context_page_description: Digital Imaging Integrated Circuit is Canon Inc.'s name for a family of signal processing and control units for digital cameras and camcorders. DIGIC units are used as image processors by Canon in its own digital imaging products. Several generations of DIGICs exist, and are distinguished by a version number suffix.
  Currently, DIGIC is implemented as an application-specific integrated circuit designed to perform high speed signal processing as well as the control operations in the product in which it has been incorporated. Over its numerous generations, DIGIC has evolved from a system involving a number of discrete integrated circuits to a single chip system, many of which are based around the ARM instruction set. Custom firmware for these units has been developed to add features to the cameras.
context_section_description: The DIGIC III Image Processor, introduced in 2006, was advertised to deliver improved image quality, faster operation and extended battery life compared to its predecessor. DIGIC III provides a faster interface to the SD memory card for the Canon PowerShot G7 and G9, SD750, SD800, SD850, SD900, SD 1000, A560, A570 IS, A590 IS, A650 IS, A720 IS, A495, EOS XS/1000D, EOS XSi/450D, EOS 40D, EOS 1D Mark III, EOS 1Ds Mark III, and S5 IS.
