摘要： A system for sensing the spatial position of a moveable object with respect to an energized conductive surface whereby the spatial coordinates of the object are determined. The system provides a means of accurately measuring the coordinates of the object with respect to a two-dimensional coordinate system independent of the third orthogonal dimension, thereby avoiding significant measurement errors due to variations of the object's position in the third orthogonal dimension. The system also ascertains the coordinate position of the object in this third dimension, which can then be utilized as an independent control variable in the system. Further, the system can accommodate a number of energized conductive surfaces over which the object may be positioned and can determine the spatial coordinates of the object with respect to any such surface. In general, the system of the present invention can ascertain the generalized n-tuple position vector of the object with respect to each of a plurality of generalized, energized conductive surfaces. In any of the foregoing forms, the energized conductive surfaces can be transparent.

摘要： Method and apparatus for the selective scaling, such as magnification and reduction, of video images stored as collections of image pels in a video memory. A lookup table is provided for determination of the values of the scaled image pels. A framing matrix of unscaled image pels is established for each scaled image pel. The framing matrix for the scaled image pels determines the outputs read out of the lookup table, and derivatively, determines the values of the scaled image pels. The scaled image pels are stored in the video memory for subsequent display or processing.

摘要： A method and apparatus for compressing digital image data using interlocking digitate geometric sub-areas. The digital picture elements, or PELs, representing the image are divided into interlocking digitate sub-areas, which, in the preferred embodiment, are of substantially the same size and shape. Data compression is achieved for the PELs within a sub-area by first sorting the values of the PELs within the sub-area by magnitude. Depending upon the magnitudes of the PELs in the sub-area relative to the magnitudes of the other PELs in the sub-area, the PELs in the sub-area are either coded solid tone, with each PEL in the sub-area having the same tone, or coded bi-tonal, with each PEL in the sub-area having either one of two tones. A smoothing process is utilized to reduce undesireable effects at the edges of the sub-area.

摘要： The present invention provides means and methods for generating high resolution color computer generated graphic elements, such as lines, circles and curves, using a modified color-under coding system. A portion of the original luminance grey scale is reassigned or reallocated for substitution with data for high resolution graphic elements. High resolution graphic data are introduced by a user-operated input device via a control device such as a computer. The input luminance signal is digitally limited and stored in video random access memory (VRAM). A level detector detects the Y signal level to determine the presence of certain Y signal levels. Memory look-up tables provide appropriate user-determined substitute values for the Y, I and Q data values where certain, preselected Y signal levels are detected.

摘要： An image retrieval system and method are provided for retrieving and displaying images of the plurality of images stored in the system. Images are grouped into collections of images, or documents. Representative images indicative of the representative images include representations of third, orthogonal or depth dimensions indicative of the number of images in the image groups. With a position indicating device, the user selects for display an image from an image group by indicating a position along the depth dimension of the representative image at a location corresponding to the relative location of the image in the image group. The image then is retrieved and displayed. Once the image is displayed, means are provided for sequential retrieval and display of images, forwards or backwards, through the images in the selected image group.

摘要： An improved apparatus for rapidly compressing, expanding, and displaying broad band information which is transmitted over a narrow band communications channel. In the preferred embodiment, a video image is cyclically assembled in low resolution and high resolution phases from digitized data representing gray level intensity for individual pixels which have been grouped into pixel. During the initial cycle of the low resolution phase, a representative sample of cell intensity values is transmitted by a sending station to a receiving station according to a video compression routine. The receiving station then uses a video expansion routine to calculate an intensity value for those pixels whose intensity values were not transmitted and displays an initial image. This image is refined during subsequent low-resolution cycles by additional transmissions from the sending station which replace the calculated cell intensity values with an actual or better approximation value for that pixel. During the high resolution phase, an error determination routine or external input from a viewer selects those pixels containing the greatest deviation in intensity levels from the input video image. The error compression and expansion routines substitute a plurality of individual pixel intensity values for previously calculated intensity values. The present invention also discloses an apparatus for allowing color capable stations to send or receive color transmissions while retaining the capability to interact with noncolor stations. Color data is compressed and interleaved with black and white data by a color capable sending station and subsequently separated and expanded by a color capable receiving station.
