Echo, focal blur and motion blur are all instances of convolution. That 
means, hypothetically, that by applying a suitable *deconvolution*, you 
should be able to get back the original signal.

Question: Is it actually feasible to do this in the real world?

If I have an image with camera shake, can you really apply some math to 
it and get back the unblurred image? Or is that still the domain of 
science fiction?
