7.3.8 Input Balance

Why adjusting the input balance?

The input balance is normally correct adjusted in the factory. But due to signal distribution or signal transmission, a color imbalance can be the result. This imbalance can be adjusted source by source for color critical applications. These adjustments influence only the actual custom adjustment file. This procedure is not so easy.

Before starting the Input Balance function, generate a signal with dominant full black and full white areas.

Step to be taken

To adjust the input balance, the following steps have to be executed in the following order :

1.Start with the black balance.

2.Continue with the white balance.

The default values are normally loaded when selecting a source. If the image is not as desired, continue with the next procedure.
