Pixel fault definitions
Pixel fault numbering convention
Please find the pixel notation described in
describes 9 Bayer pixels of a common color, that is all the pixels will either be Red, Green or Blue.
The pixel under test is X.
Single pixel faults
STMicroelectronics define a single pixel fail as a failing pixel with no adjacent failing neighbors of the
same colour. A single pixel fail can be a “stuck at white” where the output of the pixel is permanently
saturated regardless of the level of incident light and exposure level, a “stuck at black” where the
pixel output is zero regardless of the level of incident light and exposure level or simply a pixel that
differs from its immediate neighbors by more than the test threshold, that is differ by more than 8.0%
from pixel average of color space neighbors.
In the example below in
single pixel fail if the pixels at positions [0],[1],[2],[3],[4],[5],[6] and [7] are “good” pixels that pass the
final test. The implemented test program qualifies a sensor with up to 120 single pixel faults. Defect
correction algorithms correct the single pixel faults in the final image.
