White Balance
White Balance has the following modes, all of which
can be set using VISCA Commands.
• Auto White Balance
Auto white balance obtains the proper color
reproduction by automatically adjusting white
balance to ensure a white object always looks white.
This function computes the white balance value
output using color information from the entire screen.
It outputs the proper value using a pre-set value for a
color temperature radiating from a black subject
based on a rage of values from 2000 to 10000K.
This mode is the default setting.
Note
When the light source suddenly changes from the light
source available when the FCB camera was turned on, the
proper color reproduction may not be obtained because the
system cannot compensate the sudden change of color
temperature.
• ATW
Auto Tracing White balance (2000 to 10000 K)
• Indoor
3200 K Base Mode
• Outdoor
5800 K Base Mode
• One Push WB
The One Push White Balance mode is a fixed white
balance mode that may be automatically readjusted
only at the request of the user (One Push Trigger),
assuming that a white subject, in correct lighting
conditions and occupying more than
is submitted to the camera.
One Push White Balance data is lost when the power
is turned off. If the power is turned off, reset the One
Push White Balance.
• Manual WB
Manual control of R and B gain, 256 steps each
Automatic Exposure Mode
The variety of AE functions, which allow video signal
to output the optimum image for subjects from low
light conditions to bright light conditions, are
available.
