A display device can generate a stereoscopic image, a depth level sensor measures a distance to an object, and a control section displays a view on the display device according to the depth level sensor. A depth level adjustment mechanism adjusts at least one of a region width and a region position of a measurement region of the depth level sensor.

An object of the present invention is to provide an I/O device, an I/O program, and an I/O method which enable easy manipulation. Another object of the present invention is to provide an I/O device, an I/O program, and an I/O method which enable easy manipulation on the basis of ergonomics. The I/O device includes a display device that can generate a stereoscopic image, a depth level sensor that measures a distance to an object, and a control unit that performs display on the display device in accordance with the depth level sensor. A detection region of the depth level sensor has a width in the depth level direction of the depth level sensor, and is composed of a curved measurement region, such that the radius of curvature on the far side in the depth level direction of the depth level sensor is different from the radius of curvature on the near side in the depth level direction of the depth level sensor.

Disclosed is a system for synchronizing 3D image multiple screens in real-time. The system comprises: an operation server for playing back 3D content; a plurality of displays displaying the whole, each display displaying just a part of the 3D content; a plurality of rendering clients each rendering just a part of the 3D content to output to a corresponding display; and a synchronization integration control server for controlling so that the plurality of rendering clients can render while synchronized.

An autostereoscopic display includes a plurality of projectors and a screen. Each of the projectors is configured to provide a corresponding lamp image unit. Each of the lamp image units includes array of lamp images actuated in time sequence and projecting to different directions. The screen has an image plane and includes a first micro-lens array and a second micro-lens array.
