3.3 White balance adjustment processes
The set should be working above 30 minutes before white balance adjustment for it would be in a
stabler state. Use white balance apparatus CA-210 and switch to its
LCD
channel.(19” for
example)

,
move cursor to item “ MODE ”, press keys “ ▲ ” and “ ▼ ” to select item “ HDMI ”, then move
cursor to item “ TEMPERTURE ”, press keys “ ▲ ” and “ ▼ ” to select item “ Standard ”
；
e) Fix item “ G GAIN ”, adjust item “ R GAIN
、
B GAIN” to set chromaticity coordinates of the 13
th
step is ( 285
、
293)
；
f) Fix item “ G OFFSET ”, adjust item “ R OFFSET
、
B OFFSET ” to set chromaticity coordinates of
the 4
th
step is ( 285 、 293 ) ；
g) During adjustment , make sure that color temperature of bright step is ( X=285±10,Y=293±15)
and color temperature of dark step is ( X=285±10,Y=293±25) ;
h) Then move cursor to item “ COPY ALL ” to copy white balance data to the other channels;
i) Check if color temperature of COOL and WARM meet requirements as below:
COOL: allowable error of bright step is ( X±5, Y±15), allowable error of dark step is ( X±8,Y±30);
WARM : allowable error of bright and dark step are both ( X±10,Y±10);
otherwise adjust items “ R_GAIN /B_GAIN/R_OFF/B_OFF ” to meet requirements and then save
data;
j)
Check if the white balance of the other channels meet the requirements, if not, adjust the data
and save separately.
