Unshake attempts to correct shots that have a little bit of camera shake or motion blur. It has some automatic features and is worth a try.
Deblurring is different then sharpening and really is not possible to do accurately. This program may help some of your snapshots where camera shake and shutter lag are a problem on point-and-shoot cameras.
