It is possible to view stereoscopic images by performing a “binocular VR display” using the left eye VR image and the right eye VR image, which have parallax with respect to each other. In any VR display, for example, when a user wears a display device such as a head-mounted display (HMD), the image is displayed in a visual field range corresponding to the direction in which the user's face is facing. For example, assume that at a given point in time, a VR image displays a visual field range centered at 0 degrees in the left-right direction (a specific heading, e.g., north) and 90 degrees in the up-down direction (90 degrees from the zenith, i.e., horizontal). If the attitude of the display device is flipped front-to-back from this state (e.g., the display surface is changed from facing south to facing north), the display range is changed to an image of a visual field range centered at 180 degrees in the left-right direction (the opposite heading, e.g., south) and 90 degrees in the up-down direction, of the same VR image. In other words, when the user turns their face from north to south (i.e., turns around) while wearing the HMD, the image displayed in the HMD is also changed from an image of the north to an image of the south.
Note that the VR image shot using the binocular lens unit 300 of the present embodiment is a VR180 format image of a range of substantially 180 degrees in the front, and there is no image of a range of substantially 180 degrees in the rear. If such a VR180 format image is displayed in VR and the attitude of the display device is changed to a side where the image is not present, a blank region, for example, is displayed.
