3.3.2 DCC1545M Application Notes

For the technical specifications of this model go to: Camera and sensor data >
Sensor
Sensor speed does not increase for AOI width <240 pixels.
Extreme overexposure shifts the black level. Please deactivate the
At very long exposure times and minimum gain, the white level may not be reached. The gain should be
increased by one step in this case.
Monochrome version only: The sensor internally works like the color version. This might lead to artifacts when
subsampling is used.
The brightness of the first and last line might deviate due to the sensor.
Gain values between 59 and 99 may lead to image inhomogeneity.
When using very narrow AOIs, the sensor may not be able to calculate the correct black level. Use manual black
level offset when problems with the black level occur.
Calibration
Cameras with a date of manufacture
calibration corrects offset errors when gain is used. In calibrated cameras, automatic black level correction is
disabled by default. The calibration can only be used with uc480 driver version 3.31 or higher.
Cameras with a date of manufacture
and horizontal lines may become visible. High gain values may shift the black level and therefore should be
avoided.
Offset increases the black level every 7th step. The steps in-between change the appearance of fixed pattern
noise.

3.3.3 DCC1645C Application Notes

For the technical specifications of this model go to: Camera and sensor data >
Sensor
At very long exposure times and minimum gain, the white level may not be reached. The gain should be
increased by one step in this case.
The RGB gain controls have no effect for values >90.

3.3.4 DCU223x Application Notes

For the technical specifications of this model go to: Camera and sensor data >
Sensor
Long exposure times will increase the number of hotpixels.
High temperatures will increase the black level of individual pixels.

3.3.5 DCU224x Application Notes

For the technical specifications of this model go to: Camera and sensor data >
Sensor
Long exposure times will increase the number of hotpixels.
High temperatures will increase the black level of individual pixels.
When vertical 4x binning is activated, the minimum image width increases to 640 pixels.
