DiGC Image Processor

Between the capture and recording stages is image-processing that determines how the signals from the sensor are translated into a viewable image. In the 5D Mark II, the processing is performed by the DiG!C 4 image processor. Major advances responsible for the speed, advanced image-processing capabilities, and lower power consumption over the DiG!C II processor include lower noise image development at all ISOs, higher-speed image-processing, improved highlight and shadow details, extended dynamic range, more accurate colors that maintain fine details and improved performance, and zero loss of shooting speed while handling larger 14-bit RAW images.

High ISO noise reduction is also improved, yielding higher image quality and allowing cameras to maintain fast maximum shooting speeds and burst rates, expanding the functions and speed of the Auto Lighting Optimizer, and incorporating processing algorithms for Peripheral Illumination Correction data available for 80 Canon lenses. With storage capacity for up to 40 lenses, the camera ships with data for 26 of the most popular lenses from Canon. If need be, you can delete unused lens data via EOS Utility software included with the camera to make room for adding additional lenses. The new DiG!C 4 image processor significantly raises the bar with increased ISO ranges in normal and expanded modes and adds an Auto ISO range feature of 100-3200.
