The Trim menu allows you to correct subtle issues in the individual color difference
channels with offset and gain controls. The offset controls adjust the DC offsets above or
below the nominal points. This can be used to correct black balance errors. The gain
controls adjust the amplitude of each channel. It is helpful to set the output of the module
to Split Screen (in the Vid Out menu) to allow viewing a comparison of the processed
signal to the input while adjusting the controls below.
Use the controls described below to make the offset and gain corrections:
•
Cb Offset – adjust the DC offset of the Cb channel to between ± 300.
•
Cr Offset – adjust the DC offset of the Cr channel to between ± 300.
•
Cb Gain – adjust the amplitude of the Cb channel to between ± 20.
•
Cr Offset – adjust the amplitude of the Cr channel to between ± 20.
