R5906112 /09 UDX series1348.8.5 RGB adjustmentAbout RGB adjustmentThe purpose of black level correction is to ensure a uniform black level in multi projector setups. Even whentwo projectors are of the same type, different projectors will output slightly different colors for black due tominor variations in their optical components. So if the projected image of the projectors overlap, there will be 3different black levels: one for the zone where only the picture of the left projector (zone 1), one for the Blendzone (zone 2), and one for the zone where there is only the picture of the right projector (zone 3).Picture Left Picture RightBlend ZoneImage 8-63The black levels for zone 1 and zone 3 are typically corrected by defining a black level mask, which is appliedto the image of each projector. This system is already in place but the applied mask is monochrome.Using the Basic Black Level menu, you can already specify the area of the mask and its contents. But by usingthe RGB Adjustment page, you can specify the multiplication factors (gains) for the Red, Green and Bluecolors separately.How to perform an RGB adjustment1.
