Control: Full Auto on/off 
This Full Auto mode provides a very easy way to get the best out of your camera. Or you can 
choose to have maximum manual control over the camera settings by switching the Full Auto 
mode off. Full Auto 'on' is the preferred setting for normal use. 
Functions activated in Full Auto mode are: 
- Automatic exposure control and automatic white balance control, to provide the best video 
source signal possible. 
- Dynamic Noise Reduction (DNR) and automatic frame rate selection for improved camera 
sensitivity in low light conditions. 
 
Frame rate 
The frame rate setting determines the number of images per second in the video stream. 
 
The set of frame rates from which the user can choose depends on the currently selected video 
format (resolution) and the available bandwidth on the USB bus (the number of devices 
connected to your USB port and the amount of data they transport). The buttons for invalid frame 
rates will be greyed out automatically and cannot be selected. To enable higher frame rates 
choose a smaller video image format in your application. Applications will usually offer resolution 
switching (image format setting) under menu items within the applications themselves. 
 
Image Controls 
Here you will find the slider controls for brightness, contrast, gamma correction and saturation. 
Note that the contrast control is only available when the Auto Exposure setting is enabled on the 
other tab (marked Camera controls). 
 
Modes 
The checkbox 'Black and white' is used to switch from colour images to black & white and back. 
 
By clicking the checkbox 'Mirror Image', the image flips horizontally. This feature can be applied 
in order to use the camera and monitor as a mirror, or for taking pictures of mirrored images. 
 
Turn on the backlight compensation to improve the image quality when you have a scene 
where the background has a high illumination level (for instance when you are sitting in front of a 
bright light). Note that the backlight compensation option is only available when the Auto 
Exposure setting is enabled on the other tab.
