Description
Specifies if the camera automatically adjusts for a bright
background. Backlight compensation is best used in situations
where the subject appears darker than the background.
Specifies how the camera compensates for light source variations
in the room. Select Auto, Manual, or a color temperature value.
• Auto: Polycom recommends this setting for most situations. It
calculates the best white balance setting based on lighting
conditions in the room.
• Manual: Use this setting for rooms where the Auto and fixed
values don't provide acceptable color reproduction.
When you set this option to Manual, fill the camera's field of
view with a flat white object, such as a piece of paper. For best
results, the object should be uniformly illuminated with light that
is representative of the room lighting used in the conference,
rather than light from a display, another area, or a shadow.
After the object is in place, select Calibrate.
• Color Temperature Value: The color temperature values,
measured in degrees Kelvin, correspond to the color of ambient
light in a room. Because the available color temperature values
vary by camera, this list is a sampling of some of the values
you might see in the interface:
◦ 3200K (warm office fluorescent)
◦ 3680K (tungsten bulb)
◦ 4160K (cool office fluorescent)
◦ 5120K (neutral daylight)
◦ 5600K (cool daylight)
