Webcam
NOTE: This section describes features that are common to most models. Some features may not be
available on your computer.
Your computer includes an integrated webcam, located at the top of the display. With the preinstalled
software, you can use the webcam to take a photo, record a video, or make an audio recording. You
can preview the photo, video recording, or audio recording, and save it on your computer hard drive.
To access the webcam and HP Webcam software, select Start > All Programs > HP > HP Webcam.
The webcam software enables you to experiment with the following features:
● Capture video.
● Record and play back audio.
● Stream video with instant message software.
● Take still photos.
● Use HP Business Card Reader to transform business cards into a usable database of contact
information.
For optimum performance, observe the following guidelines while using the webcam:
● Be sure that you have the latest version of an instant message program before starting a video
conversation.
● The webcam may not work properly across some network firewalls.
NOTE: If you are having trouble viewing or sending multimedia files to someone on another LAN
or outside your network firewall, temporarily disable the firewall, perform the task you want to
perform, and then reenable the firewall. To permanently resolve the problem, reconfigure the
firewall as necessary, and adjust the policies and settings of other intrusion detection systems. For
additional information, contact your network administrator or IT department.
● Whenever possible, place bright light sources behind the webcam and out of the picture area.
Adjusting webcam properties
You can adjust the following webcam properties:
● 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.
