Abstract: Three-dimensional color images are produced by combining the red image plane from a left color camera and the blue and green image planes from a right color camera. Techniques for compensating for over or underexposure in a particular image plane are deployed as well as techniques for minimizing subjective disturbance when viewing relatively pure color regions of a 3-dimensional image and for transmission of 3-dimensional color television images to users.

Abstract: A video camera is positioned stereotactically to view a surgical opening in a patient and provide data related to stereotactic space and is stereotactically representative of a current actual view, which data is processed and displayed as a current actual image along with a reference image that is computer generated from graphics image data stored on the patient. The two images appear in a display variously, for ease of comparison and are coordinated by stereotactically tracking the camera to maintain position and orientation. A composite camera structure incorporates a surgical microscope and stereoscopic viewing along with light tracking coordination. Displays included side-by-side and overlapped.

Abstract: A method for generating images that appear as complex three-dimensional surfaces when viewed using a stereoscopic viewing system, using only a minimum amount of data to define the images. The stereo contours of a complex three-dimensional surface are drawn using a three-dimensional computer drawing system and three-axis input device. The drawing is viewed with a stereoscopic viewing system using, e.g., a CRT where the left and right eye images are time multiplexed in sequential fields and liquid crystal shutter glasses synchronized with the CRT display. Simply by drawing closed loops in space, filling the closed loops with color, and drawing a minimum number of other stereo contours, an image is created which appears to define a complex three-dimensional surface. The image creates a mental perception of a complete solid object by providing to the observer's eye only the minimum cues required by the brain to create stereo objects with complex surfaces, taking advantage of the stage of human neural processing in which the images the eye sees are coded into similar stereo cues. The normal image processing of the brain is in effect substituted for the complex mathematical processing of prior systems to create objects perceived as having three-dimensional volume and surfaces. Therefore, the tedious design and computations required by present systems to produce a full computer graphics description of the object are eliminated, thereby substantially reducing the time required to draw three-dimensional objects as well as the processing requirements where the images are processed by computers, thus making it possible for artists to create three-dimensional images as simply and intuitively as two-dimensional images have historically been created on two-dimensional surfaces.

Abstract translation: 一种用于使用仅使用最少量的数据来定义图像的立体观看系统来生成作为复杂三维表面的图像的方法。 使用三维计算机绘图系统和三轴输入装置绘制复杂三维表面的立体轮廓。 使用例如CRT，其中左眼图像和右眼图像在顺序场中进行时间多路复用并且与CRT显示器同步的液晶快门眼镜，使用立体观察系统观看该图。 简单地通过在空间中绘制闭环，用颜色填充闭环，并绘制最小数量的其他立体轮廓，创建出似乎定义复杂三维表面的图像。 该图像通过向观察者的眼睛提供大脑所需的最小提示，以创建具有复杂表面的立体物体，从而产生对完整固体物体的精神感知，利用眼睛看到的图像的人类神经处理的阶段 编码成类似的立体声提示。 大脑的正常图像处理实际上取代了现有系统的复杂数学处理，以创建被感知为具有三维体积和表面的对象。 因此，消除了当前系统产生对象的全部计算机图形描述所需的繁琐的设计和计算，从而大大减少了绘制三维对象所需的时间以及图像由计算机处理的处理要求， 因此使得艺术家可以简单直观地创建三维图像，因为二维图像历史上在二维表面上被创建。

Abstract: An electro-optical backlighting panel construction for use in portable computer-based systems having direct and projection viewing modes of operation. In the illustrative embodiments of the present invention, the electro-optical backlighting panel is integrated with a LCD display panel, a micropolarization panel, and a touch-screen writing panel to provide several different types of portable computer-based systems including, for example, a portable notebook computer, a computer-driven image display device, and a portable pen-computing device. In general, each of these computer-based systems are capable of selectively displaying color video images on an actively driven display surface, or projecting such video images onto a wall surface or projection screen. These computer-based systems can be easily reconfigured for projection viewing without any sort of physical modification to the LCD display panel assembly. If desired, the these computer-based systems can be used to directly view "spatially-multiplexed" images of 3-D objects or imagery during the direct viewing mode, and when desired these spatially-multiplexed images can be projected onto a wall surface or projection screen during the projection viewing mode. When the spatially-multiplexed images are viewed through electrically-passive polarized glasses, the 3-D object is perceived with stereoscopic depth sensation in either mode of viewing. A portable light projection accessory device is provided for use with the portable computer-based systems of the present invention. In the illustrative embodiments, the portable light projection device has first and second housing portions that are interconnected by a foldable structure that permits the first and second housing portions to be selectively reconfigured for simple trouble-free use during the projection viewing mode of operation, and for compact storage during the direct viewing mode of operation.

Abstract: A stereoscopically displayed three dimensional medical imaging system derives image data from a tomographic imaging apparatus and reconstructs the image data into a three dimensional model and displays right and left stereoscopic three dimensional image components of the model on corresponding right and left video display devices of a stereoscopic viewing unit. The system includes a system computer interfaced to the imaging apparatus and a pair of image channels, each including a three dimensional display processor, and a video display device. The three dimensional display processors receive polygon image data, reconstruct it into a three dimensional form, and select image data representing a three dimensional view from a selected perspective. The system computer generates the polygon image data and controls the display processors to present mutually angularly displaced views of the same three dimensional image to form the stereoscopic image components.
