fpCompiledExposureTime_us
Purpose
Type
Time in µsecond that the system uses
FLOAT
fpFinalDesiredExposureTime_us
Purpose
Type
Absolute time in µsecond that the system would like to use for correct
exposure, this is the value which is used to control the dampers

White balance control
Table 29. White balance control
Index
WBControlParameters⁽¹⁾
bWhiteBalanceMode
0x1380
Default value
Purpose
Type
possible values
<1> AUTOMATIC
For setting Mode of the white balance
CODED
<0> OFF - No White balance, all gains will be unity in this mode
<1> AUTOMATIC - Automatic mode, relative step is computed here
<3> MANUAL_RGB - User manual mode, gains are applied manually
<4> DAYLIGHT_PRESET - DAYLIGHT and all the modes below, fixed
value of gains are applied here.
<5> TUNGSTEN_PRESET
<6> FLUORESCENT_PRESET
<7> HORIZON_PRESET
<8> MANUAL_color_TEMP
<9> FLASHGUN_PRESET
bManualRedGain
0x1382
Default value
Purpose
Type
possible values
0x00
User setting for Red Channel gain
BYTE
0 to 255
Applied_Red_Gain = (1 + bManualRedGain / 128) / MinGain
Where MinGain = the smallest value from either Applied_Red_Gain,
Applied_Green_Gain or Applied_Blue_Gain
