That image was blurry from the get go, not a problem with Corel. You have three options: 1) Go with the macro setting mentioned by Frank and get up close, 2) Stand a few feet away and use the telephoto option to zoom in, or 3) Stand a few feet away, snap the pic at high resolution, and crop it after the fact.
Make sure your lens is clean from fingerprints (the most common cause of my SO's images coming out looking like they were taken through a jar of Vaseline... she just can't seem to keep her fingers off of the lens!).
