Automatic Gamma correction
Gamma correction, or often simply gamma, is the name of a nonlinear operation used to encode and decode
luminance or tristimulus values in video or still image systems.
You need adjust 4+3 gamma for different samples based on the color coordinates and target gamma offered by PQ
engineer. So each sample can get almost the same effect as PQ golden sample. The 4+3 gamma include 4 gamma
based on 4 different color temperature (cool, normal, warm1, warm2) and 3 gamma related to SDR to HDR (cool,
normal, warm).
For the automatic gamma correction, we can do as below, but please refer to
“Gamma correction specification
(v1.00)”
for detail.
▪Initialize the picture, turn off dynamic backlight, dynamic contrast, and set picture mode as computer desktop
mode;
▪
Get the color coordinates (x, y, Y) and target gamma in the PDM of the target model;
▪
Open the factory menu of TV, Open the tools
SIACP
and
main.vi
on the PC, connect the equipment correctly
(CA310, serial port, PC, TV);
▪ Fill the color coordinates (x, y, Y) target gamma, error range and time-delay in the main.vi tool that made by AOE,
and save it;
