色温仪/分配器/download线/ color/Gamma用)/DVD/YPbPr线 ,GammaAdaptiveLuma、SCE ExternalOutlineGammaAdaptiveSCE(SecondaryColorNR(Noise ExternalExternalExternal和色Copyright©MediaTekInc.All ExternalAgendaPanelGamutAuto调色温(Color ExternalPanelmut21/Whyneed yzepanelPQfinetuneisalargetime-consumingprocess.Byyzingpanelcharacteristic,itcanbeknowninadvancewhetherthepanelcanapproachtobenarkbytuning.Differentdecisionwillbetakentofinetuneaccordingtopanel’s ExternalPanelGamut量测NamingIC_panel:MTKfinetunetarget arkMeasurepanelMeasureIC_panelandRef_panel100%R/G/B(x,y),white/black(x,y)andLvvaluesbyCA210.Calculatecontrast=Lvwhite/IfIC_contrastRef_contrast我们所调的panel对比度不如对比机，对比度就很难ifIC_GamutareaRef_Gamutarea所调Panel色域比对比机小ediaTekInc.AllediaTekInc.All Gamma调整前准备工
