6.6 PICT ADJUST menu
To enter PICT ADJUST menu, press button at MAIN menu-1 >PICT ADJUST.
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) are continuously monitoring/analyzing the color
temperature of the incoming light and correcting the white balance.
ATW limits the color temperature range at about 2,500˚K~8,500˚K to reduce the excessive compensation
for the big object which 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
the big object which has a single color.
In cases where it goes under
2,500˚K 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)
PICT ADJUST Default Descriptions

will decrease.
CONTRAST 120 Increases or decreases the contrast of the picture.
SHARPNESS 128
Increases or decreases the sharpness of the picture.
Too much sharpness can make the image too harsh and show more noise
as well as line flicker at the edge of object in the picture.
