[TriEmbed] Camera Advice

I'm working on a system for my bird feeder that would detect birds, take
photos of them and put these photos up online.  I assembled a working
prototype using a Raspberry Pi (with a WiFi dongle), a passive IR sensor
and a Logitech webcam, but it suffers from two drawbacks:

   1. The power consumption of the Pi is too large to permit long-term
   operation on battery or solar power, restricting installation options.
   2. The image quality leaves a lot to be desired.  (Here's an example

To solve issue 1 while keeping WiFi connectivity easy, I'm looking into
replacing the Pi with an electric imp <https://electricimp.com/>.  I'm not
sure what to do about the camera, though.  Adafruit sells a camera
accessible via serial port <https://www.adafruit.com/products/397> that can
be made to work with the
but capturing quality stills is not its strength.  The excellent built-in
iPhone cameras can be bought surprisingly cheaply on
but I'm not sure how to get them to talk to anything other than an iPhone.
 Another possibility might be buying and cannibalizing a cheap digital
but again I don't know if the modules inside could be interfaced with a
standard microcontroller.

What would you recommend?  What's the best way to get a reasonably priced
camera that takes high quality stills and can be easily controlled through
a standard bus?

Thank you for your help!
