Frame dimension parameter host inputs

5.3.6

White balance controls

Table 15.

Frame dimension parameter host inputs

Index

FrameDimensionParameterHostInputs register

0x85fa

bLightingFrequency_Hz

Default value

0x64

Purpose

AC Frequency - used for flicker free time period calculations this mains

frequency determines the flicker free time period.

Type

BYTE

Possible values

0 to 255

Note: The value is double the desire frequency in Hz.

i.e. 0x64 = 100 which equates to 50 Hz.

Table 16.

White balance controls

Index

WhiteBalanceControls register

0x8652

bMode

Default value

0x00

Purpose

Disables the GUI

Type

CODED

Possible values

<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_COLOUR_TEMP

<9> FLASHGUN_PRESET

0x8653

bManualRedGain

Default value

0x00

Purpose

User setting for Red Channel gain.

Type

BYTE

Possible values

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
