| In addition to handheld digital cameras and camcorders, you can also capture digital images by using hardware connected to your computer. The devices used for this are computer-based cameras, which can capture both still pictures and motion video, and flatbed scanners, which can capture still pictures from existing images (such as pictures taken with an analog camera). You can jump to the information on flatbed scanners by clicking on Next.
Computer-based digital cameras are specialized digital cameras designed to capture either still or motion video while connected to a computer. They use standard computer connections.
| Compared to other digital video |
- Digital cameras and camcorders:
Computer-based cameras must be connected to the computer, which limits their range to the length of the connecting cord.
- Resolution:
Computer-based cameras usually have significantly lower resolution than digital cameras and camcorders.
- Cost:
Due in part to the lower resolution and limited range, computer-based cameras are generally less expensive than hand-held digital cameras and camcorders. |
| Convenience |
- Quick access:
Constant connection to the computer eliminates the need to connect or disconnect cables before use.
Computer-based cameras can be used to take quick, low-resolution pictures while at the computer.
- Web-based Video (with Internet acess and appropriate software):
Computer-based cameras can typically be set up for video conferencing and for use as webcams. |
