[ 0 ] Color Interpolation Function Enable
[R/W]
This bit specifies whether color interpolation is processed or not. Color
interpolation methods are defined by OP_MODE register. Most importantly, in
order to have a correct color interpolation, the first input pixel data type should
be R pixel data.
1 : Interpolation ON, 0 : Interpolation OFF
* Note : The start pixel of every input frame must be R for proper interpolation.

[ 7..0 ] Scale Width Control Lower Value
[R/W]
* Note : The scale width control register is only related to operating mode
CIF/SIF/QCIF/QSIF, and controls how many column data in each line are output.
Default value is 140h(340d), the half of standard VGA width size.
8.2.2. Color Matrix Coefficients Value[8Ah ~ 95h]
These registers are used in color matrix function in order to compensates color spread
effect of color filters and sensing circuits to get the optimal pure color reproduction.
Color matrix coefficients are programmable from -127/64 to 127/64. Programming
register value for intended color matrix coefficients should be resolved by the following
sequence.
For positive values,
CMAxx = Integer(RealCoefficientValue x 64);
For negative values,
CMAxx = TwosComplement(Integer(RealCoefficientValue x 64));
RealCoefficientValue values from -127/64 to 127/64 can be programmed.
Offset compensation registers are also supported.
