Static Contrast Mode (Fixed Range of DN Values)
This is the camera operation used when the feature
static contrast mode maps a fixed range in the 16-bit image to 8-bit values. The
minimum and maximum input values (contrastMinValue and contrastMaxValue
features) specify the range of values in the 16-bit image. If the image scene contents
are known to always fall within a specific range, this mode can be used to provide
consistent mapping of values.
Note: If the image pixel data moves outside this range, the information
is lost and rendered as either 0 or 255 (pixel data below the range is
mapped to 0, above the range mapped to 255).
For example, in the following image, the 16-bit histogram shows that the pixel range
between the minimum and maximum values present is 3002 DN.
