3.3. Sharpness
This feature controls sharpness by enhancing the edges of image. By applying this feature the edge of the images is
sharpened against the ambient noise, which makes it more visible. The user can control the desirable level to obtain
the best result. If you do not prefer such signal manipulation, you may switch it OFF or set its value to ‘10’ (a value
of ’10’ equals turning OFF Sharpness).
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 and Red Value. One push white balance option
can be used for a non-interactive calibration in addition. Currently automatic white balance features are not supported.
