I know that people on tv and movies they always take a blurry photo and make it clear enough to see their face. I want to do this on my home pc for free
 
They actually take a clear picture and make it blurry, then show the transformation backwards. What you are describing is not possible. You cannot find detail in a photo that was not previously there without fabricating it. The photo you took can only have resolution of the camera you took it with.

I am an experienced graphic designer and I can tell you that once you blur an image it's very difficult to unblur it. The process of blurring an image is destructive, it's like burning a photograph to hide someone's face, after you burn it, it's difficult if not impossible to recover it.

Some types of blurring are similar to a two-way reversible function. By matching the function you can apply the reverse function 'restore' information. deconvolution is a often based on reverse fourier, or wavelet for the theorists.
