3.3. Sharpness
The sharpness control feature may be used to compensate low-pass effects caused for instance by the special color
interpolation. If you do not prefer such signal manipulation, you may switch it OFF.
For sharpness control inquiry and status register, follow the same definition as “BRIGHTNESS”.
3.4. White Balance
Color models have the white balance feature which can be controlled automatically or manually, U/R(Red/Green)
and V/B(Green/Blue) alter the degree to which Red and Blue CCD component pixels are weighed to form composite
pixels. In manual mode you can adjust the white balance by altering the Blue(U/V) and Red Value(V/R). In
addition, the one push white balance option can be used for a non-interactive calibration.
