摘要: 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.

A light receiving element includes a pixel which includes an SPAD, a first transistor configured to set a cathode voltage of the SPAD at a first negative voltage, a voltage conversion circuit configured to convert the cathode voltage of the SPAD upon incidence of a photon and output the converted cathode voltage, and an output unit configured to output a detection signal indicating the incidence of the photon on the SPAD on the basis of the converted cathode voltage. The present technology is applicable to a ranging system that detects a range in a depth direction to a subject, for example.

摘要: Provided is a method for compensating light reflections from a cover of a time-of-flight camera in an image of a scene that is sensed by the time-of-flight camera. The method includes receiving the image of the scene from the time-of-flight camera. Further, the method includes modifying the image of the scene using a reference image to obtain a compensated image of the scene. Pixels of the reference image indicate reference values exclusively related to light reflections from the cover of the time-of-flight camera. Additionally, the method includes outputting the compensated image.
