6.4.2 Color Space
Color space
A color space is a mathematical representation for a color. For example, the RGB color space is based on a Cartesian
coordinate system.
This function is only available when the P7 functionality is activated. P7 functionality is a option for the XLM
projector and must be factory activated.
What can be adjusted ?
The color space (gamut), the collection of colors which can be reproduced by the projector, can be adjusted to 3 predefined stored
values (one projector specific and 2 international standards). A custom adjustment is possible. The maximum color space which
can be displayed is the projector color space. This color space is measured at the factory and stored inside the projector.

Note that it is common practice to set the targets outside the projector color space. This implies there would
be clipping if a fully saturated input was applied. In normal scenes, this does not happen, and the extra gain
or saturation helps balance the overall lock. If clipping occurs, there will typically be a hue shift when one of
R, G, B goes into clip ahead of the others.
6.4.3 Color Temperature
It is possible that when P7 is activated and the color temperature has been changed, the screen is all black
(no picture, no OSD). This can happen, due to the fact that for every change in color space setting the color
temperature also has to be set (that has to be done on the LCD as the OSD has disappeared).
6.4.3.1 Color Temperature selection
What can be done ?
The color temperature can be selected according to the type of source.
There are 3 different preset color temperatures, 3200 K, 6500 K and 9300 K. These calibrated presets can be selected and will
provide optimum color tracking. The projector however allows the setting of a personal color temperature incustomor to choose for
Projector white.

About custom color temperature
The custom values depend on the activation of the P7 functionality.
When no P7 functionality is activated, the custom color temperature is adjusted by the RGB gain.
When the P7 functionality is activated, the custom color temperature is based on the White point adjustment (X and Y adjustment)

Gamma
The transfer characteristics of most cameras and displays are nonlinear. For a display, a small change in amplitude
when the signal level is small produces a change in the display brightness level, but the same change in amplitude at a
high level will not produce the same magnitude of brightness change. This nonlinearity is known as gamma. Different
gamma curves are available to compensate the nonlinearity.
Changing the gamma value
1. Push the cursor key↑or↓to highlightGamma. (menu 6-35)

6.4.6.1 Introduction to Input Balance
Introduction: Unbalanced color signals
When transporting signals, there is always a risk of deterioration of the information contained in the signals.
In case of information contained in the amplitude of the signals which is the case of data color signals (R, G, B),image 6-4 , we are
quite sure that the amplitude of these color signals is subject to alterations.
An example of alteration may be a DC component added to the signal, in the form of a DC offset repositioning the black level, since
thisblack level(“brightness”) will become crucial later on (clamping circuit) it will result in “blacknot being black”.
Another value that is subject to alteration is the amplitude of the signal, resulting in an altered “Gain” of the signal (“white level”or
contrast).
The alterations of the three color signals will happen independently i.e. the colors will end to be unbalanced, image 6-5

One can conclude here that a good color tracking can only be met by using three previously (input) balanced
color signals
Analog Digital Conversion
The analog color signals must pass through anAnalog/Digital conversion circuit prior to any digital processing in the PMP.
A typical ADC transforms the analog value into an 8 bit coded digital signal.
The graphic shows that when converting a signal containing a DC offset component the range of the converter is not optimally used.

One can conclude here that a good data conversion can only be met by using three previously (input) balanced

The objective of input balancing
The objective in input balancing is to “set” the same black level and the same white level for the three colors of a particular input
source.

R59770014 XLM HD30 25/05/2009 
						

							6. Adjustment Mode
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 imagefile).
6.4.6.2 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 6-7
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 foreach 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.
