4.3. Advanced functions in the Settings menu
The Settings menu contains the following advanced functions:
Lookup Table
The display contains a number of factory-defined and user-defined
Lookup Tables (LUTs).
Turn the control wheel to select a LUT.
- Select a DICOM lookup table for most medical viewing
applications. The DICOM function results in more visible grayscales
in the images.
- Select a CRT (gamma) lookup table in case the display is used to
replace a CRT display.
- LUT 3 and LUT 4 are user-programmable lookup tables (dedicated
software needed).
- If you select None, no LUT will be selected.
- The selection Test LUT is meant for internal test purposes. It
should not be selected for normal operation.
Input Mode
To change the Input Mode setting, click the control wheel. Turn the
wheel to select Standard or Extended input mode. Then click the wheel
again to enter the selected submenu.
The following input mode settings can be selected:
Standard input mode
RGB->Y................... The RGB video signals from the imaging board
are calculated and transformed into a single
luminance value according to the formula
0.3R + 0.59G + 0.11B. This single luminance
signal drives the RGB sub-pixels of the panel
equally.
Use this setting in case the imaging board is a
color board.
RGB->RGB ............. The R video signal drives the R sub-pixels, the G
video signal drives the G sub-pixels and the B
video signal drives the B sub-pixels. This is the
preferred setting for grayscale imaging boards
that have the luminance signal on all 3 video
channels, because it ensures the most levels of
gray.
