A start-up called InVisage has unveiled new approach to digital camera image sensors. Its technology, called QuantumFilm, is four times more efficient at capturing light than traditional silicon-based image sensor chips, meaning the company's sensors will offer either higher sensitivity in low light or more megapixels in resolution.
The technology adds a new finely tuned light-sensitive layer on top of the silicon chip, according to the company. That layer is more efficient at converting incoming light into electrical signals, and the light isn't partially blocked by a microprocessor's metallic layers.
