For best results, ensure that:
• 50 or 60 Hz ambient light flicker is sufficiently low not to affect camera performance
and calibration results.
• For best results, the analog gain should be adjusted for the expected operating
conditions and the ratio of the brightest to darkest pixel in a tap should be less than 3
to 1 where:
• The camera is capable of operating under a range of 8 to 1, but will clip values larger
than this ratio.
• The brightest pixel should be slightly below the target output.
• When 6.25% of pixels from a single row within the region of interest are clipped, flat
field correction results may be inaccurate.
• Correction results are valid only for the current analog gain and offset values. If you
change these values, it is recommended that you recalculate your coefficients.
