Digital camera as Webcam

Typically, Ekiga, the voice over IP / video conference application will 
also help you detect if your camera is useable in Linux.

Most often, what happens is that your camera needs to be visible in 
either Video 4 Linux (V4L) or Video 4 Linux 2 (V4L2)...

In recent distros, modern webcams supporting the USB-VC (USB Video 
Class) interface are supported by default. This thanks to the work of 
the likes of Sun 
Logitech ( and of course the authors of V4L2.

Other webcams, well it depends on the chipset on board. Webcams with 
Philips chipsets (including Logitech webcams) will work. Cams with 
proprietary chipsets (including very old Logitech webcams) likely won't, 
in most cases.
