Definition of cosmetic specifications
Hot pixel defect
Pixel whose signal, in dark, deviates by more than 400 DN (10 bits) from the average of all
the pixels.
Single pixel defect
Pixel whose signal, at nominal light (illumination at 50% of saturation), deviates by more
than ±30% from its neighboring pixels.
Cluster defect
A grouping of at most 8 pixel defects within an area of 3 x 3 pixels.
Spot defect
A grouping of 9 pixel defects within an area of 3 x 3 pixels.
Column defect
A column which has 12 pixel defects in a 1*12 kernel.
Row defect
An horizontal grouping of more than 4 pixel defects between at least 2 good pixels on
both sides, where single good pixels between 2 defective pixels are considered defective.
Test conditions
•
Digital gain – 1X.
•
Nominal light = illumination at 50% of saturation.
•
Frame Rate = 60 fps (Falcon 4M60), 30 fps (Falcon 4M30)
•
Integration time = 15 ms
•
Ambient Temperature of 25°C
Note:
While the number of clusters is not limited by a maximum number, the total
number of defective pixels cannot exceed 100. Therefore, you could have 12 clusters of 8
in size (12 x 8 = 96), but you could not have 13 clusters of 8 in size (13 x 8 = 104).
The probability of 12 clusters of 8 is negligible and is only used as an example.
