    They aren't really specific about how the camera works. I wish
    however they would stop pretending resolution is proportional to pixel
    count instead of being regulated by linear pixel count.

    Doubling resolution, being able to see an object 1/2 the size of that
    just seen requires that the linear pixel count be doubled. This is a
    quadrupling of pixel count of the sensor. A doubling of the pixel count
    (e.g. from 12 to 24MP) only increases resolution by 50%.

    Oh I see - 41% really.

    And not even that if the lens is crap. I have a "lipstick" video camera,
    with "full HD" video, that is well below decent SD video quality even when
    recording 1920x1080p. :-(

    According to DARPA, it's a system
    "...that provides the warfighter a minimum of 65 VGA video windows
    across the field of view."

    <http://www.darpa.mil/>, search for "argus-is"

    Which sounds like multiple smaller sensors. The accompanying sample
    image seems to show stitching artifacts, as well.

    Ah, as usual, Aviation Week has the dope:

    The 1.8-gigapixel sensor has four optical telescopes, each with 92
    5-megapixel focal-plane arrays - cellphone camera chips, says
    BAE. The airborne processor combines the video output from all 368
    arrays together to create a single mosaic image, with an update rate
    of 12-15 frames a second.

    <http://www.aviationweek.com/>, search for "argus-is", choose "blogs".
