Event-based camera with high-resolution frame output

Abstract

A high-resolution image sensor suitable for use in an augmented reality (AR) system to provide low latency image analysis with low power consumption. The AR system can be compact, and may be small enough to be packaged within a wearable device such as a set of goggles or mounted on a frame resembling ordinary eyeglasses. The image sensor may receive information about a region of an imaging array associated with a movable object, selectively output imaging information for that region, and synchronously output high-resolution image frames. The region may be updated dynamically as the image sensor and/or the object moves. The image sensor may output the high-resolution image frames less frequently than the region being updated when the image sensor and/or the object moves. Such an image sensor provides a small amount of data from which object information used in rendering an AR scene can be developed.
