Abstract

An object of the present invention is to obtain calibration data more easily in a VR (Virtual Reality) device. a user wearing a pair of VR goggles visually recognizes overlapped marker images displayed in the 360-degree VR space, and a stationary state is detected when the images for right and left eyes are overlapped, and when the stationary state satisfies a predetermined condition set in advance, one of the plurality of marker images displayed on the display in this state, which is at the center, is set as a marker image for calibration setting, calibration data of the interpupillary distance based on the marker image for calibration setting having been set is acquired, and the acquired calibration data is set as calibration data used for subsequent reproduction of images.
