InVisage, a company into development of digital devices is in last stages of inventing a new product that is named by them as QuantumFilm that has ability to make significant changes into the technology used by digital phone cameras. It can bring about some big changes onto small CMOS sensors on small form factor devices like camera phones.

However, looking into the technology of camera phones the biggest problem as faced by them is not the megapixel rating but the light to be captured by its sensors. So as much light you would have as better pictures you would able to capture with your camera. And it is CMOS sensors that determine the need of light as required by a phone camera.

QuantumFilm employs a custom-designed semiconductor material that can replace some of the silicon in image sensors and is used in CMOS cameras. This material that is based on quantum dots can capture much more light, and can work along with the existing CMOS manufacturing process.

Invisage says QuantumFilm can provide twice the light detection and twice the quantum efficiency of typical silicon-only sensors. The potential for QuantumFilm remains in the fact that now on manufacturers would able to keep their cameras with substantially better quality into their products without having to get into larger sensors or create a whole new manufacturing process.
