FotoNation Dust Removal Technology

Cameratown: The FotoNation Dust Removal Technology automatically removes dust from digital images. FotoNation has been awarded a U.S. patent for this technology and has 10 additional patents pending in the U.S., Europe, and Japan. FotoNation eliminates dust from images using in-camera software which distinguishes between dust and real detail in the photo. The software dynamically builds a map of every dust-spec and then tracks changes and movement of the dust particles to distinguish dust from the details of the photograph. The technology has been designed to scale across multiple platforms is optimized to run as embedded software in digital cameras and mobile phone cameras as part of image acquisition.

Dust is a significant problem in the production of camera modules for mobile phones. Mobile phone camera modules typically consist of an image sensor hermetically sealed inside a plastic package with a lens and image processor. Dust contamination on the image sensor during assembly of the camera module is a costly source of reduced manufacturing yield. The FotoNation Dust Removal Technology can increase manufacturing yield and image quality for these products.
