Image processing chain in Digital Still Cameras

Nobody is perfect, neither are the components used in digital still cameras. Nevertheless the photographer wants to see the best quality image taken with his/her Digital Still Camera (DSC). Today the number crunching power of signal processors is high enough that many of the imperfections created by the lens and the image sensor can be easily corrected. For instance lens vignetting, defect pixels and color imperfections are no longer limitations to obtain high-quality results. The Digital Signal Processor (DSP) corrects everything, even the good pixels.
