Camera Settings (CAMERA)11Sets lens aperture according to the luminance level of the targetobject.The following methods are available for setting lens aperture.• Auto iris (AUTO) • Manual iris (MANU)b Auto iris (AUTO)Automatic setting of lens aperture provides natural images evenoutdoors where the luminance difference is large, or in backlightconditions.1 Use the joystick lever (xy) to select [IRIS], use thelever (vw) to select “AUTO”, and press the [ENTER]button.The IRIS SETTING screen appears.2 Use the joystick lever (xy) to select [SENSE UP]and use the lever (vw) to select magnificationpower of electronic sensitivity.Available settings: OFF, X2, X4, X8, X16, X323 Use the joystick lever (xy) to select [LEVEL] anduse the lever (vw) to adjust the iris level.Available settings: 0 (dark) - 100 (bright)☞ After completing setting, use the lever to move the cursor to[MENU] and select “BACK” or “END”.b Manual iris (MANU)When the [IRIS] is set to “MANU”, lens aperture can be set manually.Because activating the electronic iris disables the auto iris function,you need to set appropriate lens aperture using the followingprocedure.1 Use the joystick lever (xy) to select [IRIS], use thelever (vw) to select “MANU”, and press the [ENTER]button.The IRIS SETTING screen appears.2 Use the joystick lever (xy) to select [EI] and use thelever (vw) to select “ON”.The electronic iris function controls both the AGC circuit andshutter speed to change exposure value.3 Use the joystick lever (xy) to select [IRIS STOP]and use the lever (vw) to adjust the apertureopening value.Selecting the value changes the lens aperture opening.Available settings: 1 (close, darker) - 17 (open, brighter)4 Use the joystick lever (xy) to select [LEVEL] anduse the lever (vw) to adjust the iris level.Available settings: 0 (video level is darker) - 100 (video levelis brighter)☞ After completing setting, use the lever to move the cursor to[MENU] and select “BACK” or “END”.B Setting lens aperture (IRIS)• Electronic sensitivity boosting (SENSE UP)automatically lengthens the CCD exposure time indark situations. Accordingly, moving target objectsmay cause conspicuous afterimages, blurs and whitespots.• When electronic sensitivity boosting (SENSE UP) isenabled, the electronic shutter function will not work.• When the Day/Night function is set to “AUTO”,electronic sensitivity boosting (SENSE UP) worksonly while black and white image is displayed.yyyyySYNCIRISWHITE BALANCEBLCSHUTTERAPERTUREAGCGAMMADAY/NIGHTPRESETMENUINTAUTOATWOFFOFFONON0.45AUTOOFFBACKSENSE UPIRIS SETTING[LEVEL]40PRESETMENU+OFFOFFBACKNotes on setting electronic iris (EI):• If the iris views an unusually bright image, it cancause a smear that cannot be corrected by adjustingthe light entering through the lens. In this case,arrange the physical angle of lighting in a way that willprevent on-screen smearing.• If there is a fluorescent lighting in the cameralocation, flickering of the target object may occur.Changing fluorescent lighting to incandescentlighting will prevent the flickering.• When the electronic iris (EI) is activated, theelectronic shutter (SHUTTER) setting cannot be made.EI17IRIS SETTING[IRIS STOP][LEVEL]40PRESETMENU++OFFOFFBACK
