1. RS = Rolling Shutter, GS = Global Shutter.
2. For the color devices, all bright defects are defined within a single color plane, each color plane is tested.
3. Cluster defects are separated by no less than two good pixels in any direction.
4. Rolling Shutter Dark Field points are dominated by photodiode integration time, Global Shutter Dark Field defects are dominated by the
readout time.
5. The net sum of all bright and dark field pixel defects in rolling and global shutter are combined and then compared to the test limit.
Defect Map
The defect map supplied with each sensor is based upon
testing at an ambient (29
°
C) temperature. All defective
pixels are reference to pixel (0, 0) in the defect maps. See
Figure 11 for the location of pixel (0, 0).
