For many years, Samsung’s smartphone cameras have produced some of the best photos on a mobile device, giving it an edge in marketing over the competition (especially over Apple and the iPhone).
The patent (published this week and reported on by Ilse Jurrien) comes from Samsung Electro-Mechanics and describes the techniques used in a new camera module for smartphones. It uses multiple lens elements to increase the image quality, but this has traditionally led to more internal reflections and lens flares.
The patent describes the use of a broad band anti reflection layer (BBAR) on one of the lens elements. This is expected to reduce the reflections on the treated lens to under one percent, allowing Samsung to increase the quality of the image and reduce lens flare and ghosting
