ADDRESS NAME BITS
FUNCTION
13h
8 The first target area of automatic white balance control in plus direction of high-
speed mode.
KGBGR2
In the case that white balance control data is within (data of address 12h + data of
address 13h), high-speed mode control is completed and then changed to normal-
speed control mode.
14h
8 The second target area of automatic white balance control in minus direction of
KGBGR3
high-speed mode.
In the case that white balance control data is over (data of address 14h + data of
address 15h), high-speed mode control is restarted.
15h
8 The second target area of automatic white balance control in plus direction of high-
KGBGR4
speed mode.
In the case that white balance control data is over (data of address 14h + data of
address 15h), high-speed mode control is restarted.
16h LIMIM
8 Limitation in making white balance data at minus I-axis.
17h LIMIP
8 Limitation in making white balance data at plus I-axis.
18h LIMQM
8 Limitation in making white balance data at minus Q-axis.
19h LIMQP
8 Limitation in making white balance data at plus Q-axis.
1Ah
YLCL
8 Limitation in making white balance data. A pixel with lower luminance level than
data of this address is neglected.
1Bh
YHCL
8 Limitation in making white balance data. A pixel with higher luminance level than
data of this address is neglected.
1Ch
7 The first target area of auto white balance control in minus I-axis. In the case that
LIMWIIM
white balance control data is within the area by address 1Ch, 1Dh, 1Eh and 1Fh,
automatic white balance control is completed.
1Dh LIMWIIP 7 The first target area of auto white balance control in plus I-axis.
1Eh LIMWIQM 7 The first target area of auto white balance control in minus Q-axis.
1Fh LIMWIQP 7 The first target area of auto white balance control in plus Q-axis.
20h
7 The second target area of auto white balance control in I-axis. In the case that
LIMWOI
white balance control data is over the area by address 20h and 21h, automatic
white balance control is restarted.
21h
7 The second target area of auto white balance control in Q-axis. In the case that
LIMWOQ
white balance control data is over the area by address 20h and 21h, automatic
white balance control is restarted.
22h WBR_MAX 8 Maximum gain of red signal in automatic white balance control.
23h WBR_MIN 8 Minimum gain of red signal in automatic white balance control.
24h WBB_MAX 8 Maximum gain of blue signal in automatic white balance control.
25h WBB_MIN 8 Minimum gain of blue signal in automatic white balance control.
26h WBR1
8 White balance preset 1 : Red signal gain
27h WBB1
8 White balance preset 1 : Blue signal gain
28h WBR2
8 White balance preset 2 : Red signal gain
29h WBB2
8 White balance preset 2 : Blue signal gain
