Defaults
If you like a particular setting for one application or light condition and
another setting for a different one, you can use the Restore and Save
buttons to save and restore these preferred settings. Should you wish
to restore all standard settings, click on the Restore button under
Factory Defaults.
6.2.4 Capture Source / Format
The fourth tab is called:'Source / Format'. It is divided into the
subsections 'Select a Source','Digital Image Format', and 'Framerate'.
Select a Source
Usually this setting has only one option when the Philips PC Camera is
the only video source connected to your computer. However, if more
than one video source is connected to your system, then this is where
you switch between them.
Digital Image Format
This setting determines the picture size of the 'live' video stream. It
also determines the size of the captured still picture.
The larger the 'live' picture size, the more data needs to be processed
by your computer. So this may have an effect on the number of
available framerates.
