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 colour
temperature of the incoming light and correcting the white balance.
ATW limits the colour temperature range at about 2,500K~8,500K to reduce the excessive compensation for the big
object which has a single colour.
PUSH has no limits between about 1,800K~10,500K but it may over-compensate the white balance for the big object
which has a single colour.
In a certain case under 2,500K 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
the steady light.
ANTI CR (Anti Color Rolling) can reduce colour rolling under the fluorescent light when the camera operates in
shutter control without an auto iris lens. (NTSC version only)
MANUAL white balance is a kind of fixed white balance which is user-programmable by B-GAIN (R-GAIN will be
automatically adjusted in accordance with B-GAIN) and useful only for the steady light.
PUSH LOCK is a fixed white balance which 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: Too fast AWB may make the colour 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.
Higher value than x1.00 extends the ATW range at lower and higher colour
temperature.
ENVIRONMENT INDOOR
Selects INDOOR or OUTDOOR.
Their ATW is optimized for the limited application and can not cover
INDOOR: Optimized for Indoor installation and more easily compensates
ATW for low colour temperature such as incandescent lights
OUTDOOR: Optimized for outdoor sunlit applications and more easily
compensates ATW for high colour temperature such as daylight.
