Advanced bokeh computation?

[Marsu42]

I was just reading about bokeh on wikipdia, and stumbled upon this sentence which unfortunately isn't qualified further (see https://en.wikipedia.org/wiki/Bokeh#Emulation):

Some advanced digital cameras have bokeh features which take several images with different apertures and focuses and then manually compose them afterward to one image.

Can someone please explain which these "advanced digital cameras" might be and how the post-processing assembly works?

If I find this interesting, it isn't that difficult to write a Magic Lantern module which achieves the same thing with a click of a button - aperture bracketing and focus bracketing are both already included, they just need to be combined.

This is the only thing I'm aware of that does that:

I have a Nexus 5 and I have played with it some, but not enough to be of any help.

This is a pretty cool article. Thanks for the link mackguyver.

Manufacturers can post subtle advertising to Wikipedia formulated as information. This seems to fit the pattern. Its common and neither good or bad, but its not any sort of a standard definition.

Seems a kind of evolution of the Lytro concept (https://www.lytro.com/): several images with focus at different distances... or maybe not. :-[

Yes, kind of, but as a software solution which could be simulated with one of our dslrs (see link above, thanks, mackguyver!). But unless there is a normal pc application that can assemble these shots, it's no good writing a Magic Lantern module that does focus and aperture bracketing at the same time.

Looks good, though, certainly better than a simple gaussian blur. I imagine it bests dedicated "bokeh" plugins for PS as these only have access to one single shot and cannot really simulate an optical blur.
