Abstract: Methods and apparatus provide for generating an image by way of acquiring information relating to at least one of a position and a rotation of a camera. The image is generated for display on a display unit. A rate at which the image is generated is at a first frequency, which is lower than a second frequency corresponding to a frame rate of the display unit.

Abstract: A method and system of generating an image of a subject from the viewpoint of a virtual camera includes obtaining a plurality of source images of a subject and pose data for each source camera or cameras that captured the source images. Virtual camera pose data is also obtained indicating a pose of a virtual camera relative to the subject. Each source image is distorted based on a difference in pose of the corresponding source camera and the pose of the virtual camera. A weighting is determined for each distorted image based on a similarity between the pose of the corresponding source camera and the pose of the virtual camera. The distorted images are then blended together in accordance with the weightings to form an image of the subject from the viewpoint of the virtual camera.
