Figure 4-32 ME2P-2621-15U3M/C \ ME2P-2622-15U3M/C sensor spectral response
Note: ME2P-2622-15U3M/C is the Grade2 sensor, and ME2P-2621-15U3M/C is the Grade1 sensor. The
only difference between the two cameras is the grade of the sensor. The difference between Grade1 and
Grade2 sensors defined by sensor manufacturers is: Grade1 have no consecutive defect pixel cluster, and
Grade2 may have up to 12 consecutive defect pixel cluster. The camera has static defect pixel correction
function, and it will calibrated for the default factory parameters. If the scene parameters are changed, you
can use the static defect pixel correction plugin to re-calibrate. For details please see section 9.3.
1)
Monochrome camera
As shown below, cluster with 4 consecutive defect pixels in a row is not allowed (NOK).

Color camera
Examples 1: Cluster with 4 consecutive defect pixels within the same Bayer color plane in a row is not
allowed.
