4.4 WHITE BAL
(White Balance)
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) are continuously monitoring/analyzing the
color temperature of the incoming light and correcting the white balance.
ATW limits the color temperature range at about 2,50 Û.a 500 Û. to reduce the excessive
compensation for the big object which has a single color.
PUSH has no limits between about 1,800 Û K~10,500 Û K but it may over-compensate the white balance for
the big object which has a single color.
In cases where it goes
under 2,500 Û. such as halogen light, ATW may stop . 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 the steady light.
ANTI CR (Anti Color Rolling) can reduce color rolling under the fluorescent light when the camera
operates in shutter control without an auto iris lens . (NTSC version only)
In cases if Switch on the camera in an area where SAVE ENERGY LAMPS are
the only source of lights the Picture might be RED in ATW mode.
In these cases PUSH mode is recommended.
ATW Default Descriptions
SPEED 250
Sets the AWB compensating speed. Lower value makes AWB faster.
CAUTION Too fast an AWB may force color oscillation.
DELAY CNT 001
Adjusts the AWB compensation period to next update of AWB.
The smaller value will update AWB more frequently (faster).
ATW FRAME X2.00
Determines the ATW range with respect to the fundamental range.
A higher value than x1.00 extends the ATW range at lower and higher color
temperature.
ENVIRON-
MENT
INDOOR
Selects INDOOR or OUTDOOR.
Their ATW is optimized for the limited application and cannot cover.
INDOOR - Optimized for Indoor installation and compensates ATW for low
color temperature such as incandescent lights.
OUTDOOR - Optimized for outdoor sunlit applications and compensates
ATW for high color temperature such as daylight.
MANUAL WB Default Descriptions
LEVEL 064 Manual White Balance Adjustment value.
