Originally, DIGIC technology was used on CANON S1 IS, A520 and few other cameras. It contains three individual chips like an image processing IC, a camera control IC and a video processing IC. Then came the DIGIC II processor, with a single chip having design that is more compact, faster processing speed by adding the buffer capacity.

In this blog, we are going to review on the Canon DIGIC III Image Processor. This delivers faster operation, long battery life and a superior image quality. It offers a faster interface for the SD memory card for G9, CANON PowerShot G7, S5 IS, EOS 1000D, A720 IS, A650 IS, A590 IS, A560, SD1000, SD900, SD850, SD800, SD750 and more.

It offers high resolution for its LCD screen with a new Face Detection AF/AE. This provides upto nine faces on the frame, which controls flash and exposure. It also ensures proper illumination on faces and reduces the detrimental effect of darkness and overexposed faces in the photo.

DIGIC III has a AiAF reverting system, which is based on iSAPS technology. This is called the original or real scene recognition technology, specially developed by CANON. Using the internal database, iSAPS works with this Image Processor to enhance white balance, focus speed, exposure and accuracy.

In 2007, the DIGIC III is also used in CANON’s SLR digital cameras. Then, Dual DIGIC III processor was introduced on CANON EOS-1D Mark III to obtain 10 frames/sec of capture rate. So, DIGIC III Image Processing technology is the latest form of revolution in CANON’s digital camera industry.
