Definition of the "Test Conditions"
Optics
Illumination and uniformity of scene
No lens should be used. The intensity of required illumination and the uniformity of the scene can be
defined thus. A defect-free image should give a luminosity histogramme (8 bits resolution) with the
following statistics:
Definition of a "Major Visible Defect"
Anything which is visible with the naked eye under the conditions described, is worthy of further
investigation. For example:
1 Mean: (45% of full scale) < Mean < (65% of full scale). Ideal luminosity (mid grey) = 50-60% of
2 Standard Deviation: Standard Deviation < 10.
