DIGIC DV III is Canon's most advanced HD image processor ever, helping to deliver enhanced image quality, true color production for both video and photos, and a sophisticated noise reduction system for exceptional low-light performance. It is also the high-speed engine which powers a variety of Canon technologies including Genuine Canon Face Detection and Advanced Auto Exposure system.
Plus, the Canon DIGIC DV III Image Processor allows continuous shooting of digital photos with the VIXIA HF20. You can also enjoy faster processing of your images to your memory card (1.4x normal card; 2.5x Hi Speed card). In addition, it helps lower power consumption for longer battery life.
