Really Canonrumors, you've gotten so desperate that you are going to publish something that is so obviously false?
There is 0.0% light field is coming to the EOS line. If you did any research on it[light field] whatsoever you'd know why this is the case.
it does not have to be lightfield technology.
the rumor is very vague.. could be about adding bokeh in post.
it could be possible that the dual pixel AF can deliver enough depth information to create a depth map. when i first read about dual pixel technology i instantly thought about this.
normaly the depth maps i create have a distance information for every image pixel.
the more roughly the image is approximated in the depth map image the more fake looks the post production DOF.
and maybe it´s possible to readout the relative distance informations for every pixel on (future) dual pixel sensors.
you could then use this information to do a fake bokeh in post.
but as i said such calculations are normaly slow (or they are fast but look bad).
but done right you can´t (99% of the people anyway) say for sure if it´s postproduction or real.
it all depends on how correct your depth map is and how good the algorithm to calulate the DOF.
of course this will not help to get out of focus parts into focus after the image was taken.
it only would help to simulate a f1.2 lens when you only have a f5.6 lens.
more like alienskin bokeh on steroids.
