Mini Camera Gets A Big Brain

Cameras are mounted everywhere in sports these days. During the Olympics we had underwater cams for swimmers and athlete's-eye views for bikes. Now there's a camera that could be mounted on a helmet to record not just the athlete's view but her heart rate, acceleration and loction, too.

Called the INCA, the camera has a processor as powerful as any PC, which allows a lot of functionality crammed into a space less than  three inches on a side. The INCA was designed by the Fraunhofer Institute for Integrated Circuits IIS.

4K resolution

4K is a resolution standard in digital cinematography and computer graphics. The name is derived from the horizontal resolution, which is approximately 4,000 pixels (this designation is different from those used in the digital television industry, which are represented by the vertical pixel count). There are several different resolutions that qualify as 4K. YouTube is the only video hosting service that allows 4K videos to be streamed as it allows a resolution of up to 4096 x 3072 (12.6 megapixels).
