Some examples:
The first column shows the aspect ratios for a standard television signal with 4:3 image information. The only correct aspect ratio is
4:3. In all other cases the image is transformed.
The second column shows the aspect ratios for a standard television signal with 16:9 image information. The only correct aspect

What can be done ?
The color temperature can be selected according to the type of source:
There are 5 different preset color temperatures:

• Projector white
• computer : 9300 K
• Video : 6500 K
• Film : 5400 K
• Broadcast : 3200 K
These calibrated presets can be selected and will provide optimum color tracking, the projector allows however the setting of a
personal color temperature, this is done incustom
Projector white will provide maximum projector light output.

8.6 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.
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). Acustom 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.
How to switch the color space ?
1. PressMENUto activate the menu bar.
2. Press→to select theImageitem. (image 8-24)
3. Press↓to pull down theImagemenu.
4. Use↑or↓to selectColor space.

8.7 Filmmode detection
What can be done ?
Some sources like common DVD material are derived from cinema 24 Hz sources (2/2 or 3/2 pull down method).
The filmmode detection insures that these converted signals are shown without artefacts.
This function may cause undesired effects on standard sources, therefore it can be disabled (OFF) at any time
2:2 pull-down
The process of transferring 24-frames/sec film format into video by repeating each frame (used for PAL DVD’s) as two
video fields. ( AD )
3:2 pull-down
Method used to map the 24 fps of film onto the 30 fps (60 fields) or 25 fps (50 fields), so that one film frame occupies
three video fields, the next two, etc. It means the two fields of every other video frame come from different film frames
making operations such as rotoscoping impossible, and requiring care in editing. Some sophisticated equipment can
unravel the 3:2 sequence to allow frame-by-frame treatment and subsequently re-compose 3:2. The 3:2 sequence
repeats every fivevideo frames and four film frames, the latter identified as A-D. Only film frame A is fully on a video
frame and so exists at one time code only, making it the editable point of the video sequence.
Artefacts
Undesirable elements or defects in a video picture. These may occur naturally in the video process and must be
eliminated in order to achieve a high-quality picture. Most common in analog are cross color and cross luminance.
Most common in digital are macroblocks, which resemble pixelation of the video image.
Enabling/disabling the filmmode detection
1. PressMENUto activate the menu bar.
2. Press→to select theImageitem. (image 8-27)
3. Press↓to pull down theImagemenu.
4. Use↑or↓to selectFilmmode detection.
5. Press→to pull down the menu.
6. Use↓or↑to enable or disable the Filmmode detection.
7. PressENTER.
A white bullet shows the active setting.

8.8 Input Balance
Overview
• Introduction to Input Balance
• Adjusting the input balance
• Input balance for YPrPb signals
8.8.1 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 8-28 , 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 “black not 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 8-29
