CNET: I3A President Lisa Walker presented a new 5-star rating system for phone cameras at ISE 2011. The system is meant to give a more objective measure for cameras quality.
"The test combines a host of technical measurements--detail, sharpness, chromatic aberration, lens distortion, and more--then links that analysis with subjective human assessments to ensure the measurements really are relevant. A detailed formula boils the various factors down into a single rating.
The ratings likely will come with a matrix that shares a bit more detail about the camera performance for those who want more than a handful of stars. The matrix as presently designed shows a variety of shooting styles--action, landscape, portrait, macro--fare when photos are presented on small or large prints or shown on mobile phones or TVs:"
