Refocusing in post

Very cool. Didn't a Canon prototype/concept feature something like this a while ago? Looks very interesting but I'd be surprised if the noise/IQ is up to scratch at first
 
Awesome! Light field cameras are very interesting indeed, I guess there's quite a few start ups trying to commercialise the technology now?

Here's a good artical I read a few months back regarding small arrays.

Isn't the idea behind that is the sensor takes loads of photos of the same frame but at different DoF plane?

Not as far as I am aware. In addition to recording the data that current sensors do, it also records the angle at which the photons are hitting the sensor. Combine this data with very clever maths, it can work out dof and focus.

.......Any potential for holograms? I wonder....

But surely there is only 1 angle of light that hits the sensor, through the lens in front of it. It is not a stereo image but one dimensional one.

take a look at the video in the second link raymond.

The video that shows a 3D ish image? It doesn't explain how it works out the spacial elements if the light is hitting the sensor from 1 direction. You need a stereo image to judge distance and work out angles.

I don't think it is a single lens and sensor though. It is morel likely to be an array of smaller lenses and sensors.

Apparently the sensor is about 16MP but the final output photo is only 0.1 to 0.3MP!

Someway to go before the technology becomes useful unless the purpose is for face-book updates!

That explains it then, so it does that a photo at various focal plane and have that data rather than an algorithm that works out the missing data....the latter seems too good to be true.

and 0.1mp is lower res than VGA isn't it?
