since both zones are the same. A dome operator can
see where the backlight compensation zone will average
in the field-of-view.
Electronic Shutter (AUX 22, 23)
The camera's electronic shutter covers a range of 1/60
second (1/50 second for PAL units) to 1/10,000 second
in 261 steps (311 steps for PAL units). As the electronic
shutter speed increases, the time allowed during each
video field for light to collect on the CCD decreases,
resulting in a loss of sensitivity. However, higher shutter
speeds tend to produce a "stop action" effect on moving
images, greatly increasing the camera's dynamic
resolution.
Increase Electronic Shutter Speed: Issuing this
command will turn on the electronic shutter, and
increase the shutter speed by one step. (AUX 22 - On.)
Decrease Electronic Shutter Speed: Issuing this
command will turn on the electronic shutter, and
decrease the shutter speed by one step. (AUX 22 - Off.)
Electronic Shutter Off: Issuing this command will
disable the camera's electronic shutter. (AUX 23 - Off.)
Electronic Shutter On: Issuing this command will turn
on the camera's electronic shutter. The shutter speed
will be at the last set position. (AUX 23 - On.)
White Balance (AUX 30, 31, 32, 35)
Auto White Balance On: Issuing this command turns on
the automatic white balance. The white balance setting
adjusts continuously as the color temperature of the
scene changes. This mode is recommended for
situations where the color temperature of the scene
varies during shooting. Continuous white balancing may
not produce optimum color rendition when little or no
white is present in the scene. (AUX 30 - On.)
Perform "Push Button" White Balance: Take the
following steps to perform a "push button" white
balance:
1. 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.
2. Issue the command (AUX 30 - Off.). The picture
should turn white within a few seconds. Continuous
automatic white balancing is now disabled.
Turning on the manual white balance disables the
automatic white balance. There are 107 steps of
adjustment for changing either the red or blue content of
the picture.
Manual White Balance - Increase Red: Issuing this
command increases the red content of the picture by
one step. (AUX 31 - On.)
Manual White Balance - Decrease Red: Issuing this
command decreases the red content of the picture by
one step. (AUX 31 - Off.)
Manual White Balance - Increase Blue: Issuing this
command increases the blue content of the picture by
one step. (AUX 32 - On.)
Manual White Balance - Decrease Blue: Issuing this
command decreases the blue content of the picture by
one step. (AUX 32 - Off.)
Fixed 3200 K White Balance On: Issuing this command
turns off the automatic mode, and sets the white balance
to approximately 3200 K. (AUX 35 - On.)
Fixed 5500 K White Balance On: Issuing this command
turns off the automatic mode, and sets the white balance
to approximately 5500 K. (AUX 35 - Off.)
Hue Adjustment (AUX 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
trade-offs required by each application, this may or may
not be acceptable.
R-Y Hue Increase: Issuing this command will shift red
hues toward magenta by one step. (AUX 33 - On.)
R-Y Hue Decrease: Issuing this command will shift red
hues toward yellow by one step. (AUX 33 - Off.)
B-Y Hue Increase: Issuing this command will shift blue
hues toward cyan by one step. (AUX 34 - On.)
B-Y Hue Decrease: Issuing this command will shift blue
hues toward magenta by one step. (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.
