The ultimate goal is to create a Frankencamera from widely available hardware at a cost that is accessible to those who wish to explore the platform, ideally under $1,000, a price most serious photographers will agree is pretty fair for serious photo optics. The prototype, assembled at Stanford, uses a TI processor running Linux, an imaging chip from a Nokia N95 phone, and Canon lenses. From there, users just need to start assembling the monster's many parts. For instance, one idea that has been extensively explored in the lab, but is still stuck there, is dynamic range expansion: taking multiple pictures of the same scene at varying exposures, and then compositing them into a single image in which each pixel is optimally lit. Computers in the lab can extend dynamic range. So can Frankencamera. But no commercially available camera can.
