You can use this to sharpen the image, that may help deblur it. This will allow you to select an area that you want to sharpen.
I = imread('image name');
imshow(I)
BW=roipoly;
imshow(BW)
h = fspecial('unsharp');
I2 = roifilt2(h,I,BW);
imshow(I)
figure, imshow(I2)

It works a little but is not enough, what I can do to improve the sharpness?
Thanks!

"Not enough" means that I should get a better circle with less blurring.
