SECTION 3: OSD SOFTWARE SETUP
3.2 OSD Description
LENS
The LENS options include two modes: MANUAL and AUTO. In MANUAL mode, the camera uses an automatic electronic shutter.
In AUTO mode, you can set the mechanical lens to fully OPEN, fully CLOSED, or automatically controlled by the camera. SPEED sets
set the convergence speed of the mechanical iris. The lower the value, the faster the speed. If the speed is too slow or too fast, iris
control may be unstable.
SHUTTER / AGC
The SHUTTER / AGC control has two submenus: AUTO and MANUAL. In AUTO mode, the camera controls the shutter and iris based
on the BRIGHTNESS level for both HIGH LUMINANCE and LOW LUMINANCE fields of view.
•
In AUTO IRIS mode, the light level is controlled by an auto iris lens only.
•
In SHUT+AUTO IRIS mode, light level is controlled by the combination of the auto iris lens and shutter control. This mode
generally minimizes washout and produces a better dynamic range. Shutter speed can vary from 1/60 to ~ 1/10,000 sec.
In MANUAL mode, you can preset constant values for the shutter and gain (AGC) levels to constants.
WHITE BAL
WHITE BAL (balance) submenus are used to set the color temperature of the camera to match the color temperature of the field of
view. You can create two preset modes, USER1 and USER2, to use when the scene changes between two common light conditions,
or preset a constant (MANUAL) color temperature correction.
ATW (Auto Tracking White balance) limits the color temperature range at about 2,500 °K ~ 8,500 °K to reduce the excessive
compensation for big objects that have a single color.
Use the PUSH option to allow the camera to automatically set the white balance in all lighting conditions.
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.
The PUSH LOCK feature provides an alternate way to set the luminance level of the field of view. To use PUSH LOCK, point the
camera at a white paper in the field, then press ENTER. If the environment lighting changes, repeat this procedure to reset the
camera.
Backlight
•
BLC - Back light compensation. A function of the camera that compensates for excessive light directed at the camera causing
the video to bloom or causing the images in front of the light to be unusable.
•
HLC - Headlight compensation. This option blocks very bright light in the image.
