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.

摘要： A workstation with multiple, functionally related displays clustered under and controlled by a common transparent overlay control device. The position of a hand-held stylus is sensed by the overlay control device and is used as a system input to control system operations, system communications and input, manipulation and editing of images displayed on the displays. Control of certain workstation operations is achieved by directing the stylus towards function symbols which are affixed to the overlay surface. Actuators or other adjustment mechanisms are provided for adjustment of the height and pitch of the workstation for the comfort of the operator. Further, the workstation provides integrated data audio communication over ordinary narrow-band telephone lines or high speed data lines with other linked workstations.

摘要： An image processing apparatus coupling at least two image processing systems connected to a network. The network couples image information to each system, and each system displays at least one image. Each system includes a communication unit and a control unit. The communication unit couples information to and receives information from the network. The control unit includes a central processing unit (CPU) and a partitioned memory space, including, both common and personal memory. The personal memory of each system contains one or more personal images that can be viewed only by the respective system, wherein each system is controlled to access only its respective personal memory. Under control of the CPUs in the respective systems, a common image is coupled to each system over the network and commonly displayed on each system. While the common image is commonly displayed on each system, it is edited by the first image processing system.

摘要： An improved high resolution method and apparatus are described for sensing and determining the spatial coordinates of a movable object with respect to a energized conductive surface. The coordinates of the object are precisely measured 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 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. The system described improves the precision and accuracy of the location of the selected point and hence the precision and accuracy of the spatial coordinates calculated by the system for display. The improvement in system performance is the result of innovations in fundamental design concepts utilized throughout the system.

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.
