"The PowerShot S100 features the most powerful implementation of the HS System yet. Building on the PowerShot S-series' reputation for providing high-quality, low noise images in low light, the enhanced HS System optimally combines DIGIC 5 processing with a high-sensitivity 12.1 Megapixel 1/1.7-type CMOS developed using Canon EOS sensor know-how â€“ providing an even more powerful basis for low light photography. Supporting a maximum ISO of 6400 at full resolution, the camera fully-utilises the high performance of the CMOS sensor and the power of DIGIC 5 to reduce image noise â€“ offering the reassurance of excellent image quality in all conditions.
Designed to achieve new and advanced levels of image quality, DIGIC 5 analyses four times more image information to create each pixel, recording more detail and colour from a scene than ever before. Processing speed is also six times faster compared to the previous processor, efficiently managing the increase in scene information and simultaneously reducing the appearance of image noise by up to 75%
Using the power of the DIGIC 5, the PowerShot S100 is ideal for capturing fast-moving action. High-speed Burst HQ is perfect for everything from sports to parties, capturing a rapid sequence of eight full resolution shots at up to 9.6 shots/sec. For recording the drama of high-speed action, Super Slow Motion Movie mode also records videos at 240 fps (QVGA quality) or 120 fps (VGA quality).
For easy shooting in a range of situations, Canon's Smart Auto mode ensures great results by selecting the optimum settings for a scene from 32 variables. New Multi-area White Balance also makes images look more natural by detecting scenes with two different light sources and applying area-specific white balance correction. For instance, when shooting a portrait with flash under tungsten lighting, the camera will simultaneously apply tungsten white balance to the background and flash white balance to a person's face, ensuring both the subject and background look natural."
