The PowerShot SX170 IS camera features Smart AUTO: sophisticated Canon technology that makes getting that great shot as simple as pressing the shutter button. Smart AUTO automatically detects scenes by assessing various factors in both the background and the subject. Detected scenes are analyzed using 32 predefined shooting situations. The camera then makes optimal settings to ensure the best possible image capture, whether you're shooting stills or video. Smart AUTO also includes Advanced Subject Detection, which allows the camera to detect and track non-human moving subjects like animals and vehicles. With Smart AUTO, all you have to do is frame your shot and capture away.
