SETTINGS WHICH CAN BE CHANGED IN THE CAMERA MENU of VZ-45b:
GAIN
1. Exposure Setup menu (VZ-45b only):
SHUTTER
You can change between following settings:
AUTO
OFF
STEP
VARIABLE
By changing the gain (from 0 to 18dB in 1dB steps) you can additionally amplify the video-output of the camera. This brings great
advantages under low light conditions, but also increases noise in the picture. The default mode is AUTO. In this mode the VZ-45b
automatically adjusts the Gain depending on the Iris-position and the picture-brightness. When you look very closely at the picture
you can see sometimes that the picture brightness jumps when the gain-value is automatically changed. This is normally no problem.
However, if it is disturbing, you should switch Gain manually to 0dB (or a higher value, if you do not use the built in light). If you use
x-rays or other very dark objects, you might set the Gain to 12dB or even higher manually.
This is the default mode. The shutter speed is set to 1/50. If the iris can't close anymore and the picture is still to bright
the shutter speed is changed (instead of dimming the light)
The shutter speed is set to 1/50
In this setting you can manually change the shutter speed from 1/50 down to FL, 1/125, 1/250, 1/500, 1/1000, 1/2000,
1/4000 and 1/10000 or up to 0.1sec, 0.2sec, 0.3sec and 0.5sec. When you set the shutter speed to FL (flickerless) the
flickering due to fluorescent light, etc. is reduced. Shutter speeds from 1/125 to 1/10000 might be useful when filming
fast moving objects. When changing the shutter speed to 0.1sec or higher, the Visualizer is in the long exposure mode.
In this mode you can get very good pictures under bad lightning conditions. The disadvantage is a slower picture update
rate. You also should use manual-iris in this mode as the autoiris can not work very good in this mode.
This mode is similar to the STEP, but you can adjust the shutter speed in much smaller steps. You can change the
shutter speed in 1H steps (1H equals 64s). This mode is also called clear scan mode which is useful for scanning
computer- or videomonitors without horizontal stripe noise. In the long exposure mode you can adjust the shutter
speed in frames (1/50 second).
2. General Setup menu (of VZ-45b):
3. System Setup menu (of VZ-45b):
C.TEMP (COLOR TEMPERATURE)
WHT. BAL (WHITE BALANCE)
Selects the color temperature according to the lightning
AUTO Color temperature is selected automatically when White Balance is set to AWB.
3200K Use for indoor shooting.
5600K Use for outdoor shooting.
Following settings are possible:
AWB This is the default setting. An automatic white balance is performed when the WHITE-key is pressed.
With the paint-settings you can make fine adjustments for the picture-color.
ATW The camera continuously tracks the white balance. With the paint-settings you can make fine adjustments for the
picture-color.
MANU In this mode the white balance can be made manually by changing the R/B gain-settings.
M.PEDESTAL
GAMMA
DETAIL
SYNC ON GREEN
SYNC
PAGE 3 PROTECT
With this setting you can change the video-level of dark picture-components. Normally no change is necessary. Use the brightness-
function of your display-device instead. The default setting is 0.
With this setting you can switch the gamma-compensation of the camera on and off. The default setting is ON.
Higher values make the picture look sharper, lower values result in a softer picture. The default setting is 14 which is optimized
for text-display.
With this setting sync-on-green can be switched on or off. To allow a changing of this setting, Page 3 Protect must be OFF (to
prevent accidental changes). When sync-on-green is ON the sync information is added to the green-signal of the outputs. If the
display device does not understand sync-on-green, often a green picture is displayed. The default setting is OFF.
You can change between HD/VD (default) and CSYNC. When using HD/VD the vertical sync pulse is output on the VD connector/
pin and on the HD connector/pin the horizontal sync information is available. This mode is supported by most multiscan-monitors
and projectors. In the CSYNC-mode the common horizontal and vertical sync information is output on the S/HD-connector/pin.
This mode is often used in the video-industry.
The default setting is ON. This prevents Sync on Green and Sync-Mode to be changed accidentally. To change Sync on Green or
Sync you have to switch Page 3 Protect to OFF.
