Not only has Pentax improved in-camera image processing but they appear to have overtaken some of the competition, the amount of detail delivered is about as much as we could expect to see from a six megapixel CCD. On top of this they’ve also taken the sensible compromise of using a minimal amount of noise reduction and not turning down sharpening at higher sensitivities which means you get almost as much detail at ISO 1600 as you would at ISO 200. This combination means that assuming the ‘input image’ is sharp (good lens and/or stopped down slightly) you’re going to get a great detailed image
