If only offset and hot pixel correction is needed it is not necessary to calibrate a
gray image. (see Calculate)
Gain Correction: The gain correction is based on a gray reference image, which is taken at
uniform illumination to give an image with a mid gray level.
Gain correction is not a trivial feature. The quality of the gray reference image
is crucial for proper gain correction.
Produce a gray image with an average between 2200 and 3600DN. Click on the Validation
button to check the average. If the average is in range, the Set Grey Ref button is active.
Calculate: Calculate the correction values into the camera RAM. To make the correction values
permanent, use the 'Save to Flash' button.
Save to Flash: Save the current correction values to the internal flash memory.
This will overwrite the factory presets.
