ATW FRAME Determines the ATW range with respect to the fundamental range. A
higher value than x1.00 extends the ATW range at lower and higher colour
temperature.
ENVIRONMENT Selects INDOOR or OUTDOOR . Their ATW is optimized for the
limited application.
INDOOR Optimized for indoor installation and compensates ATW for low colour
temperature such as incandescent lights.
OUTDOOR Optimized for outdoor sunlit applications and compensates ATW for
high colour temperature such as daylight.
PUSH Allows the camera automatically adjust the white balance under all conditions. 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 colour. In cases where it goes under
2,500˚K such as halogen light, ATW may stop. If so, PUSH mode is recommended.
USER1 Fluorescent light fixed gain (3200K) white balance. May be adjusted by R-GAIN and B-
GAIN and useful only for the steady light.
USER2 Outdoor fixed gain (6300K) fixed white balance, May be adjusted by R-GAIN and B-
GAIN and useful only for the steady light.
ANTI CR (Anti Colour Rolling) can reduce colour rolling under the fluorescent light when the
camera operates in shutter control without an auto iris lens.
MANUAL Allows to set B and R gain value manually.
PUSH LOCK Used to find the optimal setting for the current luminance environment. Point the
camera towards a sheet of white paper and press the SET button. Whenever the
condition changes, readjust it.
if the camera is working in an area where energy saving lamps are the only source of light the
scene might be reddish in ATW mode. In these cases PUSH mode is recommended.
5.1.4. BACKLIGHT submenu
These compensation functions allow for enhancing visibility of the objects located in the
foreground, surrounded by strongly illuminated background ( BLC ) or for enhancing visibility of the
objects located near the strong light source ( HLC ). If a strong, point light source appears on the
screen, function will mask it allowing for effective observation of the scene itself (for example this
function is used to, observe licence-plates of the cars).
5.1.5. PICT ADJUST submenu
Submenu allows to set parameters of displaying scene.
MIRROR (ON/OFF) Picture will be flipped horizontally if it is turned ON.
BRIGHTNESS (0-255) Increases or decreases the brightness of the picture.
CONTRAST (0-255) Increases or decreases the contrast of the picture.
