The results are expressed on a logarithmic scale. The Black Noise test measures aberrant noise introduced by the internal circuitry, as well as flaws in and contamination of the optical system. Ghosting is a faint false image rendered next to the actual image. The results are reported in terms of gray-level deviation in the ghosted area. The Color Registration test measures the accuracy of the alignment of the CCD array's red, green, and blue planes.
Proper alignment is necessary to produce clean edges between colors.
The results, presented in pixels, describe the maximum distance between any two misaligned planes.
