    Hanrahan's system would be particularly useful for surveillance cameras, which must work at night but also need to have objects in focus at different distances from the camera.


    Sounds like the technology they already have in the TV show Las Vegas! Crappy TV predicts the future!

    Or Bladerunner, where Deckard is looking at the photo he found in the replicant's apartment.

    My personal faves are the CSI type shows where they can pull amazing detail from a tiny little reflection in a picture taken with a crap little camera.

    Amazing stuff...

    Do you really want a 90k sensor? Wouldn't it be easier to have multiple cameras.Still if it could be made to work at several megapixels could be interesting.

    Let me get this right.
    You have 90,000 lenses and detect the image for each, and that way use software to focus?
    So you have to store the image for each of the 90,000 lenses.

    My 5 MP camera has shots around the 1300 KB mark.

    So each photo is around 110 GB?

    Hang on, my camera uses JPEG compression which is lossy? Do you need to store the 20MB raw image for all 90,000 images? 1.6 TB per photo?

    Or just about any movie where the somebody announces "I'll just clean this up a bit". This has always pissed me off in movies.

    No, you have 90,000 extra sensors in front of the main sensor to detect the angle of the light rays coming in and use software to reconstruct the photo with everything in focus.

    Ahhh, so in real time, is in the exposure time of the shot, the camera can calculate the angle of arrival for all 5M pixels. Image size is perhaps doubled, as you store two values per pixel.

    Here is a better explanation the original source.90k microlenses in front of a multi meg sensor, stores information about direction and intensity for each microlens which can be deconvoluted to obtain whole image in focus.Ultimately still effectively have a 90k sensor.
