Canon DIGIC 5 Image Processor
The latest-generation Canon DIGIC 5 Image Processor brings phenomenal increases in processing speed and power. Improved chip architecture and algorithms deliver greatly expanded functionality with further refinement in image quality. Improved noise reduction produces clearer images when shooting in low light at high ISO speeds. Enhanced i-Contrast performance adjusts differences between light and dark areas to achieve even more natural-looking results. The faster processing speed also results in faster continuous shooting capability while maintaining full image quality. The DIGIC 5 Image Processor also makes possible a new, highly advanced automatic white balance system. Whereas conventional white balance makes an overall adjustment based on a single type of light source, the new Canon Multi-Area White Balance analyzes several areas of the image to determine whether different adjustments are needed, for example, for the main subject and the background.
Designed to achieve new and advanced levels of image quality, the DIGIC 5 processor analyses four times more image information to create each pixel, thus recording more detail and colour from a scene than ever before. Processing speed is six times faster compared to the previous (DIGIC 4) processor, efficiently managing the increase in scene information and simultaneously reducing the appearance of image noise by up to 75% (the new Powershot S100 as compared to the S95 at ISO 1600).
The Canon DIGIC 5 Image Processor is currently available in the following cameras:
Canon PowerShot S100
Canon PowerShot SX40 HS
