12.2 Introduction to image files
Introduction
An image file contains the main characteristics of a source (number of active lines,...). The projector’s memory contains a list of files
corresponding to the most common sources, these are the standard files (file extension= *.s). When a new source corresponds to
one of these files, a custom file (file extension=*.C) is created and saved for future use.
The maximum number of custom files that can be created is 99, the four last files are systematically overwritten.
When there is a little difference, the file can also be loaded and then edited until the source specs are reached.
The AutoImage function creates automatically the best suited image file (custom file) for a new source. Au-
toImage is used when:
- a new source is detected : AutoImage creates a new custom file which can always be edited if necessary.
- the AutoImage button on the RCU is pressed
AutoImage works only in full screen mode
If the AutoImage function does not succeed in finding a file and no file is loaded (load list is empty), which
means that the source is not displayed, then use thecopyfunction,

If the displayed image is not correct after AutoImage or after selecting the best fitting file, go to the Edit menu, select the active file
and change the settings.

12.5 Auto Image
What can be done ?
Auto Image creates the best suited image file for the connected source.
It calculates/measures several source parameters :
• Total pixels per line
• Start pixel
• Phase
• Contrast/Brightness levels
Auto Image works only for data images.
The measure of the total number of pixels per line can be done through 2 methods
• Limited scan: a windowing is used to allow fast tracking.
The operation takes about 20 seconds (depending on file)
• Full scan: tracking is done over the full range.
The operation takes about 1.5 minutes (depending onfile)

12.6.2 Correct file parameters
What is already available during start up ?
During the installation of a file with LOAD, the horizontal period, the total number of vertical lines and the interlaced mode are
automatically measured and filled in. These values will be available when starting up the EDIT procedure of an active file.
Adjustable items
• Active horizontal pixels : determine the width of the window on the screen. This value is normally given in the source specifi-
cations. If not, adjust until full image is displayed (no missing pixels).
• Horizontal start in pixels : number of pixels between the beginning of the input signal and the start of the video information in
the signal.
• Horizontal period in ns : when active file, the correct value will be filled out.
• Active vertical lines : number of horizontal lines determining the height of the projected image. this value is normally given in
the specification of the source. If not, adjust until full image height is displayed (no missing lines).
• Vertical start in lines : number of lines between the start of the input signal and start of the image on the screen.

TheComb filteris by default enabled.
TheAGC hold intervalis the time interval in which the AGC is inhibited (AGC hold = no update in video amplitude measurement),
the advanced parameter allows to choose a short or long hold interval.
A long AGC hold interval eliminates Macrovision
®disturbances since the AGC is hold during a long interval, thus reducing the
probabilityto encounter a Macrovision®pulse.
Thesync locking settingis recommended for poor video signals (ex: poor TV signals).
Sharpnessadjustment can be chosen to be coarse or fine.
It is recommended to use the default values.

TheVCO rangesetting determines the frequency range of the VCO (Voltage Controlled Oscillator).
TheCpmp(Charge pump current) sets the low pass filter current.
Both VCO range & Cpmp are set by the image file, changing these settings is only indicated in for special purposes.
Thehorizontal sync polaritysetting can be useful in case of a bad shaped edge, one can choose between the leading (active low)
or trailing (active high) edge.
The input format settings are used to tell more about the signals connected on the BNC’s, it completes the information in the source
selection menu.
- RGB is selectedby default and means that an RGB signal is connected to the BNC’s
- PR/Y/PB must be selected whenever:
• a progressive signal (32 kHz frequency video signal )is connected to the BNC’s (select the source withData on BNC’sin the
Source selection menu).
• one wants (in PiP mode) to visualize the component video signal in a Data window hereby adding a video image in the PiP
layout.
-HDTV-PR/Y/PB for high definition component video signals.
It is recommended to use the default values.
