Mitsubishi uses multiple cameras to enhance HD video

Mitsubishi Electric of Japan has developed an innovative technique, which increases the resolution of HD video, by combining shots from multiple cameras into one super HD stream.

Mitsubishi is currently testing the technology at its research facility in Tokyo, using five video cameras capable of shooting high-quality images.

These are linked to computers with 3D graphics processors, which process the raw data. The camera images are analysed for differences and the input is mashed together to form a composite video, giving a substantially higher resolution.

Using five cameras and five PCs in this way produces video with four times the resolution of normal HD TV and it takes just 0.15 seconds to process and deliver the data.

According to Mitsubishi, the new system delivers video of as high a quality as that produced by commercial digital cinema. The technology could be used in surveillance systems and possibly in live TV broadcasts.
