Taking Dropped Pixels Into Account; Enabling Shading Correction - Basler L100k User Manual

Operation and Features

3.6.3.2 Taking Dropped Pixels into Account

In many cases, when a frame grabber is receiving pixel data for a captured line, the grabber drops
the data for the first few pixels. Since you have used captured pixel data from the frame grabber
to create the shading table, you must make sure that at the beginning of your shading data, you
fill in a dummy correction value for every pixel dropped by the frame grabber.
You can use Test Image One (see Section 3.9.1), consult the documentation for your frame
grabber, or speak to your frame grabber manufacturer to determine the number of pixels that the
grabber misses at the start of each line. Use this value to determine the dummy correction values
that must be added to the sdahing correction data that you upload to the camera. For example, if
your grabber misses 5 pixels at the beginning of each line, add 5 dummy correction values before
the actual correction values (see Figure 3-9).
