Webcam tips

For optimum performance, observe the following guidelines while using the integrated webcam:
●
Be sure that you have the latest version of an instant message program before attempting a video
conversation.
●
Your integrated webcam may not work properly across some network firewalls. If you are having
trouble viewing or sending video to someone on another LAN or outside your network firewall,
contact your Internet service provider for assistance.
NOTE:
or outside your network firewall, temporarily disable the firewall, perform the task you want to
perform, and then re-enable the firewall. To permanently resolve the problem, reconfigure the
firewall as necessary, and adjust the policies and settings of other intrusion detection systems.
● Whenever possible, place bright light sources behind the webcam and out of the picture area.

Adjusting webcam properties

You can adjust webcam properties using the Properties dialog box, which is accessible from various
programs that use the integrated camera, usually from a configuration, settings, or properties menu:
● 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.
●
Gamma—Controls the contrast affecting the mid-level grays or midtones of an image. Adjusting
the gamma of an image allows you to change the brightness values of the middle range of gray
tones without dramatically altering the shadows and highlights. A lower gamma setting makes
grays look black, and makes dark colors even darker.
●
Backlight Comp—Compensates in cases where a subject with a large amount of background light
would otherwise be obscured by blooming or silhouetting.
