4 Using the applications
This section gives a brief description of how to use the video software packages included
on the CD-ROM. If you have not yet installed these applications, please read 'Camera and
software installation' for installation instructions.
4.1 General
VLounge is the central application for easy access to your Philips USB PC Camera and the video
applications installed during setup, together with access to one application of your choice. You
can start VLounge using the Windows QuickLaunch menu on the taskbar, through the program
group 'Philips ToUcam Camera', or by double-clicking the VLounge icon
on the desktop.
The buttons to the right in the VLounge windows will start the applications. If you did not install all
the applications, some of these buttons will be greyed out and will not activate when the cursor
moves over them, indicating that the application is not available. Please re-run the Philips 'Setup'
installation program from the CD-ROM to install any missing applications.
The other buttons and the menus offer access to other useful camera options.
Where to get help on the applications
For detailed information about the use of the software packages, please read the accompanying
information for the relevant software. Each software package usually creates its own program
group in the Windows Start menu, which is activated by clicking on the Windows Start button.
These program groups contain the application program icon and other items (Help files,
Electronic Manuals, Uninstall Wizards, Readme files, etc.) for the specific software package. All
available information is accessible via the software's program group, or through the Help options
within the program.
5 Settings
The camera properties (audio and video) can be changed from within an application, or
independently by clicking the VProperty icon
which can be found in the right hand part of the
Windows taskbar at the bottom of your screen. Most applications can show a 'live preview' video
image on your monitor. Always use this option to see the effect of changed settings on your
screen. NOTE: Windows®XP may hide inactive icons. Hidden icons can be displayed by clicking
the Unhide button on the taskbar.
5.1 Image Controls
The first property tab is marked 'Image Controls'.
This text box is used to inform the user about camera settings, problems or special
circumstances. Important messages will show a flashing icon. The same icon also appears in the
'Camera controls' tab to indicate that an important message is displayed in the Performance text
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).
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.
5.2 Camera Controls
The next tab is marked 'Camera Controls'.
White Balance
In Auto mode the camera automatically controls the different colour components in the picture to
obtain the most natural colour reproduction. This setting is the preferred setting for normal use.
The white balance settings cannot be changed without first switching off Full Auto in the 'Image
controls' tab.
Switch off the automatic white balance control to enable Manual control. The current colour
setting will remain frozen and will not be influenced by the camera's internal controls. Put the
white balance setting in Manual mode when you have a colourful scene and stable lighting
Indoor / FL / Outdoor: These settings compensate for the specific colour spectrum of these types
of lighting. However, these compensations are fixed, so under changing lighting conditions it is
better to use the Auto setting. Use the 'Red' and 'Blue' sliders to control the white balance
manually referencing to a fixed green setting.
The exposure setting determines the amount of light that will fall onto the video sensor chip by
controlling the gain and shutter speed.
In Auto exposure mode the camera automatically adjusts the gain and shutter speed.
The exposure settings cannot be changed without first switching off Full Auto in the 'Image
controls' tab.
In manual mode (no check mark in the Auto checkbox) you can control the gain and shutter
speed settings manually. The manual exposure mode disables the controls for contrast and
backlight compensation in the other property tab (marked Image Controls) and the flickerless
control in this tab.
If you like a particular setting for particular lighting conditions, you can use the Save and Restore
buttons to save and restore this preferred setting. Should you wish to restore all standard
settings, then click on the Restore button under Factory. The default values apply to both the
'Image controls' tab and the 'Camera controls' tab.
Performance icon
The Performance text box on the 'Image Controls' tab is used to inform the user about camera
settings, problems or special circumstances. Important messages will show a flashing icon. The
same icon also appears in the 'Camera Controls' tab to indicate that an important message is
being displayed in the Performance text box on the 'Image Controls' tab.
The Flickerless option should only be used under flickering 50/60 Hz light conditions (e.g.
fluorescent or neon lamps) to prevent flickering or strangely coloured video images. If this option
is used under normal lighting conditions the video image will tend to be overexposed. Note that
the flickerless control is only available when the Auto Exposure setting is enabled on this tab.
Please indicate under Mains whether your mains power frequency is 50 Hz (Europe) or 60 Hz
(USA) so that the Flickerless control will work correctly.
5.3 Audio Controls
The third tab is marked 'Audio Controls'.
Volume slider
This slider provides manual control over the microphone volume. The 'Volume Wizard' helps you
to select the correct sound level setting for the slider control.
Balance slider
Not implemented since the camera microphone itself produces a mono audio signal.
Shuts off the microphone completely. This option will be greyed out and cannot be used if it is not
Volume Wizard (Automatic volume setting)
By pressing the 'Volume Wizard' start button, an Automatic Gain Control cycle is started for the
camera microphone to determine the optimum volume setting. Speak into the microphone until
the Volume Wizard stops or until you press Cancel.
Audio Format
Audio format shows the parameters of the audio data. You can change these parameters in your
application in the same way as the resolution setting, for example.
Performance icon
The Performance text box on the 'Image Controls' tab is used to inform the user about camera
settings, problems or special circumstances. Important messages will show a flashing icon. The
same icon also appears in the 'Audio Controls' tab to indicate that an important message is being
displayed in the Performance text box on the 'Image Controls' tab.
Set preferred recording device
Clicking this button makes the Philips ToUcam camera the preferred recording device. This
button will be disabled if the Philips ToUcam audio device is already selected as your preferred
recording device. Windows stores the user's preferred recording device in its multimedia settings.
Applications can use this setting for selecting a user-preferred audio source.
Use preferred devices only
Use this option to enforce or stop using the preferred device only. For most camera applications it
is preferable to check this option.
5.4 Capture Source
Some applications may offer you a fourth tab called 'Capture Source'. Usually this setting has
only one option when the USB PC Camera is the only video source connected to your computer.
However, if more than one video source is connected to your system, you can switch between
them here. Applications that do not show this fourth tab will offer video source switching under a
different menu item within the application itself.
NOTE: If you have two or more Philips USB cameras connected to your computer, they can only
be used one at a time.
6 TWAIN applications
Use the camera's voice control feature (say 'Cheese') to be sure to capture an image of you
smiling. The Philips USB PC Camera is TWAIN-compatible (like a scanner), so you can use the
camera as an input device for any application software that uses TWAIN as a data source (e.g.
photo editing software).
IMPORTANT NOTE: Windows®XP might start a generic WIA interface (Windows Image
Acquisition) when you choose the camera device name with the WIA prefix as your source device
for image capture, instead of the TWAIN View Finder depicted below. This Microsoft® WIA
interface allows you to capture still images with your camera, but without the advanced
capabilities of the TWAIN software described below (e.g. no voice control feature). Please select
the 'Philips ToUcam Camera' as your TWAIN source device for acquiring still images with your
6.1 Capturing images from within applications
In TWAIN-compatible applications you will see the Philips USB PC Camera listed as an available
TWAIN data source among your other TWAIN sources (e.g. scanners). Just pick the USB PC
Camera as your source, to capture camera pictures directly into your application. Then choose
'Acquire' to launch the camera viewfinder, which displays the moving video picture.
To capture a still image, say 'Cheese', click on the 'Capture' option under the viewfinder, or push
the snapshot button on top of the camera.
6.2 Capture settings
To the right of the 'Capture' button you will find the 'Adjustments...' button, which is used to
change the settings. Clicking the 'Adjustments...' button will bring up the following window.
Camera source
Usually this setting features only one option when the USB PC Camera is the only video source
connected to your computer. However, if more than one video source is connected to your
system, this is where you switch between them.
The 'Camera Controls' button will bring up the other camera setting tabs as described under
'Camera Settings'.
Image formats
Here you can select the size of the still image to be captured. To the right of the still image format
the streaming image format indicates the size of the preview window independently of the still
image format.
Single Image Capture - 'Voice Controlled' snapshot
(This option will be disabled (greyed out) when Auto Image Capturing is enabled)
The 'Voice Controlled' check box disables/enables voice controlled capturing. If this function has
been enabled the user can start capturing by saying 'Cheese' (or pushing the 'Capture' button in
the Viewfinder or pressing the camera's Snapshot button).
The countdown timer selection box sets the capture delay time between triggering the capture
(pressing the 'Capture' button, the camera Snapshot button or saying 'Cheese') and the actual
capture of a still image. During countdown, a countdown timer will be visible and the camera
indicator LED will start flashing.
Auto Image Capture
In the 'Auto Image Capture' section you can enable the Auto Capture function together
with an appropriate timer interval. This function triggers the capture of images at
adjustable, regular intervals. The 'Capture' button in the View Finder changes to an 'Auto
Start' button to indicate this selection, and the Voice Control option will become
Leave 'Incremental File Save' unchecked if you want to overwrite the previous image
when capturing a new one. If you do check this box, the picture data is saved under the
selected filename but extended with one or more digits. This digit is increased for each
new image so that the previous images will not be overwritten.
You can enter a name for the captured images at 'File Name', or browse until you find a
suitable name to use. Use 'File Type' to choose between four supported file formats:
BMP, TIF, JPG, or FlashPix. Use the Options button to define file type specific save
options for the selected file type. (Only the file types BMP and JPG have options).
Shutter sound
You can choose a sound file for the shutter sound when an image is captured. Normally
this is a clicking sound resembling the sound of a camera shutter. Uncheck the Play
Shutter Sound box to disable the shutter sound.
7 Tips and Frequently Asked Questions (FAQs)
7.1 Tips
Installing/uninstalling the camera
Always use the Philips installation CD-ROM to install the correct camera drivers, as
described below. Do not connect the camera to a USB port before installing the Philips
drivers. If you do this, Windows will try to install its own drivers, which might be less
compatible with the camera than the Philips drivers. You must have Windows running
and have the Windows CD-ROM to hand.
Your USB controller should be working correctly. You can check this in the Windows
Device Manager (Click on the My Computer icon on your desktop, right-click Properties,
then click on the Device Manager tab (for Windows®XP & 2000: Start / Control Panel /
System / Hardware / Device Manager)). An icon with the name 'Universal serial bus
controller' will now be visible. Click on this icon and Windows will tell you if this part of
your computer system is operating correctly.
Uninstall the driver software by using the Add/Remove option in the Start - Settings Control Panel - Software window (for Windows®XP & 2000: Start / Control Panel /
If the installation program asks you to place a different CD-ROM in the CD-ROM drive,
for instance the installation CD-ROM or the Windows CD-ROM, always wait until:
the 'busy' cursor icon (usually an hour-glass icon) has disappeared from your
screen, and
the 'busy' LED on your CD-ROM drive extinguishes,
before pressing the eject button on the CD-ROM drive.
This will prevent a blue Windows Error message appearing, prompting you to reinsert
the last CD-ROM into the drive.
Should you encounter this Windows Error message, correct the error by reinserting the
CD-ROM you removed and wait for Windows to finish reading from the CD-ROM.
Camera performance and system requirements
At its highest resolution, this digital USB PC Camera provides a very large data stream, which
needs to be processed in real-time by the application you are using. Although the camera will
perform satisfactorily on a Pentium II with 32 MB RAM at the lower resolutions, we recommend a
more powerful computer for optimum performance at the highest resolution. We regret that
optimum camera performance cannot be guaranteed if the computer only meets the minimum
system requirements.
Using more than one camera
If two or more Philips cameras of the same type are connected to your computer, only one of the
cameras can be used at any one time.
You can connect the camera to any USB port on your computer. The computer does not have to
be switched off. USB ports are 'hot-swappable', which means that you do not have to restart
Windows every time you connect a new USB device. The USB driver will detect the camera as
new hardware. It can be used within a few seconds, without the need to restart the computer.
If you unplug the camera while it is actively providing an audio or video stream to an application
on your computer, the computer may crash. To avoid these problems, first close any applications
using audio from the camera microphone or video from the camera before unplugging the Philips
USB PC Camera.
Driver software check
You can determine if the camera is installed
correctly, and if it is being recognized by the
operating system, by checking the Device Manager
menu in System Properties.
1. Access this menu by right-clicking 'My
Computer' in the top left-hand corner of the
desktop (for Windows®XP: in the Start
menu), and clicking Properties.
Alternatively, click on Start / Settings /
Control Panel, then double-click on System
to access the menu (for Windows®XP:
Start / Control Panel / System / Hardware).
2. Click on Device Manager to view the list of
installed devices.
If the USB PC Camera has been installed correctly
and it is plugged into a USB port, you will see the
following devices in the list (double-click on the
devices to see their specifications):
Imaging Device:
Philips ToUcam <XS, Fun or Pro> Camera; Video
Sound, video and game controllers:
Philips ToUcam <XS, Fun or Pro> Camera; Audio
Universal serial bus controller:
Philips ToUcam <XS, Fun or Pro> Camera;
Composite A/V Device
If you unplug the camera from the USB port, these
devices will disappear from the list (and can
therefore not be used by any application on your
computer until you reconnect the USB camera).
If you have any questions or experience any problems with the camera, please visit our website
at for new or updated information.
7.2 FAQs
Q: I can't control the volume of the camera audio device. There is no volume control
visible in the Volume Control recording properties.
A: Double-click the camera icon on the Windows taskbar. If there is no camera icon on the
taskbar, start VLounge and select 'Configuration - Icons', and enable 'Driver icon on taskbar', then
click the camera icon on the taskbar. NOTE: Windows®XP may hide inactive icons. Hidden icons
can be made visible by clicking the Unhide button on the taskbar. Go to the Audio tab and make
sure the microphone volume has been turned up and that the camera microphone is the preferred
recording device. See also ‘Camera Settings – Audio’.
Q: Why can't I choose higher frame rates for the USB Camera?
A: As the digital camera is a USB device, it shares the bandwidth of the USB port with all the
other USB peripherals. If these USB devices are active (speakers providing sound or scanners
performing a scan), the remaining bandwidth may be restricted to frame rates lower than those
listed in the 'Technical specifications' as the maximum frame rate for that resolution.
Q: Why does my camera have trouble functioning in combination with an optical USB
A: USB bandwidth is limited and may not be sufficient to support both an optical mouse and the
camera simultaneously. Several solutions are possible depending on your particular situation:
1. If your system is equipped with 2 or more USB host controllers, try connecting the
camera and the optical mouse to different host controllers. (Most systems will only have
one host controller.)
2. If the first solution is not possible and you have an external microphone available and
connected to your sound card, change the audio device setting to 'Sound card audio'
instead of 'USB audio' to save on USB bandwidth.
3. If the second solution does not work you can reduce the camera's USB bandwidth usage
as follows:
o Install ToUcamBW8.reg.
o Acknowledge the registry update by answering 'Yes'.
o Reboot your PC to allow the changed settings to take effect.
Q: My PC will not start when the camera is connected.
A: It is highly likely that your BIOS is not compatible with the USB standard. Contact your PC
supplier for an updated BIOS.
Q: With additional USB peripherals installed my PC seems to be unstable (blue screens).
A: Check if Phoenix Plugworks is one of your applications. You need to have version 1.1 or
higher for correct operation with Windows.
Q: No USB Device: My Windows Device Manager reports 'No USB device' even though I
have a physical USB port. In the Windows Device Manager (right click on My Computer
(for Windows®XP: in the Start menu), click on Properties, (and for Windows®XP & 2000 on
the Hardware tab), then Device Manager), no section with the name 'Universal serial bus
controller' is visible.
A: Check whether your BIOS enables the USB port as follows: reboot your computer, enter your
BIOS setup and look for a text such as 'USB function'. This should be enabled.
Q: No Video: My application doesn't display any video.
A: There are several reasons for not having video:
1. Check whether the USB PC camera is connected to a USB port
2. Check whether 'Microsoft WDM Image Capture' is the current capture source. On
systems with other devices, this other device may be the selected capture source.
3. If more than one USB capture device is connected to the PC, check whether the correct
USB capture device has been selected.
Q: (Windows 98 only!) No 'Microsoft WDM Image Capture': 'Microsoft WDM Image Capture'
is not available as image capture source.
A: All USB Image devices need 'Microsoft WDM Image Capture' as the capture source. Check
whether this capture source is enabled. (Start, Settings, Control Panel, MultiMedia, Device tab,
Video Capture Devices entry. Double-click the 'Microsoft WDM Image Capture' entry. A property
page will pop up. The option 'Use the video capture device' should be selected).
Q: Why does my application crash when I unplug the camera from the USB port?
A: If you unplug the camera while it is providing an audio or video stream to an application on
your computer, the computer may crash. To avoid problems always close applications that use
audio from the camera microphone or video from the camera before unplugging your Philips USB
PC Camera.
Q: The snapshot button on top of the camera does not function in Windows®XP.
A: For Windows®XP the snapshot button support has not yet been implemented in the TWAIN
driver software. As an alternative for taking pictures, please use the voice-controlled snapshot
option (Say 'Cheese!') or click the capture button in the preview window of the application you are
The snapshot button issue will be resolved in due course. Please check
for available updates. Selecting the camera device name with the WIA prefix will not solve this
problem, because Microsoft's WIA image acquisition protocol does not support the camera's
TWAIN functionality (such as the voice-controlled snapshot option or the snapshot button on top
of the camera).
Q: Voice-controlled snapshot option (Say 'Cheese!') does not function.
A: There are several reasons for not being able to use the voice-controlled snapshot option:
1. Incorrect audio recording settings. Solution: check your audio settings (see below in the
next FAQ).
2. Incorrect TWAIN source selected in Windows®XP. Preferably, you should select the
'Philips ToUcam Camera' as your TWAIN source device for acquiring still images with
your camera. Please do not select the camera device name with the WIA prefix, because
Microsoft's WIA image acquisition protocol does not support the camera's TWAIN
functionality (such as the voice-controlled snapshot option or the snapshot button on top
of the camera).
Q: The video works, but no audio is recorded: My application doesn't produce any audio.
A: There are several reasons for not having audio:
1. Check whether audio recording has been enabled in your application.
2. Check whether the USB PC camera microphone is selected as the current recording
device. (Start, Settings, Control Panel, MultiMedia (Sounds and Audio Devices for
Windows®XP, or Sounds and Multimedia for Windows®Me and 2000), Audio tab. In the
recording section, the 'Philips camera, Audio (Microphone)' should be selected).
3. Check camera properties. You may have muted the camera microphone. If so, enable
the camera microphone volume.
Q: No audio (USB timer outside specification)
A: If you hear no audio, and have tried every troubleshooting tip in the user guide and the on-line
help to no avail, the USB hardware in your computer may be the cause of the problem. This could
particularly be the case if you are using an older type of motherboard. In most cases, the USB
timer clock will not be stable enough for streaming audio applications.
Q: System lockup: My camera stops responding (black or frozen picture or LED off) for no
obvious reason.
A: Switch off the Hardware Accelerator for your video card (right-click with your mouse on the
Windows desktop and choose 'Properties' to open the desktop settings. Click the Settings tab,
click Advanced and click the Troubleshooting tab (click the Performance tab for Windows®Me
and 98). Set 'Hardware Acceleration' to 'None'). Contact your video display card manufacturer to
obtain the latest video card drivers. See the video display card's documentation for more
Q: Picture Flicker: My video picture is flickering.
A: This may happen in office environments with 50 or 60 Hz fluorescent lighting when certain
frame rates are used. There are two solutions:
1. Select the 'Flickerless' option. This option is located in the 'Image Controls' property
page. This property page is accessible from within the application you are using.
2. Deselect the 'Flickerless' option. The frame rates '5', '10' and '20' are always flickerless in
50 Hz lighting environments. Only the frame rates 15, 25 and 30 are affected by the
electronic 'Flickerless' control.
Q: 'Unable to draw this data format': The message 'Unable to draw this data format'
A: This can happen when the selected data stream format could not be processed due to a
missing codec. Re-install the camera driver software to install the missing codec.
Q: Why are frames dropped during the recording of a streaming video?
A: If a video clip is created at a high resolution and high frame rate, a tremendous amount of data
is generated. For example, the amount of video data generated using VGA resolution at 30 fps
with 24 bit full colour is 640x480x30x24 = 221,184,000 bits (221 Mbit) or 27.65 Mbyte per second.
Audio adds even more data on top of this. Hardly any computer system and/or hard drive is
capable of handling this kind of data stream. The result is that a number of frames are dropped in
order to match the data stream with the capabilities of your computer. This effect can be reduced
or completely eliminated by applying the following measures:
changing to a lower resolution such as 320x240 or lower
changing to a lower frame rate
putting the hard drive in DMA mode
using a new file instead of overwriting an existing one
Q: Why do I sometimes hear clicks in my audio during playback of a video clip?
A: During the recording phase the processor (CPU) has to process a lot of data and the
processing capacity will be limited by the maximum computing speed of your processor. This also
explains why the actual video result you can achieve strongly depends on the processor present
in your computer. The processor also has to control the timing for the transmission of video data
from the camera to your computer. This is done by giving the camera a command to send video
data every millisecond. If the processor load is high, commands will sometimes be missed,
resulting in gaps in the audio and video stream. With audio, this results in a 'click' sound. The
higher the processor load, the more clicks may be generated. This effect can be minimized and
even completely eliminated by reducing the processor load, for example by:
changing to a lower resolution, e.g. 320x240
changing to a lower frame rate
putting the hard drive in DMA mode
using a new file instead of overwriting an existing one
Please bear in mind that the majority of video applications do not require high resolutions in
combination with high frame rates. In most cases, therefore, you will not encounter this
phenomenon at all.

10 Glossary
Audio input device (recording device)
One of the Windows multimedia settings is the recording device setting. This setting determines
which audio hardware is being used to provide audio signals to audio applications. This setting is
accessible through: the Windows 'Start' menu, Settings, Control Panel, MultiMedia, Audio tab. In
the recording section, the USB digital camera microphone should be selected. (This selection will
only be available if the camera is connected to a USB port.)
The Microsoft standard file format for combined video and sound files on the PC. This is part of
the Video for Windows standard.
BMP / JPG / TIFF / FlashPix
These are various file formats for images. BMP files are the largest since they do not use
compression and retain full image quality. JPG uses 'lossy' compression, which dramatically
reduces file size, but the original image quality can never be restored. TIFF can use a 'lossless'
compression algorithm with less file size reduction, but retaining full image quality. FlashPix is a
relatively new image format that uses minimal resolution within the application to speed up the
image processing. All accepted changes are processed afterwards, before writing to disk.
Codec (COding & DECoding)
This refers to a compression format for creating sound and video streams on the computer.
Term used to describe a process of compacting or squeezing video and sound information into a
smaller than normal size. For example, 2 to 1 compression would indicate that 2 pixels would now
only occupy the space of 1 pixel.
The latest standard developed primarily by Microsoft to help establish a common method for
exchanging audio and video information between your hardware and software in the PC.
A single image in a video stream.
Frame Rate
Typically quoted in seconds (fps, frames per second), this refers to the number of single images
that will be displayed or captured in a video stream.
Gamma Correction
The characteristics of displays which use phosphors (such as computer monitors with cathode
ray tubes) are nonlinear. Nonlinear characteristics means that a small change in voltage, when
the voltage level is low, produces a change in the brightness level of the output display, but this
same small change in voltage at a high voltage level will not produce the same magnitude of
change in the brightness output. This effect is known as gamma. Computers like to process with
linear RGB data. Before being displayed, this linear RGB data will be processed (gamma
corrected) to compensate for the gamma of the display.
Indicator LED
The LED on top of the camera will be illuminated when it is delivering video images to your
computer, and not illuminated when it is not. It will flash before a timed snapshot is taken. One
second before the snapshot countdown ends, it will flash more rapidly to warn you of the
impending event.
Philips installation program
A standard installation program that runs from the CD-ROM. Normally, this program starts
automatically after the installation CD-ROM has been inserted into the CD-ROM drive, and will
guide you through the whole installation process. The program can be started manually by
running 'setup.exe' from the CD-ROM drive.
The smallest square or round element in an image. These are the 'building blocks' that are only
one colour in their individual state, but combine with others to form complete images.
Plug & Play
An operating system principle for connecting hardware to your computer. The idea is to recognize
the new hardware automatically and to load the appropriate drivers without restarting your
computer. With USB devices this usually means that you will have to perform an installation
procedure only once, i.e. the first time you connect the new hardware. After the initial set-up, you
will not have to restart the computer when connecting the camera to the USB port. The USB
driver will detect the camera as newly connected hardware. It can then be used within a few
seconds without the need to restart the computer.
Preview Window
The window within the capture application that is used to display live, or moving, video.
Property page
A window with camera setting tabs that appears when you click on a setting menu item within an
application. This setting menu item can have different names in different applications, but is
usually called 'Settings', 'Preferences', 'Video settings' or similar.
Restarting your PC to initialize all original settings and finalize all settings changed during an
installation procedure.
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.
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.
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 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.
