I am planning to try to attend this talk too. I went to one of the
first talks on plenoptic cameras a couple of years ago: it was
fascinating.

The technology at that time demonstrated the potential capabilities of
what is possible when there is enough pixel resolution to capture
vector information as well as the spatial resolution and intensity
information of the incoming optical image. The prototype they were
experimenting with had a 36 million photosite resolution sensor and
output about a 4 Mpixel plenoptic image with vector information. In
other words, it took 12 pixels to record adequate spatial, intensity,
chroma and vector data for one output pixel. It did this by ganging a
12 pixel block under a single micro-lens on the sensor surface at a
time, and processing out the differences in image intensity across
those matrices of pixel blocks to derive the vector information.

Because you have the light vector information, you can actually,
really readjust the focus throughout the scene, both across the boards
and selectively, in processing. It's as if the camera lens were made
of a flexible glass that can be squeezed or stretched at any time.

Their notion at that time was that these types of cameras would become
a reality when about an order of magnitude more pixel resolution was
available at cost effective prices ... around 120-160 Mpixel was the
projection. At that time, pro SLRs with 10-12 Mpixel sensors were
surfacing, now pro SLRs with 24 and even 40 Mpixel are available.
We're on the way ...

It should be a fun talk!
