It's neat that this is possible. It was demonstrated in the 1960s, but nobody could afford the CPU time back then.
The intensity range of the image limits how much deblurring you can do. If the range of intensities is small, after blurring, round-off error will lose information. Also, if the sensor is nonlinear or the image is from photographic film, gamma correction needs to be performed before deblurring.
