1. Introduction
This manual provides essential information for the safe and effective use of your Canon Digital IXUS 100 IS digital camera. Please read this manual thoroughly before using the camera and keep it in a safe place for future reference.
The Canon Digital IXUS 100 IS features an exquisite 18.4mm stainless steel casing. Its 12.1-megapixel high resolution ensures captivating detail reproduction for large prints or cropped enlargements. The Canon DIGIC 4 image processor provides high speed and excellent image quality with vibrant colors and minimized noise. The DIGIC 4 processor also offers optimized motion and face detection technology. Motion detection distinguishes camera shake from deliberate subject movement, adjusting settings to reduce blur. Face Detection continuously focuses on faces, offering benefits like an automatic timer for group photos and red-eye correction. The new Blink Detection feature identifies and indicates images where subjects have blinked. The 2.5-inch, 230,000-pixel PureColor II LCD provides excellent image preview and detailed review. An optical viewfinder is available for classic image composition and battery-saving operation. Despite its ultra-slim size, the Digital IXUS 100 IS includes an HD video function, recording sharp high-definition movies (1280 x 720) for playback on an HD TV via the integrated HDMI™ interface. Versatile recording modes include auto, portrait, night shots, children and pets, indoor, sunset, fireworks, beach, snow, digital macro, and color change. My Colors photo effects include Vivid, Neutral, Sepia, Rich Blue, Rich Green, and Rich Red.
