Weight for Horizontal Decimation
X output = int (X input/2048*reg. value). Value is calculated and overwritten by mode
driver (ID = 7).

Weight for Vertical Decimation
Y output = int (Y input/2048*reg. value). Value is calculated and overwritten by mode
driver (ID = 7).
InputSize is defined by Registers 17–20. Minimal output size supported by the decimator is 3 x 1 pixel.

Luminance Range of Pixels Considered in WB Statistics
7:0 20
Lower limit of luminance for WB statistics.
15:8 200
Upper limit of luminance for WB statistics.
In order to avoid skewing WB statistics by very dark or very bright values, this register allows programming the
luminance range of pixels to be used for WB computation.

Right/Left Coordinates of AWB Measurement Window
7:0 0
Left window boundary.
15:8 80
Right window boundary.
This register specifies the right/left coordinates of the window used by AWB measurement engine. The values
programmed in the registers are desired boundaries divided by 8.

15:0 0x3C00
Bottom/Top Coordinates of AWB Measurement Window
7:0 0
Top window boundary.
15:8 60
Bottom window boundary.
This register specifies the bottom/top coordinates of the window used by AWB measurement engine. The values
programmed in the registers are desired boundaries divided by 8.

Red Chrominance Measure Calculated by AWB
This register contains a measure of red chrominance obtained using AWB measurement algorithm. The measure
is normalized to an arbitrary maximum value; the same for R48:1, R49:1, and R50:1. Because of this
normalization, only the ratios of values of registers R48:1 R49:1, and R50:1 should be used.

7:0 R/O
Luminance Measure Calculated by AWB
This register contains a measure of image luminance obtained using AWB measurement algorithm. The measure
is normalized to an arbitrary maximum value; the same for R48:1, R49:1, and R50:1. Because of this
normalization, only the ratios of values of registers R48:1, R49:1, and R50:1 should be used.

Blue Chrominance Measure Calculated by AWB
This register contains a measure of blue chrominance obtained using AWB measurement algorithm. The measure
is normalized to an arbitrary maximum value; the same for R48:1, R49:1, and R50:1. Because of this
normalization, only the ratios of values of registers R48:1, R49:1, and R50:1 should be used.
