Precautions When Using Digital Shift

There are several checks and precautions that you must follow before using the digital shift feature.
The checks and precautions differ depending on whether the camera will be set for a 12 bit pixel
format or for an 8 bit pixel format in your application.
If you will be using a 12 bit pixel format, make this check:
Use the pylon Viewer or the pylon API to set the camera for a 12 bit pixel format and no digital shift.
Check the output of the camera under your normal lighting conditions and note the readings for the
brightest pixels.
If any of the readings are above 2048, do not use digital shift.

If all of the readings are below 2048, you can safely use the shift by 1 setting.

If all of the readings are below 1024, you can safely use the shift by 1 or 2 settings.

If all of the readings are below 512, you can safely use the shift by 1, 2, or 3 settings.

If all of the readings are below 256, you can safely use the shift by 1, 2, 3, or 4 settings.

If you will be using an 8 bit format, make this check:

Check the output of the camera under your normal lighting conditions and note the readings for the
brightest pixels.
