The Cadillac CT6 sedan will take on the likes of the Mercedes-Benz S-Class and BMW 7 Series when it launches towards the tail-end of 2015, and as part of its technology package, the luxury model will offer a digital mirror that live streams imagery from a camera mounted out the back.

The digital 'mirror' has a resolution of 1280 by 240 pixels and, according to GM, improves the driver's rearward field-of-vision by about 300 per cent. Travis Hester, the CT6's chief engineer, says that live streaming mirror "eliminates any rear seat, rear pillar or passenger obstructions, allowing the driver an unimpeded view of the lanes behind and traditional blindspots".

The system's high definition rear camera has been fitted with hydrophobic coating to keep it water free. Unlike many wide-angle reversing cameras, Cadillac's new live streaming mirror shouldn't present a fish-eye world view as the system has been programmed with a de-warping function.

Indeed, Cadillac says that it has been awarded 10 patents in total, including one each for wide angle image calibration, glare reduction and camera hardware design.

A toggle switch at the bottom of the mirror allows drivers to switch off the live streaming function, transforming the CT6's high-tech rear mirror back to a more traditional electro-chromatic, or self-dimming, mirror.
