I think is really interesting:
A digital camera which uses an array of microlenses just in front of the
image sensor, to produce a little fish-eye-like image in the photodiodes
immediately behind each lens. Then throw some intense signal processing
at the image and it is possible to create from it multiple pictures,
each with a different focal length.
I had a quick look at the thesis behind this, by Ren Ng in 2006 :
This technology apparently has its roots in microscopy.
I want one . . .
