A user interface, system, method and software for displaying a simulated three-dimensional display of menu options to a user, thereby maximizing use of a display's real estate by presenting all available options at once while at the same time presenting certain options in a more pronounced manner. The system monitors for running applications, polls the running applications for any available options, and displays the options in the simulated three-dimensional format. With this type of dynamic menu, standard means for bringing focus to a selectable target create complexities, and are thus avoided by designing the system's cursor to duplicate the appearance of the selected target's shape, preferably in a smaller size.

An image display system provides a viewer with an experience of three dimensional images by presenting a composite image source. The system includes first and second image sources, a beamcombiner, a lens and a reflective element. The reflective elements reflects the image of the second image source to the beamcombiner. The first and second image sources, the beamcombiner, and the single lens present a foreground image and a background image, with the background image presented at a greater distance from the viewer than the foreground image. The viewer perceives the foreground image and the background image as part of a scene having depth.

A video display for two or three dimensions has a flat liquid-crystal screen which ejects light from the plane at a selectable line. One or, in the case of a 3-D display, several video projectors project a linear image into the plane from an edge. A complete image is written on the screen by addressing the line with appropriate images as it is scanned down the screen. To screen a three-dimensional image, the video projectors, each projecting an image as seen at a slightly different angle, combine to constitute a three-dimensional display which produces a three-dimensional image that is one line high.

The method of presenting concurrent information about the electrical and mechanical activity of the heart using non-invasively obtained electrical and mechanical cardiac activity data from the chest or thorax of a patient comprises the steps of: placing at least three active Laplacian ECG sensors at locations on the chest or thorax of the patient; where each sensor has at least one outer ring element and an inner solid circle element, placing at least one ultrasonic sensor on the thorax where there is no underlying bone structure, only tissue, and utilizing available ultrasound technology to produce two or three-dimensional displays of the moving surface of the heart and making direct measurements of the exact sites of the sensors on the chest surface to determine the position and distance from the center of each sensor to the heart along a line orthogonal to the plane of the sensor and create a virtual heart surface; updating the measurements at a rate to show the movement of the heart's surface; monitoring at each ultrasonic sensor site and each Laplacian ECG sensor site the position and movement of the heart and the passage of depolarization wave-fronts in the vicinity; treating those depolarization wave-fronts as moving dipoles at those sites to create images of their movement on the image of the beating heart's surface; and, displaying the heart's electrical activity on the dynamically changing image of the heart's surface with the goal to display an approximation of the activation sequence on the beating virtual surface of the heart

A three dimensional imaging system is disclosed which includes a three dimensional display (12), three-dimensional calibration equipment (16), and one or more two-dimensional (15) or three dimensional (14) image scanners. The three-dimensional display (12) uses optical pulses (32a-32k) and a non linear optical mixer (18) to display a three-dimensional image (17). The three-dimensional image (17) is generated in voxels of the display volume (28) as the optical mixer (18) sweeps the display volume (28). The three-dimensional calibration equipment (16) uses a hologram projected proximal to a desired object (164) to calibrate optical imaging devices (162a-162c) and to simplify the combination of the images from one or more optical imaging devices (162a-162c) into three-dimensional information. The three-dimensional image scanner (14) employs optical pulses (136, 138) and a non-linear optical mixer (128) to acquire three-dimensional images of a desired object (134). The three-dimensional image scanner (14) captures both the shape and color of a desired object (134).

An image signal composed of sequential frames is input to a 3-dimensional image creating apparatus, frame by frame. A controller (102) designates the presence/absence of reduction, the presence/absence of joining and 2D select. An image converter (101) creates image data in the format designated by the presence/absence of reduction and the presence/absence of joining. A 3D information creator (103) creates 3D information necessary for displaying the image as a 3-dimensional image by formatting the presence/absence of reduction, the presence/absence of joining and 2D select. A multiplexer (104) converts image data and 3D information in a predetermined format and outputs them to the outside. In this way, it is possible to make the image data for 3-dimensional display versatile and select an arbitrary viewpoint image efficiently.

A system, and computer implemented method are provided for interactively displaying three-dimensional structures. Three-dimensional volume data (34) is formed from a series of two-dimensional images (33) representing at least one physical property associated with the three-dimensional structure, such as a body organ having a lumen. A wire frame model of a selected region of interest is generated (38b). The wireframe model is then deformed or reshaped to more accurately represent the region of interest (40b). Vertices of the wire frame model may be grouped into regions having a characteristic indicating abnormal structure, such as a lesion. Finally, the deformed wire frame model may be rendered in an interactive three-dimensional display.

To a multimedia information file including three-dimensional image data, three-dimensional display control information is added that indicates an intended three-dimensional display method for the three-dimensional image data or a data format in which the data is recorded. A three-dimensional image reproduction apparatus performs conversion appropriate for data characteristics derived from the three-dimensional display control information and then provides display. Recorded three-dimensional image data is thus given versatility so that the same three-dimensional image data can be used commonly to different three-dimensional display schemes.

The invention is directed to a method for three-dimensional display in which a plurality of individual image elements ajj are made visible simultaneously in a raster of columns i and lines j, wherein the image elements alphaij reproduce partial information from a plurality of views Ak (k-l . . . n) of a scene/object, and adjacent image elements alphaij radiate light of different wavelengths or wavelength regions. The invention is further directed to arrangements for carrying out the method. In a method of the type described above, wavelength-dependent propagation directions are predetermined for the light radiated from the image elements alphaij. The propagation directions within an observation space in which an observer is situated intersect in a plurality of intersection points which correspond to observation positions. From each observation position, one eye of an observer perceives predominantly partial information of a first selection and the other eye perceives predominantly partial information of a second selection from views Ak (k=l . . . n).

An apparatus and method for controlling the depth of a three-dimensional image. The apparatus includes: a disparity measuring unit which measures the disparity between a left eye image and a right eye image; a physical distance calculating unit which calculates the physical distance between the left eye image and the right eye image based on the measured disparity and the physical characteristics of a display; and a depth controlling unit which controls the depth depending on the calculated physical distance. It is possible to adaptively control the disparity to control the depth when a user uses a stereoscopic three-dimensional display having a different screen size than a display used in a manufacturing environment.

In the three-dimensional display, a two-dimensional display section generates a two-dimensional display image based on an image signal, and a lens array converts the wavefront of the display image light from the two-dimensional display section into a wavefront having a curvature which allows the display image light to focus upon a focal point where an optical path length from an observation point to the focal point is equal to an optical path length from the observation point to a virtual object point, so a viewer can obtain information about an appropriate focal length in addition to information about binocular parallax and a convergence angle. Therefore, consistency between the information about binocular parallax and a convergence angle and the information about an appropriate focal length can be ensured, and a desired stereoscopic image can be perceived without physiological discomfort.

The present invention provides a three-dimensional image display capable of presenting stereoscopic display in a true sense not only for a still image but also for a dynamic image without any need for a dedicated eyeglass or coherent light.

A multiplicity of screen dots (11) formed by LCDs which allows simple changes of the contents of an image are arranged on a three-dimensional display screen (10), and object images formed by the LCDs are projected in a space to form a multiplicity of point light source images (P) that form a three-dimensional image (R) to be displayed. A viewer (Q) can view the same as a stereoscopic image.

A polymer-dispersed liquid crystal based display is embedded inside a lightguide illuminator sheet which provides illumination of the display without the need for a backlight or frontlight. Light from one or more light sources is coupled into the lightguide sheet and is guided within a range of high angles of incidence within the sheet by total internal reflection. The guided light illuminating portions of the display which are in diffusing state is scattered such that some of the light is allowed to escape total internal reflection, providing visibility of the display. Guided light illuminating portions of the display which are in non-diffusing state remains guided within the lightguide illuminator sheet. Combining multiple lightguide embedded displays can be used to provide a three-dimensional display. When a low refractive index cladding is applied to the surfaces of the lightguide embedded display, the display is robust in a dirty environment, and/or can be laminated to adjacent lightguide embedded displays. The use of one or more coupled light sources, such as light emitting diodes, provides color by combining one or more colored light sources or by time-sequentially driving one or more colored light sources. The lightguide illuminator embedded display may further be used as a content dependent active backlight for an LCD display panel to provide improved dynamic contrast.

In a presently preferred embodiment of the invention, a three-dimensional scene is reproduced on a specialized light display which offers full multiviewpoint capability and auto-stereoscopic views. The displayed image is produced using a set of M two-dimensional images of the scene collected at a set of distinct spatial locations. These M two-dimensional images are processed through a specialized mathematical encoding scheme to obtain a set of NxK display-excitation electrical-input signals, where K is the number of pixels in the display, and N<=M is the number of individual light-radiating elements within one pixel. The display is thus comprised of a total of NxK light-radiating elements. Each of the K pixels is adapted for control of their associated radiance patterns. The display is connected for response to the set of NxK display-excitation electrical-input signals. In this manner, the display provides a multiviewpoint and autostereoscopic three-dimensional image associated with the original three-dimensional scene. An alternative embodiment of the invention is utilized to provide efficient storage and display of 3D computer graphics images.

One embodiment of the present invention provides a system that facilitates manipulating a window within a three-dimensional (3D) display model, wherein the window provides a 2D user interface for a 2D application. During operation, the system displays a view into the 3D display model through a two-dimensional (2D) display. Upon receiving a command to manipulate the window within the 3D display model, the system manipulates the window within the 3D display model so that the manipulation is visible within the 2D display.

A matt surface (7) of a display screen (2) is converted to an optically flat surface (11), for example, via an epoxy resin coating (10) or the like which has a refractive index equal to that or the matt surface (7). Alternatively, the matt surface (7) may be removed from the screen (2), and replaced with an optically smooth surface. The matt surface may be a diffusive surface (7) formed on a birefringent film (6) of an LCD screen (2). The display screen (2) is the front screen of a multilevel three-dimensional display comprising layered screens (2, 3), and altering the surface from matt to flat reduces the blurring of displayed images.

One embodiment of the present invention provides a system that facilitates displaying multiple two-dimensional (2D) windows with related content within a three-dimensional (3D) display model. The system starts by receiving a command to display a first window within the 3D display model. In response to the command, the system displays the content of the first window on a first surface of a 3D object. Next, the system receives a command to display a second window within the 3D display model, wherein content of the second window is related to content of the first window. The system then displays content of the second window on a second surface of the 3D object.
