  • Real-time removal of IR LED reflections from an image
    Patent number: 11179035
    Abstract: A system for the real-time removal of reflections from an image including a head wearable device, a first illuminator, a second illuminator, at least one camera and a reflection removal processor. The first and the second illuminators are configured to provide light and to operate one at a time alternately. The at least one camera is configured to capture a first image of the eye of the user when the first illuminator is in an ON state and a second image when the second illuminator is in an ON state. The operation of the at least one camera is synchronized with the operation of the first illuminator and the second illuminator. The camera captures images and transfers them to the reflection removal processor that provides real-time removal of reflections by combining the first image and the second image.
