and an UIImage
set to it. How do I make image sharp or blur using coregraphics?

Apple has a great sample program called GLImageProcessing that includes a very fast blur/sharpen effect using OpenGL ES 1.1 (meaning it works on all iPhones, not just the 3gs.)
If you're not fairly experienced with OpenGL, the code may make your head hurt.
