Advanced Color Adjustments
Gamma adjustment
Differences between equipment may result in a
slight variation in the coloring when images are
projected, and you may want to adjust this.
(Projection will stop temporarily during such
adjustment.) There are two methods of doing so. One
is to select one of the gamma correction values [2.0],
[2.1], [2.2], [2.3], [2.4]. The other is customized
adjustment, which is done with reference to the
projected image or a gamma graph. The gamma
graph's horizontal axis represents the input signal
level and its vertical axis the output signal level.
Adjustment is not possible when "Color Mode" is set
to "x.v. Color".

When a smaller value is selected, the dark areas
of images become brighter, but the lighter areas
may become oversaturated. This is indicated by
bulging in the upper portion in the gamma graph.
When a larger value is selected, the bright areas
of images become darker. This is indicated by
bulging in the lower portion in the gamma graph.
