Ⅳ. ADJUSTMENT
8. AWB H
A. Purpose
To get the proper White Balance for the Preset mode (daylight, cloudy, tungsten, fluorescent low, fluorescent high),
get the R/B gain from the Low Temperature and High Temperature standard light source and adjust the White
Balance.And by getting the proper adjustment data of each mode, do the AWB algorithm and compensate the
differences.
B. Behavior
◆
Adjusting the AWB High Temp
[Description of the algorithm]
In 5000~6000K color temperature of Daylight light source, get the ideal WB gain and calculate
AWB key parameter of parts of High temperature by the linear conversion
[Standards for the Adjustment]
- Specification of the tools: 36% Reflect board or page, Dark room
- Color temperature : 6100K±50 (No light sources are required. Using the flash)
- Brightness : Proper exposure are required when firing the flash
- Distance between the camera and tool : 80cm
①
After completing the Flash exposure adjustment, the procedure starts.
②
The camera sets as Auto Program mode, AWB Auto, EV 0 , ISO 100 , Flash Fill-in mode, zoom Wide by the
script file.
③
WB data can get from the average of the R/B gain that comes from the several images. (5 images are standard
so far)
C. Spec (Standard for checking defect)
- This is maximum standard by PV3 and can be changed in the PR stage.
658 < Rgain < 808
273 < Bgain < 343
