2. Contrast Enhancement
Two features to maximize the use of the output dynamic range (especially when pixel format is less than
12 bits). Typical use is to subtract minimum pixel value expected and then gain up maximum pixel value
to approach full scale.
Offset
1. Single value added to each pixel
2. Range -512 to 511 DN, scaled down according to pixel format
3. Positive values may be used to measure dark noise
Gain
1. Floating point digital multiplier applied to each pixel
2. Range 1x to 10x
1. Save average line (of "flatfieldCalibrationSampleSize" rows).
This is the first user correction applied – it is subtracted from
each line.
2. This feature may not be of use to many users as the camera
already subtracts true "dark current", but it may be useful for
some to provide a per pixel offset correction.
3. Range 0 to 511 DN, 12 bit
4. Default value is 0 DN for each pixel
1. Use "flatfieldCorrectionAlgorithm" to calculate the per pixel
gain to achieve the specified target output.
2. Range 0 to 15.9998x
3. Default 1x
