The bayer sensor is the same. Only the processing has changed.

actually the sensor has changed in some cases. there have been
variations on the filters, including cmyg, rgbe (emerald) and even rgbw
(white - no filter) patterns and i think one sensor used two shades of
green but i don't remember which one off hand.

None of which is a Bayer pattern sensor, any more than coffee or
tea is water, even though coffee and tea are based on water.

unless you are a sensor designer or a raw software developer, the
sensor and processing can be taken as a unit.

You only own P&S cameras that don't output RAW?
Well, I don't ...

*all* bayer sensors
*will* have demosaicing done to provide an image to the user.

Wrong. You can e.g. provide a 2 MPix greyscale image from the red
(or blue) pixels of an 8 MPix beyer sensor without demosaicing.

There
are plenty of different algorithms that can be used with the usual
tradeoffs of processing speed vs. visual performance.

absolutely, and not surprisingly, the detractors pick the absolute
worst possible method, so bad it's not ever used.

You probably can't say for sure what methods are used or not used.

the exact algorithm, no, but there is quite a bit of available
information on bayer processing that *is* available to the public.

Which says about exactly nothing about what specific things
are done in any concrete implementation. Unless you want to
argue hypothetical things (like worldwide peace) you have to
base your arguments on the reality as it happens to be.
