Description
Select the terminal's video input port to which the camera is currently
connected. For example, HD IN 1, HD IN2, or HD IN 3.
This specifies use of the natural light mode. Select one of the following
modes:
l Auto: The camera automatically selects the optimum configuration
based on the environment, and Shutter delay is automatically adjusted
to prevent video quality from being affected by camera shake.
l Manual: You can manually adjust the brightness gain, shutter rate, and
aperture size.
l Iris priority: When you manually adjust the aperture, the camera selects
the corresponding shutter rate.
l Shutter priority: When you manually adjust the shutter rate, the camera
selects the corresponding aperture. This mode is mainly used to shoot
moving objects.
l Spotlight: If light reflected from a surface is too bright, select this mode
to obtain optimum video effects.
l Brightness: You can manually adjust the brightness.
This specifies the white balance to enable the camera to accurately recognize
the white color and deliver a more vivid video. The default value is Auto.
Used to enhance marginal effects, but the definition of the video is affected.
NOTE
If the aperture is changed, the definition of the video is reduced. Therefore, adjust the
aperture as required.
A greater value of this parameter contributes to less video noise but more
details that are lost. Therefore, set this parameter as required.
If this function is enabled, the terminal adjusts the camera's video output
format based on the conference video format.
For example, in the case of 720p60 conferences, the terminal automatically
sets the camera's video output format to 720p60.
Adjusts the video output level to brighten or darken the video displayed on
a monitor.
Adjusts color levels to facilitate the distinction between two colors. The
higher the contrast, the greater the degree of difference between light and
dark extremes of color.
