Image is getting blury when Zooming In

I am trying to zoom to a image in my view. For that I used UIScrollView and in that scrollView I placed a ImageView. I had set min and max zoom scale of scrollview.

I used this code too..

- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView {
return imgView;
}
