Tage billede med indb. webcam på Pavilion dv9000
Hvordan tager man et foto med det indbyggede webcam i en Pavilion dv9000?
Webcam'et virker fint som kamera i MSN og lignende, men vi vil gerne kunne tage et stillbillede. Dette er lykkedes før, men brugeren (kvinde) kan ikke huske, hvilket program, der blev brugt.
Using the integrated camera (select models only)
Select computer models include an integrated camera, located on the top of the display. This camera
can be used with a variety of software to
● Capture video.
● Stream video with instant message software.
● Take still photos.
The camera light (1) is turned on when the camera (2) is being accessed by a program.

Capturing and streaming video
To illustrate how each camera feature works, the following examples use specific software not available
on all computers. Select Start > All Programs to locate the video software installed on your computer,
and refer to the individual program's online Help for further information.
Capturing video
You can use the camera to capture video for playback at a later time. This example uses MovieMaker
software, not available on all computers.
1. Select Start > Programs > Windows MovieMaker.
2. Click Capture from Video Device. The Video Capture Wizard opens.
3. Click the listing for the integrated camera from the list of available devices.
4. Check the microphone and camera settings, and adjust if necessary.
5. Click Next.
6. Select the file name and path where you want to save the video file, and then click Next.
7. Select the video settings, and then click Next.
8. Click Start Capture. When you finish recording, click Stop Capture.
9. Click Finish to save the video file and close the wizard.
Streaming video with an instant message program
You can use the camera to send real-time video through an instant message program. This example
uses Windows Messenger, not available on all computers.
1. Open Windows Messenger by double-clicking the icon in the notification area, at the far right of the
taskbar.
2. Sign in to Windows Messenger.
3. Select Actions > Voice/Video > Start a Video Conversation.
4. Click the name of the person you want to connect with, and then click OK. An instant message
window is displayed, and the camera image is displayed next to the message area.
5. If the Audio and Video Tuning Wizard opens, follow the instructions to adjust your camera and
microphone settings.

Taking still photos
You can also use the integrated camera to take still photos.
1. Select Start > Control Panel > Scanners and Cameras.
2. Double-click the listing for the integrated camera, and then click Next.
3. Click Take Picture.
4. Follow the directions in the Picture Wizard to select any of the following options:
● Publish the pictures to a Web site.
● Order prints of the pictures.
● Save the pictures on your computer.
Adjusting camera properties
You can adjust the following properties for the integrated camera:
● Brightness—Controls the amount of light that is incorporated into the image.
● Contrast—Controls the difference between lighter and darker areas on the 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. 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.
● Gain—Controls the intensity range, thus altering the color contrast of the image.
● 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.
