Black level setting : brightness White level setting : contrast The same absolute black and white level for the three colors allows the same reference for Brightness and Contrast control of the picture ! These two references also set the range in which the ADC will work for that particular source (this explains also why each input balance setting is linked to a particular source and thus saved in the image file). R59770021 CLM R10+ 11/10/2010 9.Imagemenu 9.3.9.2 Adjusting the input balance How can it be done ? To balance the three color signals of a particular source there are conditions; in fact we must know the black and the white level of the source i.e. : 1. The source in question must be able to generate a white signal, ideally a 100% white (background) full screen pattern 2. The source in question must be able to generate a black signal, ideally a 100% black (background) full screen pattern AB Image 9-44 White balance : In the projector, we will set the contrast for each color until we get a 100% light output picture when projecting a 100% white image (image A) Black balance : In the projector, we will set the brightness for each color until we get a 0% light output picture when projecting a 100% black image (image B). The changeover from min to max is indicated by the apparition of bright spots also called “digital noise” An alternative to a full screen White/black pattern is the standard gray scale pattern, the white bar will be used for white balance and the black bar for black balance. Image 9-45 Black balance 1. Press MENU to activate the menus. 2. Use the ^ or Ў key to select Image and press ENTER. 3. Use the ^ or Ў key to select Image settings and press ENTER. 4. Use the ^ or Ў key to select Input balance and press ENTER. 5. Do you want to use an internally generated test pattern ? If yes, Use the ^ or Ў key to select Test pattern and press ENTER to toggle between [on] and [off] If no, Adjust on the selected source. 6. Use the ^ or Ў key to select Black balance and press ENTER. Depending whether a test pattern is selected or not, the adjustment image is displayed. 7. Toggle with ^ or Ў key to select Black balance red. (image 9-46, image 9-47, image 9-48, image 9-49, image 9-50) 8. Adjust the red black level on a minimal value R59770021 CLM R10+ 11/10/2010 9.Imagemenu 9. Toggle with ^ or Ў key to Black balance blue and adjust the blue black level on a minimal value. Note: This minimal value is not necessary , provided that the 2 other colors are not influencing too much the color to be adjusted, in fact the aim is to minimize the effect of the two other colors since there is a risk of reaching too soon the 50% transition due to the contribution of these two other colors signals. 10.Toggle with ^ or Ў key to Black balance green and adjust the Green black level until bright spots appear on the screen. 11.Toggle with ^ or Ў key to Black balance blue adjust the Blue black level until bright spots appear on the screen. 12.Toggle with ^ or Ў key to Black balance red adjust the Red black level until bright spots appear on the screen. The projected image should now be noisy full black Image 9-46 Image 9-47 Image 9-48 Image 9-49 Image 9-50 If one uses a gray scale pattern, the bright spots should appear in the black bar. Performing White input balance 1. Connect the source you want to project. 2. Press MENU to activate the menus. 3. Use the ^ or Ў key to select Image and press ENTER. 4. Use the ^ or Ў key to select Image settings and press ENTER. 5. Use the ^ or Ў key to select Input balance and press ENTER. 6. Do you want to use an internally generated test pattern? If yes, Use the ^ or Ў key to select Test pattern and press ENTER to toggle between [on] and [off] If no, select a white pattern (or gray scale as alternative). 7. Use the ^ or Ў key to select White balance and press ENTER. The white balance bar scale for a typical color is displayed. 8. Toggle with the ^ or Ў key to select White balance red. (image 9-51, image 9-52, image 9-53, image 9-54, image 9-55) 9. Adjust the red white level (gain) on a minimal value 10.Toggle with ^ or Ў key to Whitebalanceblue and adjust the blue white level (gain) on a minimal value. Note: This minimal value is not necessary , provided that the 2 other colors are not influencing too much the color to be adjusted, in fact the aim is to minimize the effect of the two other colors since there is a risk of reaching too soon the transition (bright spots) due to the contribution of these two other colors signals. 11.Toggle with ^ or Ў key to White balance green and adjust the Green white level (gain) until bright spots appear on the screen. 12.Toggle with ^ or Ў key to White balance blue adjust the Blue white level (gain) until bright spots appear on the screen. 13.Toggle with ^ or Ў key to White balance red adjust the Red white level (gain) until bright spots appear on the screen. The projected image should now be noisy neutral gray. R59770021 CLM R10+ 11/10/2010 9.Imag...
