An IS Camera is an (I)mage (S)tabilized camera. Image stabilization (IS) is a family of techniques used to reduce blurring associated with the motion of a camera during exposure.
With still cameras, camera shake is particularly problematic at slow shutter speeds or with long focal length (telephoto) lenses.
I use a Canon Powershot. The powershot model number SX130IS indicated the Canon Powershot Image Stabilized mode.
I really enjoyed using this IS Camera. Though in the Super Vivid mode, it can be difficult to get a sharp shot in low light. Still it IS a very popular camera, and I can fully recomend Canon Powershot SX130IS if you are looking for an IS Camera.

Examples of Tilt-Shift Video
Here are two examples of simulated miniature, or "Tilt-Shift" video, created with the Canon Powershot SX130IS.
Here is a good Wikipedia explanation of "Tilt-Shift" photography.
"Selective focus via tilt is often used to simulate a miniature scene, though as noted above, the effect is somewhat different from the shallow DoF in close-up photography of miniature subjects. Many such images are described as employing "tilt-shift", but the term is something of a misnomer because shift is seldom involved and is usually unrelated to the effect produced. The term may derive from the tilt-shift lens normally required when the effect is produced optically.
Basic digital postprocessing techniques can give results similar to those achieved with tilt, and afford greater flexibility, such as choosing the region that is sharp and the amount of blur for the unsharp regions. Moreover, these choices can be made after the photograph is taken."
