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.

Rich if you want something to play with try browsing this store.
Unfortunately most of what can be found here is, um, ...er plastic.

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.
