Color Management
In most installation situations, color management will not be necessary, such as in classroom, meeting room, or
lounge room situations where lights remain on, or where building external windows allow daylight into the
room.
Only in permanent installations with controlled lighting levels such as boardrooms, lecture theaters, or home
theaters, should color management be considered. Color management provides fine color control adjustment to
allow for more accurate color reproduction, should you require it.
Proper color management can only be achieved under controlled and reproducible viewing conditions. You will
need to use a colorimeter (color light meter), and provide a set of suitable source images to measure color
reproduction. These tools are not provided with the projector, however, your projector supplier should be able to
provide you with suitable guidance, or even an experienced professional installer.
The Color Management provides six sets (RGBCMY) of colors to be adjusted to favorite colors. When you select
each color, you can independently adjust its color range and saturation according to your preference.
To adjust and store the settings:
1.
In the Picture -- Advanced menu, highlight Color Management and
press ENTER. The Color Management page displays.
2. Highlight Primary Color and press / to select a color from among
Red, Yellow, Green, Cyan, Blue, and Magenta.
3. Press to highlight Range and press / to select the color range you
wish to make adjustment. The bigger the range, the more proportions of
its two adjacent colors the color contains.
Please refer to the illustration to the right for how the colors relate to
each other. For example, if you select Red and set its range at 0, only pure
red is selected. Increasing its range will include both the red color close to
yellow and red color close to magenta.
4. Press to highlight Saturation and adjusts the color saturation level by
pressing /
.
If you select Red and set its range at 0, only the saturation of the pure red
will be affected.
Saturation is the amount of that color in a video picture. Lower
settings produce less saturated colors; a setting of “0” removes that
color from the image entirely. If the saturation is too high, that color
will be overpowering and unrealistic.
5. To leave and save the settings, press MENU once or EXIT twice.
