    Abstract: Methods and apparatus provide for receiving an image to be displayed on the head-mounted display unit generated in a first frequency by an image generation apparatus using information relating to at least one of a position and a rotation of the head of a user who wears a head-mounted display unit, where the information is acquired at a certain point of time; correcting the image using updated information relating to at least one of the position and the rotation at a different point of time, where the receiving and correcting includes receiving updated information relating to at least one of a position and a rotation in a second frequency corresponding to a frame rate of the head-mounted display unit, and performing multiple times of correction of the image in the first frequency using a plurality of the updated information relating to at least one of the position and the rotation received in the second frequency higher than the first frequency.

    Abstract: A method of generating an image of a subject in a scene includes obtaining a first image and a second image of a subject in a scene, each image corresponding to a different respective viewpoint of the subject, each image being captured by a different respective camera, where at least some of the subject is occluded in the first image and not the second image by virtue of the different viewpoints, obtaining camera pose data indicating a pose of a camera for each image, re-projecting, based on the difference in camera poses associated with each image, at least a portion of the second image to correspond to the viewpoint from which the first image was captured, and combining the re-projected portion of the second image with at least some of the first image so as to generate a composite image of the subject from the viewpoint of the first image, the re-projected portion of the second image providing image data for at least some of the occluded part or parts of the subject in the first image.

    Abstract: Methods and apparatus provide for acquiring information relating to at least one of a position and a rotation of a user's head wearing a head-mounted display; generating an image for the head-mounted display using information relating to at least one of a position and a rotation acquired at a certain point of time; and a correcting process includes receiving updated information relating to at least one of a position and a rotation at a different point of time and correcting the image generated using the updated information. The generating the image includes using the information relating to at least one of the position and the rotation in a first frequency; and the correcting includes receiving updated information relating to at least one of a position and a rotation in a second frequency corresponding to a frame rate of the head-mounted display. The correcting includes multiple times of correction of the image generated in the first frequency using a plurality of the updated information in the second frequency, which is higher than the first frequency.
