This is a great teaser and the cameras sound like they have great potential. However, not yet enough information to understand the technology... Pelican's patents must be recent filings (less than 18 months) since I don't see them as pending applications. Even the term "array camera" is unclear in this context: how would the basic camera hardware differ from current mobile phone camera technology? Combined with the growing Instagram application, these new imaging capabilities could be a hit.
Eureka! The article makes much more sense once the photograph at the end uploaded (on a return visit) indicating that this is an "array camera" as in an array of small cameras which can be computationally combined to improve quality and depth perception while also allowing for a thinner phone. [I guess all cameras are some kind of array: linear array, 2D array, etc.] Maybe the reason my internet is so "fast" is that it cheats by selectively leaving out essential images.
