Abstract: The invention is directed to a computer implemented system and apparatus for transforming objects in a first data model (source design objects) to objects in a second data model (target design objects) and synchronizing the two data models. The result of the transformation is that at least one of the target design objects is associated with a corresponding source design object. The system associates a unique identifier with each of the target design objects and source design objects, the unique identifier being associated with each map associated with each design object.

Abstract: An apparatus and method are provided for encoding and decoding video signals on a conventional magnetic recording medium in a manner whereby the decoded video signal includes an improved chrominance characteristic. The improved chrominance characteristic is provided by encoding the conventional luminance and chrominance information signals on a first track of the information recording medium for the odd alternate fields and a modified luminance information signal and a select separate color component signal on a second track of the information recording medium. The signal recorded on the first track of the recording medium may be decoded in a conventional manner to provide video signals of limited chrominance video bandwidth or, alternatively, both tracks of the recording medium may be decoded in the manner of this invention to provide an improved chrominance characteristic video signal.

Abstract: An electronic imaging camera is provided with a substantially expanded dynamic exposure range by implementing two succeeding exposure intervals under conditions where the exposure defining parameters are substantially different and thereafter selectively choosing between the electronic information signals sensed during the two succeeding exposure intervals to provide an output signal from which a visible image of the subject may be reconstructed thereafter.

Abstract: Image sensing and processing apparatus for use in an image facsimile system in which a subject is sensed in its primary red, green and blue colors as well as its complementary cyan, magenta and yellow colors to provide full color correction or enhancement as a function of color matrixing each primary color with its respective complementary color.

Abstract: Image sensing and processing apparatus in which the different colors of a subject are sensed to provide a high resolution electrical color separation signal and a low resolution electrical color separation signal. An enhanced high resolution electrical color separation signal is thereafter provided as a function of the color matrixing of the low resolution electrical color separation signals with the high resolution electrical color separation signals.

Abstract: An electronic camera for providing a photographic quality still print includes a viewfinder display in which the scene to be photographed may be viewed for composition at a standard television transfer frame rate without the provision of additional buffer memories. The electronic camera comprises an integral charge coupled device (CCD) sensing configuration which operates to sense the image to be recorded in a preview mode of operation and to provide a real time digital buffer memory during a succeeding review mode of operation in order to display the recorded scene in the viewfinder at a standard television frame transfer rate.

Abstract: A high ratio multilaced raster scan system for obscuring the blank spaces between the raster lines on a CRT when making a photograph or hard copy from the screen of the CRT utilizes a selectively varied DC bias voltage to vertically offset in a select sequence succeeding pulses in the vertical ramp pulse train signal which controls the vertical sweep position of the electron beam of the CRT to thereby provide a corresponding sequence of parallel interlaced raster lines vertically offset with respect to each other. The system is calibrated in a simple manner by utilizing an alternating DC bias voltage to vertically offset alternate pulses in the vertical ramp pulse train signal and thereby enable the user to calibrate the average DC level of the selectively varied DC bias voltage by aligning the raster lines of the first and second fields.

Abstract: In a system for exposing a photosensitive material to a video frame represented by a video signal, the image to be photographed is horizontally scanned by a line scanner and the horizontal line scan is incrementally advanced across the video frame in correspondence with the incremental advancement of an exposing focused line across the photosensitive material in order to fully expose the photosensitive material, one line at a time, to the image being scanned by the line scanner.

Abstract: A hard copy of a video frame represented by periodic video signals is obtained by dividing the range of amplitude of the video signals into N levels, converting the video signals into N two-level brightness distributions on the screen of a monochromatic CRT under the condition that a pixel in the ith distribution has the upper of two levels only if the level of the video signal representing the corresponding pixel in the frame exceeds the ith level, and exposing a photosensitive sheet to light from the screen. Thus, each pixel on the sheet is exposed to light of predetermined brightness for a period of time functionally dependent on the level of the video signal represented by the corresponding pixel in the frame.
