Not at all. If the content is not sharp, the fact that it is represented 
with a lot of pixels does not imply that the sharpness is there.

If you print a blurred image at 4000 dpi, it does not improve. So, if the
lens has "printed" a not-so-sharp image on your camera sensor, in general
you cannot recover a hypothetical sharpness that is there, but is hidden. (You can recreate some sharpness, which is what the commands
"Filters->Enhance->Sharpen" and "Filters->Enhance->Unsharp mask" do.)

Unfortunately it seems that the link you provided does not work,
so I don't know exactly what you need, since I can't see your image.
