    摘要： A method for matching hardcopy colors to display colors for registered-dot ink-jet copiers. Video RGB (red-green-blue) is converted into chromaticity coordinates in XYZ color space. An explicit solution is achieved by defining a new MSW color space which restricts the hardcopy colors to some percentage of one of the binary mixtures (M) of inks, some percentage of one of the single (S) inks, and some percentage of paper white (W). The color data in XYZ space is converted to MSW space and unreachable display colors are mapped into reachable hardcopy colors. Correction for hardcopy non-linearities is accomplished by using coverage ratios to correct for color shifts due to interaction among the inks. The MSW values are then converted to CMY (cyan-magenta-yellow) values which are processed in accordance with an appropriate dithering algorithm for conversion into dots for printing on paper.

    摘要： A block diagram editor system and method is implemented in a computer workstation that includes a CRT and a mouse, graphics and windowing software, and an external communications interface for test instruments. The computer is programmed for constructing, interconnecting and displaying block diagrams of functional elements on the CRT. From prestored routines for each functional element, the software assembles and executes a program that emulates the functional operations of each element and transfers data from output from each element in turn to an input of a succeeding block, as determined by the block diagram configuration. The block functions include signal generating and analysis functions, and functions for control of various types of test instruments, which can be interactively controlled through the CRT and mouse. The computer converts desired outputs of the instruments into control settings and receives, analyzes and displays data from the instruments. Blocks can also be grouped into macroblocks.
