9.White- Balance, Luminance Adjustment Approximately 30 minutes should be allowed for warm up before proceeding white balance adjustment. How to setting MEM channel you can reference to chroma 7120 user guide or simple use “SC” key and “NEXT” Key to modify xyY value and use “ID” key to modify the TEXT description Following is the procedure to do white-balance adjust . 1. Setting the color temp. A. 6500K: x=313±20 ,y=329±20 Warm color temp. parameter is B. 7300K Normal color temp.
C. Adjust Cool (9300K) color-temperature 1. Switch the Chroma-7120 to RGB-Mode (with press “MODE” button) 2. Switch the MEM. Channel to Channel 9 (with up or down arrow on chroma 7120) 3. The LCD-indicator on chroma 7120 will show x=283±20,y=297±20 4. Adjust the RED on factory window until chroma 7120 indicator reached the value R=100 5. Adjust the GREEN on factory window until chroma 7120 indicator reached the value G=100 6.
