Table 13: Driver Variables−Auto White Balance (ID = 3)
Offs Name Type Default RW Description
0vmtvoid*
59731 RW Reserved
2 windowPos uchar
0 RW Position of upper left corner of AWB window
Bits [3:0]
—X0 in units of 1/16th of frame width
Bits [7:4]—Y0 in units 1/16th of frame height
New position written to this variable takes effect only after
REFRESH_MODE command is given to the sequencer (seq.cmd is
set to 6).
3 windowSize uchar
0xEF RW Dimensions of AWB window
Bits [3:0]
—width (in units of 1/16th of frame width)
decremented by 1.
Bits [7:4]
—height (in units of 1/16th of frame height)
decremented by 1.
New dimensions written to this variable take effect only after
REFRESH_MODE command is given to the sequencer (seq.cmd is
set to 6).
4 wakeUpLine uint
R Number of image row at which MCU wakes up to perform AWB
calculations. This number is automatically adjusted after each
change of the position and dimensions of the AWB window.
6 ccmL[0] int
0x0219 RW Left color correction matrix element K11. Value is encoded in
signed two’s complement form; 256 means 1.0. New values
written to awb.ccmL array take effect only after REFRESH
command is given to the sequencer (seq.cmd is set to 5).
8 ccmL[1] int
0xFEEC RW Left color correction matrix element K12
10 ccmL[2] int
0xFFFF RW Left color correction matrix element K13
12 ccmL[3] int
0xFF6A RW Left color correction matrix element K21
14 ccmL[4] int
0x01D4 RW Left color correction matrix element K22
16 ccmL[5] int
0xFFC9 RW Left color correction matrix element K23
18 ccmL[6] int
0xFF71 RW Left color correction matrix element K31
20 ccmL[7] int
0xFDD3 RW Left color correction matrix element K32
22 ccmL[8] int
0x03ED RW Left color correction matrix element K33
24 ccmL[9] int
0x0020 RW Left color correction matrix red/green gain ratio.
Value is interpreted as unsigned; 32 means 1.0.
26 ccmL[10] int
0x0035 RW Left color correction matrix blue/green gain ratio.
Value is interpreted as unsigned; 32 means 1.0.
28 ccmRL[0] int
0xFF92 RW Delta color correction matrix element D11. Value is encoded in
signed two’s complement form; 256 means 1.0. New values
written to awb.ccmRL array take effect only after REFRESH
command is given to the sequencer (seq.cmd is set to 5).
30 ccmRL[1] int
0x0098 RW Delta color correction matrix element D12
32 ccmRL[2] int
0xFFE1 RW Delta color correction matrix element D13
34 ccmRL[3] int 0x0014
RW Delta color correction matrix element D21
36 ccmRL[4] int 0xFFFC
RW Delta color correction matrix element D22
38 ccmRL[5] int 0xFFF2
RW Delta color correction matrix element D23
40 ccmRL[6] int 0x004E
RW Delta color correction matrix element D31
42 ccmRL[7] int 0x0148
