A head mounted display apparatus includes a display unit by which an outside world can be transmissively visually recognized, including: a superimposition image display control part that allows the display unit to display predetermined images in correspondence with positions of subjects in the outside world transmissively visually recognized, a view range movement information acquisition part that acquires view range movement information representing a motion of the display unit, and a subject movement information acquisition part that acquires subject movement information representing a relative motion of the subject to the display unit. When the acquired view range movement and acquired subject movement information are substantially not matched, the superimposition image display control part estimates a relative position of the subject to the display unit after a predetermined time based on at least the subject movement information, and determines a display position of the predetermined image based on the estimated relative position.
