Picture from camera not clear
There could be any number of issues, unfortunately, your problem description doesn't give enough information, but here are some ideas.
Likely, the culprit is either a problem with focus or a problem with camera shake. In either case, brighter light and/or using a flash should help as auto focus works better in bright light and the shutter speed is faster in bright light. (With a faster shutter speed, there is less time for the camera to move while the image is recorded).
If using auto focus, be sure that the focus point illuminates on your main subject.
Many point & shoot cameras have an indicator if the shutter speed is too slow for a hand-held shot (typically occurs with low light). If this is indicated, then use a tripod (or brace your arms/elbows to make a human tripod) or increase the ISO of the camera (may have to go to manual mode) to avoid camera shake. Holding the camera at arm's length to look at the display while taking the picture is a recipe for camera shake & blurry pictures. You can rest the camera on a shelf and use the timer so that your hand motion pressing the shutter button isn't an issue. If using an SLR, ensure that the shutter speed is faster than the reciprocal of the focal length. That is, for a 100 mm lens, the shutter speed should be faster than 1/100th of a second.
