Use my digital camera as a webcam?

Check the manual of your digital camera to see if it can be used as a webcam. Some digital cameras have this function and include software for this purpose. You'll need a USB connection from the camera to the computer unless your video card ( graphics card ), has a connection like a TV would have. If your digital camera can perform this function, plug your digital camera's power adapter into the camera. This helps on battery usage. Connect a video cable into your digital camera's video "out" port. Your camera likely came with a cable made for connecting it to a video source. Plug the other end of the video cable into your video card's (graphic card ), video "in" port on your computer. Place the camera where it will focus on you. you may need to use a microphone if your digital camera doesn't transmit sound when used as a webcam. You may also have a microphone plug in the video card ( graphic card ), for a microphone on the computer. Bottom line is...your camera instruction should tell you if this is possible at all, and how to proceed.

I'm not sure about that model. I do happen to know many digital cameras come standard with the digital webcam feature. Usually the case it comes with will tell you if it can do that or not. If not, you can always but a cheap digital camera for around $15-$20, But what you pay for is what you get.
