White Shading Compensation

The camera can use DEFAULT (fixed value) and three user adjustable functions (USER1, USER2, USER3) to store white shading compensation data.

Select SHADING SELECT in the setting menu LENS SETUP screen to set compensation data. Selecting OFF turns off shading compensation.

NOTE

If white shading adjustments are made while the video image is distorted due to GENLOCK, the adjustments may not be correct. Wait for the video image to return to normal before performing white shading adjustments again.
