Philips PCVC740K99 - Manual (Page 10)

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 lighting conditions.
Frame rate
The frame rate setting determines the number of images per second in the video stream.
The frame rate setting cannot be changed while Full Auto is on, as it provides automatic frame
rate adaption. You will need to switch off Full Auto to change the frame rate manually.
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). Please see Technical
Specifications for the maximum frame rates for your type of camera. 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 level of illumination (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 on the other tab is enabled.
