If any of y'all don't think the processor can or does make a difference to colour, you clearly were not around Canon during the big DIGIC II crisis. Go look up the history of that processor and its cameras. Note they all used different sensors and different ADC (as was prior to ADC being physically encapsulated within the CPU housing), but they all ended up with the same (raw) colour (accounting for sensor size variations, of course) and that DIGIC II-specific colour is something that is still frequently requested (especially for video) and the DIGIC II bodies have managed to hold their value better (relative to age) than the DIGIC III bodies as a result.

 
In any case, at least we're now (mostly) in agreement that it's not just the sensor responsible for producing everything, which was the original point being made.

Again to be precise, the processor does not have any impact on the final image.  The lens, focusing mechanism, exposure mechanism, sensor, all of the analog circuitry, A/D converters, algorithms (firmware/software) used by the processor to process images, etc. have an impact on image, but the processor itself does not.

As Don stated, the processor just impacts the speed and power used.

"Everything that makes up and is used by the processor matters... but the processor doesn't matter."

... You two realise how you're contradicting yourselves there, right? Or did you skip the earlier part of the thread? We've already gone over how everything other than the sensor itself is encapsulated by the processor now (and this has been the way for over a decade now).

Problematic is that some of which “we” have gone over is bad information buried in good, for example that the basis for which we call dynamic range is the processor throwing away data from adjacent pixels of equal magnitude, when it is in actuality a function of full saturation and the lowest meaningful signal (i.e. where SNR is greater than 1).

What is lost in all this is that a processor merely does what it’s told to. It’s a series of logic gates configured programmatically by people. If you took the same logic from a digic 5 chip and ported it to digic 2 (assuming the image fits), they would act the same on the same supplied compatible data.

I think I've been trolled!!  Either that or these people are lumping way too much stuff into their definition of a processor.  Apparently including some "magic"!
