PROBLEM TO BE SOLVED: To provide an image processor, capable of obtaining a display of an object free from sense of discomfort by mutually associating attitude change with position change of the object. SOLUTION: This image processor comprises a center-of-gravity position calculation part 30 calculating a center-of-gravity position of the object based on motion data at predetermined time intervals; a center-of-gravity movement quantity calculation part 32 calculating a movement quantity of the center-of-gravity position of the object per predetermined time; and a position/attitude determination part 34 determining the position of the object based on the center-of-gravity position of the object when the movement quantity per predetermined time of the direction separating from a field object in the center-of-gravity position exceeds a given threshold, and determining the position of the object based on the position of the contact part with the field object of the object when the movement quantity per predetermined time of the direction separating from the field object in the center-of-gravity position is less than the given threshold.
