7.3 Color Enhancement Features
Due to the presence of a Bayer filter in the color cameras (see Section 7.1 on page 155), the pixel
values read out from the sensor reside in RGB color space. And for each pixel, the pixel value for
only one color (red, green or blue) will be available ("raw" data).
The color enhancement features, however, require that red, green, and blue pixel values are
available for each pixel.
To meet this requirement, automatic demosaicing is executed on the raw data before any color
enhancement feature will process pixel data. The automatic process is also called a color
transformation from RGB color space to RGB color space.
Note: All color enhancements described in this section are performed on pixel data in RGB color
space, regardless of the pixel format chosen for pixel data output to the PC.
7.3.1 Balance White
The balance white feature allows you to perform white balancing. The feature acts on data triplets
that are available for each pixel and reside in the RGB color space. So the feature lets you perform
red, green, and blue adjustments for each pixel such that white objects in the camera’s field of view
appear white in the acquired images.
If color binning is enabled for the acA1920-25uc, white balancing will be applied
after color binning was performed. For more information about color binning, see
Section 8.6.2 on page 193.
