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.
