White Balance Calibration
< @WB >
The EZ Match Imager’s factory default values are appropriate for nearly all applications.
However, the
White Balance calibration command will override the pre-configured values
if necessary.
White Balance is a processing operation performed to ensure proper color fidelity in a
captured digital image. The image sensor does not detect light in exactly the same way as
the human eye, which means that some processing or correction of the detected image is
necessary to ensure that the final image realistically represents the colors of the original
image.
White Balance calibration works best if a white object (a piece of paper, for example) is
placed in front of the imager. White and black objects can be present in the field of view
during White Balance calibration, but no color objects can be present.
Important: The White Balance correction adjusts the R , G , and B gain offset values for
every possible analog gain (0 to 42) in the system. Any gain values greater than 42 (43 to
48) will use the factory default White Balance settings.
