Resolution
Typically given in the context of pixels, this is used to describe overall video size. This is related
to quality in that the higher the resolution, the better the quality and the more pixels.
Snapshot button
The hardware button on top of the camera which fulfils the same function as the software
'Capture' button in the TWAIN viewfinder window. If the viewfinder displays the camera's view on
your screen in the TWAIN viewfinder window, pressing this button will capture a still image.
TWAIN
Standard software interface for imaging applications. If a hardware device has a TWAIN driver, it
can be used as an image source for TWAIN-compatible imaging applications. Choose your
TWAIN source in the imaging application itself. Then choose 'Acquire' to start the TWAIN driver
for the TWAIN source.
USB
Universal Serial Bus, used for connecting external devices to the PC without having to restart
your PC.
Video for Windows
Developed by Microsoft, this is a standard for displaying video on the Windows desktop. Windows
has this built in. This standard has now been superseded by DirectShow, which is part of DirectX.
Video stream
A collection of images that combine to form motion - or moving - pictures (also known as movies
or video clips).
WIA
WIA is short for Windows Image Acquisition. Windows®XP might start a generic WIA interface
when you choose the camera device name with the WIA prefix as your source device for image
capture, instead of the TWAIN View Finder. This Microsoft® WIA interface allows you to capture
still images with your camera, but without the advanced capabilities of the TWAIN software.
Preferably, you should select the 'Philips ToUcam Camera' as your TWAIN source device for
acquiring still images with your camera.
