How?

There are a few reasons photos aren't clear. One reason is the image is out of focus. Sometimes the autofocus will focus on the background instead of on your subject. Sometimes the autofocus will have trouble focusing in low light. If you're really having a hard time focusing, use manual focus if your camera allows it. Another reason is camera shake blur. Getting a camera with image stability capabilities can help reduce camera shake. Some other ways to help reduce the blur caused by camera shake is to use a flash. Using a tripod will also get rid of camera shake blur. Additionally, using a higher ISO speed will reduce camera shake blur. However, the higher ISO speed you use, the more noise and grain will appear in your images. There is a program called Focus Magic that can fix blurry photos. You can learn more at their website: http://www.focusmagic.com/ The program is available by itself, or as a plug-in for Photoshop. You can download a free trial version at their website. It will allow you to fix 10 photos for free, then you need to buy the program.

i don't think there is any good software that can do what you said. usually the image input will be very important to any image editing software, so if the image is blurry to begin with, there are limited things that the software can do to make it sharper. next time you snap a photo, hold the camera with both hands, take a deep breath with your finger on the shutter release, and exhale slowly...press the shutter when you're exhaling. it's been proven that that is one of the most calmest times for your conscious/sub-conscious, and your photos will be more sharper. hope it helps :)
