ISAPS is a scene-recognition technology developed by Canon for digital cameras. The latter is useful at tourist spots where there may be many people around who are not intended to be the subject of the scene. It reverts to the AiAF system if the subject is either not detected or not deemed to be a subject (based on the iSAPS database). New featuresĭIGIC III provides face detection AF/AE, which finds and tracks up to nine faces at once and controls exposure and flash to ensure proper illumination of the faces as well as the rest of the frame, reducing the detrimental effect of overexposed or darkened faces in a photo. Additionally it has a 14-bit A to D converter providing greater bit depth than previous versions. It also provides higher resolution for their LCD screens. 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. 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. Additionally, Canon claims DIGIC II improves color, sharpness, and automatic white balance with its CMOS sensor in its digital SLR camera line. It can write to memory card at speeds up to 5.8 MB/sec. It has been used in some advanced consumer-level cameras and many digital SLRs such as Canon EOS 5D and Canon EOS 30D.ĭIGIC II uses high-speed DDR-SDRAM, which improves startup time and AF performance. DIGIC II also improved upon the original by adding a larger buffer and increasing processing speed.

It consists of three separate chips: a video processing IC, an image processing IC and a camera control IC.ĭIGIC II is a single chip system introduced in 2004, unlike the first DIGIC, that allowed for more compact designs. The original DIGIC was used on the PowerShot G3 (Sep 2002), Canon S1 IS (Mar 2004), A520 (Mar 2005), and other cameras.
