7.4. Black level uplift: [Offset] & [Corner] adjustment
➢
If the ambient light is dark, audience will see grey region in Edge Blending area. It is due to light
leakage from projector optical system
and can’t be fixed by signal processing. Low contrast ratio
projector will be more serious. The only solution is to apply [Offset] function to uplift the color in
non-transition area to compensate the visual color difference.
➢
Projector with higher native (not dynamic) contrast ratio will have less light leakage. Usually, DLP
projector will have higher contrast ratio with better result. DLP Laser projector has high native
contrast ratio with accurate color and gamma setting and is suitable for edge blending.
➢
[Corner] function is to do accurate position alignment.
7.4.1. [Offset]
➢
[Offset] is to set the level for color uplift. It should be determined based on the brightness level in
overlap region.
