Abstract: The image display system includes a first image producer producing a first left-eye display image using a left-eye original image that is a left-eye captured image or a left-eye processed image produced therefrom, and producing a first right-eye display image using a right-eye original image that is a right-eye captured image or a right-eye processed image produced therefrom. A first image display unit allows left and right eyes of a viewer to view the first left-eye and right-eye display images. The first image producer produces the first left-eye and right-eye display images each corresponding to an image of a partial area of the original image. A second image producer produces, using at least one of the left-eye and right-eye original images, a second display image corresponding to an image of an area including the above partial area and being wider than that partial area.

To do this, the wearable display apparatus incorporating display units for displaying videos to be presented to an observer includes main cameras for capturing images, to be displayed on the display units, in an eye direction of the observer when the display apparatus is worn, and sub cameras having angles of view wider than those of the main cameras to include fields of view of the main cameras.

Abstract: A head-mounted device to be worn on a user's head includes a first pressing member to press, for example, an occipital region, a second pressing member to press, for example, a parietal region, and first and second linear members connected to the first and second pressing members respectively. The first and second linear members are guided so that a change in lengths of the first and second linear members causes the first and second pressing members to move in the first and second directions respectively. An adjustment unit to adjust the lengths of the first and second linear members includes first and second wind-up units connected to a rotational operation member and to wind up the first and second linear members respectively.

Abstract: The invention provides a head mounted image-sensing display device including a pair of image-sensing units (18R, 18L) that stereoscopically capture a physical space and output a pair of stereoscopic images, and display units (13R, 13L) for displaying images for the right eye and images for the left eye. Image sensing parameters that are previously measured for the image-sensing units are stored in image sensing parameter storage units (26R, 26L). As a result, a difference in parallax between captured images of a physical space and images of a virtual object is reduced.

Abstract: To shield a frame area 203b, a frame-like shield member 501 is superimposed over an LCD 203 while being separated from the LCD 203 by a distance L. The distance L satisfies L<2×(B?A)×f/D where f is a focal length of an optical system, D is a human pupil diameter determined statistically in advance, B is a width of the frame area, and A is a value determined statistically in advance as a width which will not be able to be shielded on a side of the frame area to be shielded by a side of the shield member.

Abstract: A winding device includes a winding member that rotates to wind a flexible member therearound, a first rotating member that is rotatable, a second rotating member that is rotatable coaxially with the winding member and has a smaller resistance to rotation in a predetermined direction than that to rotation in a direction opposite the predetermined direction, and an engaging member. When the first rotating member is subjected to a first torque, the engaging member brings the winding member, the first rotating member, and the second rotating member into engagement with one another, so that the winding member becomes rotatable together with the first rotating member in the predetermined direction. When the first rotating member is subjected to a second torque in a direction opposite that of the first torque, the engaging member releases the engagement, so that the winding member becomes rotatable in the direction opposite the predetermined direction.
