in maintaining consistency in image rendition across the camera’s entire ISO sensitivity range.
This means that, regardless of how the ISO sensitivity fluctuates, the camera must produce similar rendition of the image at all sensitivity levels.
To achieve this, we had to fine-tune the camera by optimizing the consistency in noise and sharpness.
Working to minimize the generation of chromatic noise in the high-sensitivity range sometimes results in unfaithful color reproduction.
We were able to develop an original image processing technology that assured distinctive PENTAX rendition even at super-high sensitivities. In the PENTAX K-3 Mark III, we moved a step closer to achieving the ideal PENTAX image quality by incorporating the PRIME V imaging engine and the new-generation accelerator. While delivering beautiful images with smooth outlines and true-to-life colors,
the camera also prevents incorrect adjustment of black levels. It even provides a super-high top sensitivity of ISO 1,600,000. Because it also provides a selection of Custom Image modes and a wide range of adjustable parameters, the number of combinations with ISO sensitivity settings is almost limitless. By conducting a series of sensibility evaluations to analyze a great number of images captured by our image quality designers, and by using the evaluation results for further upgrading, we were able to successfully
fine-tune the camera and produce consistent image rendition at all ISO sensitivity levels.
...Eli, sanoisin kyllä. "extra fine sharpness II" tarkoittanee lähinnä jpg kuvaa, mutta tekstistä saa sellaisen kuvan, että " PRIME V imaging engine and the new-generation accelerator" käsittelee myös RAW dataa, samalla tapaa kuin KP ja K-1II malleissa...Tai sitä on kehitetty edelleen.
