Figure 6-5 Gamma Section of the Software
6.6.1.Gamma Coefficients GC(0-8)
The 9 boxes in the Gamma section represent the 9 segment piece-wise-linear
function that defines the gamma curve. These 9 values are used to calculate the
256 element look-up-table (LUT) that is required to transform input video data into a
gamma-corrected data signal for the microdisplay input port. The “Read” button will
retrieve the current 9 values from the microcontroller. The user can change any of the 9
values and see the resulting gamma corrected video by pressing the “Write” button.
6.6.2.Using “Update LUT” Button for Auto-Gamma Correction
The software allows for the immediate update of the gamma tables with the push
of a button, “Update LUT”. This button, located in the center of the software
form, tells the firmware to calculate the Gamma coefficients using the VGN
signal provided by the DSVGA microdisplay. This feature allows the display
gamma to be automatically adjusted for any operating conditions of temperature
and brightness. The firmware calculates the 9 Gamma coefficients and then the
full 256 value lookup table. This lookup table is then loaded, by the firmware,
into the DSVGA Microdisplay.

6.6.3.Loading the LUT from a file
The software allows for the loading of the gamma tables from a text file. The
format is as follows;

.
.
1023
Each of the 256 values is on a separate line. This lookup table is then loaded, by
the firmware, into the display.
6.6.4.The “Read LUT” Button
The software allows for the reading of the full 256 values of the LUT using this
button. The result is displayed in the message box at the bottom of the software.
The user can scroll through all the values or select and save to a text file. These
LUT values are the values before being gray-coded.
6.6.5.System Gamma
The software allows for the overall System Gamma to be set between 0.5 and 2.5
when using the Auto-Gamma feature. This System Gamma can be used to
compensate for the gamma of the input video. For example, if the source video is
gamma corrected to 2 then setting the System Gamma to 1.9 and pressing the
“Set” button will give a better overall gamma response. This does not mean that
there is a 1 to 1 relationship between input gamma and the System Gamma.
Figures 6-6 to 6-8 show the grayscale response for a display at several luminance
settings obtained by using the “Update LUT” feature and the System Gamma set
to 1.
