Definition of the "Test Conditions"
7.4.1
Optics
G
No Lens or IR filter
G
No dirt on sensor glass
7.4.2
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:
1
Mean: (45% of full scale) < Mean < (65% of full scale). Ideal luminosity (mid grey) = 50-60% of
full scale.
2
Standard Deviation: Standard Deviation < 10.
7.5
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:
