White balance can be set to ATW, PUSH, USER1, USER2, ANTI CR, MANUAL or PUSH
LOCK.
ATW (Auto Tracking White balance) and PUSH (Full pull-in) is continuously monitoring/analyzing the
color
temperature of the incoming light and correcting the white balance.
ATW limits the color temperature range to about 2,500
˚
K~8,500
˚
K to reduce the excessive compensation
for a large object that has a single color.
PUSH has no limits between about 1,800
˚
K~10,500
˚
K, but it may over-compensate the white balance for
a large object that has a single color.
In cases under 2,500
˚
K such as halogen light, ATW may stop and if so, PUSH mode is recommended.
USER1 and USER2 are a fixed white balance which is user-programmable by R-GAIN and B-GAIN and
useful only for consistent/steady lighting.
ANTI CR (Anti Color Rolling) can reduce color rolling under fluorescent lighting when the camera
operates in shutter control mode without an auto iris lens. (NTSC version only).
MANUAL white balance is a kind of fixed white balance that is user-programmable by B-GAIN, (R-GAIN
will be automatically adjusted in accordance with B-GAIN) and useful only with consistent/steady lighting.
