 Canon's DiG!C doesn't merely take an image, it captures everything in sight. DiG!C is a major advancement in image processing technology. This is a unique single-chip that acts as the brain in Canon digital cameras. It takes millions of individual pieces of brightness data and rapidly assembles them into a final image with accurate colour, detail and a minimum amount of artifacts or 'noise'. What is DiG!C? Put simply, DiG!C replicates the human sense of sight. The lens of a digital camera is like a person's eyes, gathering an image and focusing it upon the retina at the back of the eyeball. A digital camera's lens focuses the image onto a light-sensitive image sensor. In both cases, the light needs to be processed into a recognisable final image. In human beings, it is the visual cortex in the brain that performs this vital task, and in Canon digital cameras, it is the image processor. So while many people think the number of megapixels is the key to image quality, its signals are totally unrecognisable as an image until they've been gathered and processed. To process a digital imaging file, many complex calculations have to be performed on a pixel-by-pixel basis. DiG!C's processing capability gives it a huge advantage in speed and performance. This enables it to reproduce colour as the human eye sees it. We call this unique innovation Memory Colour. Autofocus is also more precise and lets you capture every moment with complete clarity. Additional functions such as; control of the CCD imaging sensor, exposure control, Autofocus Management, Auto White Balance calculations and CompactFlash card control, ensure accurate exposure.
High speed delivers exceptional image quality In signal processing, the more often algorithms are calculated, the better the image. Because DiG!C operates at extremely high speed, complex algorithms that improve image quality can be executed effortlessly. In contrast, the general-purpose processors used by other camera makers, struggle to execute the complex calculations, so processing times take longer. As a result, they discard many algorithms to avoid sacrificing speed. Canon takes a no compromise approach and delivers unsurpassed image quality at blistering speed. In addition, DiG!C's speed helps suppress noise at every stage of image and signal processing, delivering a higher quality original image. High performance photography at the touch of a button. As DiG!C processes at a faster speed than other processors, it delivers a faster response the second you press the button to fire. Autofocus occurs faster letting you capture the moment in an instant. Accurate exposure is also assured, preventing white saturation that often occurs with other processors. DiG!C powers stills and video quality. DiG!C also adjusts from digital to still format to deliver the best results. Since video and photos have different colour requirements, DiG!C DV uses two different image processing techniques. This optimises video quality for viewing on a TV, and still image quality for printing or computer display. The result: both video and still images have more accurate colour, wider tonal range and finer detail. The Canon difference Canon's advantage comes down to technological balance. Only Canon has a long history in imaging, and such an in-depth knowledge of advanced signal processing technology to give users DiG!C. You'll find DiG!C in the high-end EOS 20D as well as the the PowerShot and IXUS series. This allows each Canon camera to produce the highest image quality in its class. With Canon's lens technology, DiG!C goes beyond a simple megapixel comparison to deliver the finest performance in digital still and video cameras. Experience the difference for yourself.
