    Abstract: A tracking system uses a dynamic vision sensor (DVS) operably coupled to the processor. The DVS has an array of light-sensitive elements in a known configuration. The DVS outputs signals corresponding to two or more events at two or more corresponding light-sensitive elements in the array in response to changes in light output from two or more light sources mounted in a known configuration with respect to each other and with respect to a controller. The output signals indicate times of the events and locations of the corresponding light-sensitive elements. The processor determines an association between each event and two or more corresponding light sources and fits a position and orientation of the controller using the determined association, the known configuration of the light sources and the locations of the corresponding light-sensitive elements in the array.

    Abstract: A tracking system includes a processor, a controller, two or more light sources and a dynamic vision sensor (DVS). The light sources are of known configuration with respect to each other the controller and turn on and off in a predetermined sequence. The DVS includes an array of light-sensitive elements of known configuration. The DVS outputs signals corresponding to events at corresponding light-sensitive elements in the array in response to changes in light from the light sources. The signals indicate times of the events and locations of the corresponding light-sensitive elements. The processor determines an association between each event and one or more of the light sources and, from that association, determines an occlusion of one or more of the light sources. The processor estimates a location of an object using the determined occlusion, the known light source configuration, and the locations of the corresponding light-sensitive elements in the array.

    Abstract: Disclosed herein is an image processing apparatus including: a captured image acquisition unit configured to acquire data of a captured image; a correction unit configured to refer to a displacement vector map, which is stored in a storage unit and represents, on an image plane, displacement vectors each representative of a displacement amount and a displacement direction of a pixel used when the captured image is to be corrected to a display image or calculate the displacement vectors to correct the captured image; and an image display controlling unit configured to cause the corrected image to be displayed on a display panel.
