Motion-detection technology in digital cameras enables you to capture clean, sharp images.

Motion detection for a digital camera is based on advanced image recognition technology that detects subject movement and appropriately adjusts the shutter speed, aperture settings and optimal sensitivity to capture the ideal shot. In addition to motion detection, many digital cameras also detect face, scene and smiles. Some cameras have built-in GPS systems with motion sensors to track the autonomous positioning of the camera user. With this technology, pictures can be geographically tagged and imprinted anywhere in the world.
Canon
Canon's PowerShot series of digital cameras boast of its DIGIC 4 Image Processor, a superior technology in face, scene and motion detection to capture clear, crisp and detailed pictures. Face detection enables the recognition of human faces in the picture and automatically configures the camera to alter its focus and exposure. Scene detection enables the identification of up to 22 scenes based on people, distance and brightness and allows the camera to optimize the scene's brightness and color. The PowerShot SD790 IS, PowerShot SD770 IS, PowerShot G10, PowerShot A590 IS and PowerShot SX10 IS are examples that deploy this technology.
Casio
The Casio Exilim series of high-speed digital cameras boast of the capability to capture 60 frames per second within the press of a button. With this feature, you can capture a moving subject and review all 60 frames and select and save the one that best captures the moment. This feature is captured in these models: EX-FH100, EX-FC100, EX-FC150 and EX-FH20, among others. Casio's Multi-motion image processing technology lets you record multiple moving images and combine them into one image that displays the motions frame by frame. This feature is available in EX-FH20, EX-G1, EX-FC150 and EX-FH100, among others. The Exilim cameras also boast of being the world's first cameras with a built-in GPS to geographically tag photos and videos based on the camera user's position.
Nikon
Nikon's COOLPIX series boast of imaging technologies to detect motion of the subject in the picture, tracking moving subjects in the image and compensating for horizontal and vertical movements of the camera user. When motion is detected from either the subject or the user, via camera shake, Nikon's image technology selects a faster shutter speed and higher light sensitivity. When capturing a scene where the subjects are constantly moving, Nikon's image technology uses a contrast detection system to maintain focus on the subjects.
Sony
Sony's Cyber-shot and NEX series of digital cameras are equipped with motion-detection technology, which Sony markets as Anti Motion Blur mode in the NEX cameras. This technology corrects for subject movement by capturing as many as six images in a fraction of a second and combining the data from these images to produce a single clean and sharp image that minimizes subject blur. Sony's Cyber-shot series are equipped with both motion and face detection technologies that adjust light sensitivity and increase shutter speed. Its Smile Shutter technology enables these cameras to detect and capture smiles when they happen.
