6.7 WHITE BAL menu

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.

PUSH LOCK is a fixed white balance where the white balance is compensated only while ● button is

pressed at MAIN>WHITE BAL>PUSH LOCK and finishes the white balance when ● button is released.

To enter ATW (MANUAL) menu, press ● button at MAIN menu-1>WHITE BAL>ATW(MANUAL).

ATW

Default

Descriptions

SPEED

250

Sets the AWB compensating speed. Lower value makes AWB faster.

CAUTION If AWB is too fast, it may produce color oscillation.

DELAY CNT

001

Adjusts the AWB compensation period to next update of AWB.

The smaller value will update AWB more frequently.

ATW FRAME

X2.00

Determines the ATW range with respect to the fundamental range.

A higher value than x1.00 will extend the ATW range at lower and higher

color temperature.

ENVIRON-

MENT

INDOOR

Selects INDOOR or OUTDOOR.

The ATW is optimized for limited applications.

INDOOR - Optimized for Indoor installation and it 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.
