Apple Buys InVisage Technologies to Focus on Low Light Mobile Photography

One of the biggest complain about mobile cameras has been that they are not good at low light photography. However,  it looks like Apple wants to change that as they bought InVisage Technologies - a company focused on developing QuantumFilm Image Sensors that specialize in capturing more light in thinner camera modules.

InVisage describes their technology QuantumFlim as a photosensitive layer that relies on InVisage’s newly invented class of materials to absorb light; specifically, the new material is made up of quantum dots, nanoparticles that can be dispersed to form a grid once they are synthesized.

In a QuantumFilm pixel, light passes through the color filter array, and is then detected by the quantum dots in the QuantumFilm layer. The metal wiring represents the sensor’s electrical circuitry. The higher positioning of the photosensitive layer allows the QuantumFilm pixel to detect more photons, store more electrons (and therefore more photographic information), and reproduce colors more accurately—all with a thinner camera module.

It will be interesting to see how soon Apple can bring this technology to the iPhones. As it will change mobile photography forever by removing its biggest limitation.
