Canon developed the proprietary DIGIC (Digital Imaging Integrated Circuit) image processor specifically for use with its line of digital cameras. The technology combines the jobs of image processing and camera function control into one chip. Because it was specifically designed for use in digital cameras, it is also capable of handling JPEG compression/expansion; memory card control; LCD/Video control and processing; gain control (control of CCD signal amplification); Auto Exposure; Auto Focus; Auto White Balance control and most other functions of the camera or camcorder. The result is a product that offers faster and more powerful auto focus than ever before, faster image processing, longer battery life, and the ability to record 3-minute movie clips with sound.
The DIGIC chip’s high-speed processing enables Canon's exclusive iSAPS (an acronym for Intelligent Scene Analysis based on Photographic Space) technology that improves picture quality by "predicting" certain camera settings like focusing distance, exposure and optimum white balance based on zoom focal length, overall light level and tonal distribution data. With iSAPS, the PowerShot A80 camera can analyze a scene just before the image is made and in doing so, increase the speed and precision of the camera's autofocus, auto exposure and auto white balance.
