Position information of equipment at an event, such as a ball, one or more players, or other items in a game or sporting event, is used in selecting camera, camera shot type, camera angle, audio signals, and/or other output data for providing a multimedia presentation of the event to a viewer. The position information is used to determine the desired viewer perspective. A network of feedback robotically controlled Pan-Tilt-Zoom (PTZ), manually controlled cameras and stationary cameras work together with interpolation techniques to create a 2D video signal. The position information may also be used to access gaming rules and assist officiating of the event. The position information may be obtained through a transceiver(s), accelerometer(s), transponder(s), and/or RADAR detectable element(s) fitted into the ball, apparel or equipment of players, the players themselves, or other playing equipment associated with the game or sporting event. Other positioning methods that can be used include infrared video-based tracking systems, SONAR positioning system(s), LIDAR positioning systems, and digital signal processing (DSP) image processing techniques such as triangulation.

Methods, apparatus, and computer programs for controlling a view of a virtual scene with a portable device are presented. In one method, a signal is received and the portable device is synchronized to make the location of the portable device a reference point in a three-dimensional (3D) space. A virtual scene, which includes virtual reality elements, is generated in the 3D space around the reference point. Further, the method determines the current position in the 3D space of the portable device with respect to the reference point and creates a view of the virtual scene. The view represents the virtual scene as seen from the current position of the portable device and with a viewing angle based on the current position of the portable device. Additionally, the created view is displayed in the portable device, and the view of the virtual scene is changed as the portable device is moved by the user within the 3D space. In another method, multiple players shared the virtual reality and interact among each other view the objects in the virtual reality.

An adaptive underwater camera housing and control interface for use with a broad range of camera brands and models. The camera housing is preferably formed of front and rear housing sections that are molded of clear transparent plastic and arranged to be moved between an open position for mounting a camera within the housing and a closed position in which the housing provides a watertight enclosure for protecting and communicating with a camera. Residing in the housing are a controller and communications interface by which a camera can be operated from outside the housing. Magnetic signals are preferably passed to the controller by external signal buttons operated by the user. The external signal buttons do not penetrate the interior surfaces of the housing thereby enhancing its water tightness. The housing is provided with a truncated hemispherical lens through which a camera views scenes to be photographed to reduce distortion and not foreshorten viewing angle and a flat window and diffuser for providing controlled artificial illumination to a scene.

A method and system for automated production of stereoscopic and animated images and hardcopies can utilize a light-sensitive lenticular material employing a conventional or non-conventional photographic emulsion or an instant-developing material. An automated printer can produce autostereoscopic and animated hardcopies in multiple formats from digital and non-digital sources, including single images, stereopairs, and multiple-image sets of negatives, transparencies, or prints. The printer, which includes a projection device and a material plate that can rotate around two perpendicular axes, can utilize software to automate viewing angle calculation, printer control, multiple-image alignment, distortion correction, and image processing and conversion. A digital camera can capture stereoscopic and animated images and record them digitally or on photographic film. A non-digital camera can record stereoscopic and animated images directly onto light-sensitive lenticular material employing a conventional or non-conventional photographic emulsion or an instant-developing material. The printer and cameras can utilize autostereoscopic monitors to preview parallax.

There is disclosed a lightweight and small liquid crystal display which achieves low power consumption and in which the optical anisotropy of the liquid crystal material is compensated for in order to enhance the viewing angle characteristics and the response speed of the liquid crystal material. Display electrodes and a common electrode are formed on one of the substrates. The orientation of the liquid crystal material is of the HAN (hybrid alignment nematic) type. This compensates for the optical anisotropy of the liquid crystal material and improves the response speed.

An enhanced electroluminescent sign containing a volumetric, anisotropic scattering element to control the angular spread of light from the sign and the spatial luminance uniformity of the sign. The anisotropic scattering element contains one or more regions of asymmetrically-shaped light scattering particles. The angular spread of light leaving a sign from a light emitting source can be efficiently controlled by using a thin, low cost, volumetric, anisotropic scattering elements to angularly and spatially distribute light, permitting the reduction in number of light sources, a reduction in power requirements, or a more tailored viewing angle.

To provide a camera built-in type rearview mirror device with illumination, wherein rigidity of the mirror housing can be raised, the camera main body part can photo a clear picture by extensive photographing feasible viewing angle through a transparent cover, and built-in of the camera module is simple. Mirror housing 2 includes concave part 2C formed in an opening manner downwardly which is arranged in the vicinity of photographing window 2B where lens 5B of the camera main body part 5A is faced, and capable of accommodating an illumination light source. For this reason, opening area of the photographing window 2B is decreased. Also, the circumference of the photographing window 2B is reinforced by the cross-sectional box type form of the concave part 2C. Especially a bulge part with circular curved section is formed so that the lens of the camera main body part may rush in, to thereby decrease the opening area of the photographing window further. Then rigidity of the mirror housing 2 is further raised.

A visual display screen (100′) such as an LCD screen is provided with a display area (30) for displaying an image. The display area (30) extends as far as an optically inactive region (60), containing device drivers, at the edge of the screen.

A cover plate assembly (40) overlays the display area (30). The cover plate assembly is laminar and an upper translucent plastics layer (520) thereof is planar over the display area (30) but is curved at the edge to provide a lens there. Thus, the image in the display area viewed through the cover plate assembly (40) appears to be shifted to the edge of the screen (100′) so that the optically inactive region (60) becomes invisible. Two screens can be abutted adjacent each other with no visible join using this technique. Compression of the image at the edge compensates for edge distortion by the lens. Repeating of the image either side of the join between two screens increases the viewing angle beyond which the join appears.

Three objective lenses (11) having optical axes L oriented to different directions are mounted on a head portion (10) of an endoscope device. The objective lens (11) has a predetermined view angle θ centered by the optical axes L. Each objective lens (11) is disposed so as to have the peripheral portions of its viewing field overlap with the peripheral portions of the viewing fields of adjoining other objective lenses (11). Hence, the three objective lenses (11) causes the head portion (10) as a whole to have a view angle φ extending over a wider range than the view angle θ of the objective lens (11) with no discontinuation. Each optical image of a testing target part captured within this view angle φ is imaged by an imaging element.
