rw: Blue gain control
BLU<6:0> - white balance value for the blue channel.
The formula is:
Blue_gain=1+(BLU<7:0> - [80])/[100]; range (0.5x ~ 1.5x).
BLU<7> - Sign bit. If “1”, Blue gain increase; “0” gain decrease.
Register 02 - rw: Red gain control
RED<6:0> - white balance value for the red channel.
The formula is:
Red_gain=1+(RED<7:0> - [80])/[100]; range (0.5x ~ 1.5x).
RED<7> - Sign bit. If “1”, Red channel gain increase; “0” gain decrease.
SAT<7:0> - saturation adjustment for the UV channel based on the default setting;
range (-4dB ~ +6dB). If SAT<7:0> > [80], increase; if SAT<7:0> < [80], decrease.
Register 04 & 05
-
w: Reserved Register
This register is reserved for internal test use. Write data to this register will be no function.
BRT<7:0> - brightness adjustment for the Y/RGB channel based on the default setting;
range (-200mv ~ +200mv). If BRT<7:0> > [80], brightness increase; If BRT<7:0> < [80], bright-
ness decrease. This register is auto/manual controllable. If register 2D bit 4=1, this register is
controlled by chip automatically, if write value to this register, this value will be updated by
internal circuit. Only when register 2D bit 4=0, this register can be set to any value
