Apple has acquired a startup dedicated to camera sensors called InVisage Technologies, according to TechCrunch. InVisage touts its QuantumFilm image sensor and specializes in capturing light using a thinner camera module.
Here you can read a brief description of the technology created by InVisage and of which Apple now owns.
QuantumFilm is a photosensitive layer that is based on the new class of materials invented by InVisage to absorb light; specifically, the new material is composed of quantum dots, nanoparticles that can be dispersed to form a grid once they have been synthesized. Like paint, this dispersion of solid materials can be deposited on a substrate and left to dry. In a QuantumFilm pixel, the light passes through the color filter matrix and is then detected by the quantum dots in the QuantumFilm layer. The metal wiring represents the electrical circuit of the sensor. The higher position of the photosensitive layer allows the QuantumFilm pixel to detect more photons, store more electrons (and, therefore, more photographic information) and reproduce the colors more accurately, all with a thinner camera module.
As Apple continues to focus on improving the quality of the iPhone camera every year, it's easy to see what Apple's plans are for incorporating this technology into its hardware.
Apple currently relies on vendors for its cameras, but uses its internal image signal processor to control the sensors. Based on the description of its InVisage technology, you can imagine that Apple is developing its own camera modules that stand out for capturing light in thinner bodies. It will undoubtedly be a striking advance for Apple's mobile phone camera and its users will be grateful.
