The Calibir GigE Image Format controls, as shown by CamExpert, groups parameters used to
configure camera pixel format, image processing, overlays, and so forth. Additionally a feature
control to select and output an internal test image simplifies qualifying a camera setup.

Table 16 describes these features along with their view attribute. Additionally the view column will
indicate which feature is a member of the DALSA Features Naming Convention (denoted by DFNC),
versus the GenICam Standard Features Naming Convention (SFNC tag is not shown).

Contrast
rangeCompressionContrast
When the output pixel format is 8-bits, the range
compression contrast setting determines the range
of values in the 14-bit image that are mapped to 8-
bit output. The higher the contrast, the more the
values are stretched across the 8-bit range. When
contrast is set to the maximum value (255), the
image is effectively binarized.

Contrast Limit Mode
rangeCompressionContrastLimitMode
When enabled, and the scene contains very little
contrast, the amount of contrast stretching is
limited. This reduces noise amplification. Higher
values result in less contrast stretching than
typically applied using the Range Compression
Contrast value.
