Abstract: An information processing apparatus acquires, using an image obtained by capturing a device including a light-emitting marker with exposure times shorter than a time corresponding to one frame, information regarding a position and a posture of the device. The light-emitting marker is caused to emit light for light emission times equal to or shorter than the exposure times. The information processing apparatus causes the light-emitting marker to emit light in a predetermined flashing pattern, and identifies the exposure times on a time axis of the device on the basis of whether or not the image appears in the captured image, to thereby synchronize the exposure and the light emission.

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 operated by a user. The image is generated for display on a display unit viewed by the user. 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: 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.
