External Video Devices
Connecting an S-Video Device 
(Select

Connect the stereo end of the audio cable into an audio-out 
(headphone) jack on the computer. Connect the other end of the 
cable into the audio-in jack on the external device. For more 
information about the computer audio-out jacks and about the 
types of devices that can be connected to them, refer to the 
“
Using the Audio-Out (Headphone) Jacks” section earlier in this 
chapter.

Adjusting Camera Properties
You can adjust the following properties for the HP Webcam.
■Brightness—Controls the amount of light that is incorporated 
into the image. A higher brightness setting creates a brighter 
image; a lower brightness setting creates a darker image.
■Contrast—Controls the difference between lighter and darker 
areas on the image. A higher contrast setting intensifies the 
image; a lower contrast setting maintains more of the original 
information’s dynamic range but leads to a flatter image. 
■Hue—Controls the aspect of color that distinguishes it from 
another color (what makes a color red, green, or blue). Hue 
is
 distinct from saturation, which measures the intensity of 
the hue. 
■Saturation—Controls the strength of color in the final image. 
A higher saturation setting creates a bolder image; a lower 
saturation setting creates a more subtle image.
■Sharpness—Controls the definition of edges in an image. A 
higher sharpness setting creates a more defined image; a 
lower sharpness setting creates a softer image.

Hardware and Software Guide 4–13
■Gamma—Controls the contrast affecting the mid-level grays 
or midtones of an image. Adjusting the gamma of an image 
allows you to change brightness values of the middle range of 
gray tones without dramatically altering the shadows and 
highlights. A lower Gamma setting makes greys look black, 
and makes dark colors even darker.
■White Balance—Controls the color temperature of the 
dominant light sources. This enables white objects in the 
image to appear truly white. The white balance settings in 
the
 Properties dialog box are displayed as WB (Red) and 
WB
 (Blue). A higher white balance setting increases the 
concentration of the color (red or blue); a lower white balance 
setting decreases the concentration of the selected color.
■Exposure—Controls the relative amount of light that enters 
the camera sensor. A higher exposure setting allows more 
light; a lower exposure setting allows less light.
■Gain—Controls the intensity range, thus altering the color 
contrast of the image. A higher gain setting stretches the 
intensity range; a lower gain setting shrinks the intensity.
■Light Source—Controls the settings to adjust the camera 
exposure for the ambient light.
■Flip—Reverses the captured image vertically.
■Mirror—Reverses the captured image horizontally.
■Privacy—Turns off the capture function.
■Low Light—Lowers the frame rate automatically in a poor 
lighting environment to maintain the brightness of the 
captured image.
The Properties dialog box is accessible from various programs 
that use the HP Webcam, usually from a configuration, settings, 
or properties menu.
