Philips LTC 0809 Series AutoDome Installationshinweise Seite 8

Push Button White Balance: Follow the steps below to perform
a "push button" white balance:
1. Turn auto white balance ON if it is not already.
2. Aim the camera at a white object, such as a white wall or a
piece of paper. The white object should fill the entire field-
of-view of the camera.
3. Issue the command (AUX 30 - OFF.). Automatic white
balance is now disabled and the white balance is in a fixed
position.
Fixed 3200 K White Balance On: Issuing this command
disables the automatic mode, and sets the white balance to
approximately 3200K. (AUX 35 - ON.)
Fixed 5500 K White Balance On: Issuing this command
disables the automatic mode, and sets the white balance to
approximately 5500K. (AUX 35 - OFF.)
COLOR ADJUSTMENTS (AUX 31, 32, 33, 34)
For most applications it is not necessary to make any hue
adjustments to the camera. If you do need to make hue
adjustments, be aware that by improving the color rendition of
one hue, you are probably degrading the color rendition of
some other hue. Depending on the tradeoffs required by each
applications, this may or may not be acceptable.
R-Y Saturation Increase: AUX 31 - On.
R-Y Saturation Decrease: AUX 31 - Off.
B-Y Saturation Increase: AUX 32 - On.
B-Y Saturation Decrease: AUX 32 - Off.
R-Y Hue Increase: Issuing this command will shift red hues
toward magenta. (AUX 33 - On.)
R-Y Hue Decrease: Issuing this command will shift red hues
toward yellow. (AUX 33 - Off.)
B-Y Hue Increase: Issuing this command will shift red hues
toward cyan (AUX 34 - On.)
B-Y Hue Decrease: Issuing this command will shift red hues
toward magenta. (AUX 34 - Off.)
FACTORY DEFAULT (AUX 40)
The camera can always be returned to its original state, as
shipped from the factory. (AUX 40 - On.)
Factory Defaults: Issuing this command will reset the camera
hues to their factory adjusted values, turn on the AGC and the
auto white balance, turn off the electronic shutter and the
backlight compensation, and put the camera in line-lock mode
with a phase delay of zero degrees.
ADJUST PHASE VERTICAL LINE LOCK (AUX 41)
In multicamera systems using vertical interval switchers, it is
desirable to have the video output signals from all cameras
vertically synchronized. To achieve synchronization, it may be
necessary to generate phase delays in some cameras, especially if
the cameras receive power from different phases of a 3-phase
power source. As shipped from the factory, camera vertical sync
is aligned with the positive-going zero crossing of the hot side of
the AC power input to the dome. This is the "zero phase delay"
position. The phase delay between the AC line zero crossing and
camera vertical sync can range to 360 degrees, with respect to
the original "zero phase" position. The 360 degree range is
divided into approximately 2 degree steps.
Increase Phase Delay: Issuing this command increases the line-
lock phase delay by one step. (AUX 41 - On.)
Decrease Phase Delay: Issuing this command decreases the line-
lock phase delay by one step. The phase delay commands have
no effect when the camera is in the internal crystal sync mode.
(AUX 41 - Off.)
SYNC MODE SELECTION (AUX 42)
Line-Lock Mode On: Issuing this command puts the camera
into the line-lock sync mode. The phase delay will be at the
most recently set position. (AUX 42 - On.)
Internal Crystal Mode On: Issuing this command puts the
camera into the internal crystal sync mode. In this mode, the
camera's vertical sync has no fixed relationship to the AC power
line. The vertical rate is 59.94 Hz for NTSC cameras and
50 Hz for PAL cameras. (In line-lock mode, the vertical rate is
60 Hz for NTSC cameras and 50 Hz for PAL cameras.) (AUX
42 - Off.)
AGC MODE SELECTION (AUX 43)
The camera includes an AGC circuit that automatically
increases camera sensitivity at low levels of illumination.
AGC On: Issuing this command turns the camera AGC on.
The AGC operates with its maximum range of 30 dB. (AUX 43
- On.)
AGC Off: Issuing this command turns the camera AGC off.
The AGC operates with a fixed gain of 5 dB, resulting in a loss
of camera sensitivity, but improving the signal-to-noise ratio.
(AUX 43 - Off.)
FIELD OF VIEW OPTIMIZE (AUX45)
When On, tilt is automatically adjusted during the zoom
operation such that viewing of the area above the back box
mounting plane is minimized.
AUTO-PLAYBACK (AUX 50, 51,100, 101, 500)
