The Canon HS SYSTEM lets you take bright, clear photos in an even wider range of shooting situations. Beautiful low-light shots are possible with minimal noise and maximum detail in highlight and shadow areas. The system is the result of two technologies brought together in PowerShot cameras: a high-sensitivity imaging sensor, which is able to capture more light; and the DIGIC Image Processor, which actively reduces noise with high-speed image processing. The 16.1 Megapixel Canon CMOS sensor in the PowerShot ELPH 320 HS incorporates advanced light reception technology that enhances sensitivity. The new DIGIC 5 Image Processor provides a major boost in noise reduction, expanding the usable ISO range to an amazing high of ISO 3200. The Canon HS SYSTEM thus lets you use higher shutter speeds to capture clearer images with reduced noise and blur.
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.
