  • Patent number: 11119319
    Abstract: Provided is a head-mounted display 100 for displaying images transmitted from a rendering device 200. An orientation sensor 64 detects an orientation of the head-mounted display 100. An HDMI transmission/reception unit 90 receives frame data of an image to be displayed on the head-mounted display 100 and predicted orientation information of the head-mounted display 100 that is transmitted synchronously with the frame data of the image. A re-projection unit 60 corrects the frame data of the image on the basis of a difference between a latest orientation information detected by the orientation sensor 64 and the predicted orientation information so that the frame data of the image suits a latest orientation of the head-mounted display 100.
