Fujifilm has an innovative new sensor layout for the just-released X Pro-1 camera, which they say is "inspired by the natural random arrangement of the fine grains of silver halide in film":
Since the arrangement is more aperiodic (less repetition), it's unlikely to cause moire artifacts (which occur when there's a misalignment between a pattern on the sensor and stripped pattern in the recorded image). This lets Fujifilm skip the low-pass AA filter, which traditionally adds blur to combat this issue.
They add "Also the presence of an R, B and B pixel in every vertical and horizontal pixel series minimizes the generation of false colors and delivers higher color reproduction fidelity."
How does conversion of this type of RAW image work? Is it essentially like Bayer demosaicing algorithms but a little more complicated, or does it require different approaches altogether?
In the latter case, it seems like there's a large risk that third-party RAW conversion support will be unavailable or rare, but if the same basic algorithms can be used I expct it to be less of a problem.
Other than that software support issue, are there potential downsides as well as the advantages Fujifilm claims?
