Advanced... (Continued) • Color Management In most installation situations, color management is not 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. Proper color management can be achieved under controlled and reproducible viewing conditions. 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 give guidances or send an experienced professional installer for you. The Color Management function provides six sets (RGBCMY) of colors to be adjusted. You can select any of them to adjust its color range and saturation. 1. Press OK to display the Color Management window. 2. Select Primary Color and use / to select a color from Red, Green, Blue, Cyan, Magenta, and Yellow. 3. Press to select Hue and use / to set its range. Increase in the range will include colors consisted of more proportions of its two adjacent colors. Red Yellow Green Magenta Cyan Blue The illustration shows 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 select Saturation* and use / to adjust its values. Every adjustment made reflects to the image immediately. For example, if you select Red and set its value at 0, only the saturation of pure red will be affected. 5. Press to select Gain and use / to adjust its values. The contrast level of the primary color you just selected are affected. Every adjustment made reflects to the image immediately. 6. Repeat steps 2 to 5 until you have made all of the desired adjustments. 7. When done, press BACK to save your changes and exit. *About saturation It 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. The function is accessible through the remote control. • Noise Reduction Reduces electrical image noise caused by different media players. The higher the value, the less the noise. 34 Menu Functions
