White-Balance, Luminance Adjustment
Approximately 30 minutes should be allowed for warm up before proceeding white balance adjustment. Before started adjust white balance , please set the Chroma-7120 MEM Channel 3 to Reddish (5800K) color, MEM Channel 4 to Normal (6500K) color, MEM Channel 9 to Bluish (9300K) color , and MEM Channel 10 to sRGB color ( our Reddish color parameter is x = 326 ±20, y = 342 ±20, Y≥200±20cd/m2; Normal color parameter is x = 313±20, y = 329 ±20, Y≥220±20cd/m2; Bluish color parameter is x = 283 ±20, y = 297 ±20, Y≥180±20cd/m2 ; sRGB color parameter is x = 313 ±30, y = 329 ±30, Y=200±20cd/m2)
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 .
