    Abstract: The present invention relates to a digital display plotter for plotting images on a digital display device (18). A cursive imagery generator (12) generates cursive inputs at a plurality of respective update phases during a refresh period of the display device. A control for the display device activates selected pixels of the digital display device in response to respective said cursive inputs, activation being controlled subsequent to each update phase during a refresh period. An input store (14, 16) associates each cursive input with an update phase that the cursive input was generated during a refresh period. The control is responsive to the input store and configured to deactivate the selected pixels activated in response to each cursive input dependent on the associated update phase of each cursive input.

    Abstract: Disclosed are techniques for determining in a lattice a set of cells of the lattice that are intersected by a line endpoints. The techniques employ orders 1.. n of runs of lattice cells to make the determination and are usable with lines whose endpoints have coordinates that may be any real number. The techniques include an initialization that derives an error term with a real number value and a structural parameter with a real number value for order 1 using the values of the coordinates of the end points and then determines the error terms and structural parameters for each order i belonging to the orders 2.. n using the error term and structural parameter for order i - 1. When the first run of any orders 1.. n is truncated, the initialization also adds the cells belonging to the truncated run to the set. When the initialization is finished, the remaining cells belonging to the set are determined using full runs of order n . In either the initialization or the determination using full runs, the techniques terminate when a cell is added to the set that includes the x and y coordinates of the line's endpoints. Also included is a technique for determining whether the cell that includes the x and y coordinates of the start of the line is to be included in the set of cells prior to the initialization. When the cell is so included, the relationship between the x and y coordinates of the start of the line and the x and y coordinates of the lower left-hand corner of the cell are used together with the slope of the line to obtain an error term which is used to determine the location of the next cell belonging to the set. Disclosed applications of the technique include making pixel representations of lines and determining locations in a plane that is represented by a lattice that are intersected by particular lines.

    Abstract: Display apparatus, and methods for displaying images, e.g., text, on gray scale and color monitors (2400) are described. Gray scale displays implemented in accordance with the present invention include displays having a resolution in a first dimension, e.g. the horizontal dimension, which is several times the resolution in a second dimension, e.g., the vertical dimension. Various other displays (2400) of the present invention are capable of operating as both gray scale and color display devices. In one such display, the color filter used to implement a color portion of the display is omitted from another, e.g., gray scale portion of the same display. In such an embodiment, text, e.g., captions, are displayed using the gray scale portion of the display while color images, e.g., graphics, are displayed on the color portion of the display. In another display of the present invention, a color filter (2401) with filter cells (2410, 2411, 2412) that can be switched between a color and a clear mode of operation are employed. When images., e.g., text, are to be displayed as gray scale images, the filter cells (2410, 2411, 2412), corresponding to the portion of the display (2400) to be used to display the gray scale images, are switched to the clear mode of operation. In such an embodiment, the remaining portion or portions of the display (2400) may be used to display color images. Methods and apparatus for reducing and/or eliminating color distortions in images resulting from treating pixel subcomponents as independent luminous intensity sources are also described.

    Abstract: An original binary image is converted to a weighted multi-valued image by a pixel converter. The original binary image is converted in such a manner that its pixels are reversed and shifted upward by one dot by a shift-up/reverse circuit to form an upward shifted reverse image, they are reversed and shifted downward by one dot by a shift-down/reverse circuit to form a downward shifted reverse image, they are reversed and shifted to the right by one dot by a shift-right/reverse circuit to form a rightward shifted reverse image, and they are reversed and shifted to the left by one dot by a shift-left/reverse circuit to form a leftward shifted reverse image. A halftoning circuit processes the shifted reverse images by subtraction to synthesize a halftone image.

    Abstract: Line drawing techniques that employ runs or runs of runs of pixels to draw the line compute line structure information that they use to determine the sequence of runs in the line. This line structure information may be used in other ways to enhance the line drawing operation. One of the ways is to use the line structure information to compute the positions of a plurality of the runs and then draw the runs in parallel. Another way is to use the line structure information to determine properties of sets of cells that include not only cells of the run, but additional cells that are affected by the presence of the cells of the run. One example of such sets of cells is the cells of the run plus anti-aliasing cells. The line structure information can be used to determine the location and size of a set of cells and the intensities of the anti-aliasing cells. Another example of such sets of cells are cells that are written together in a single memory operation. The sets of cells may be drawn in parallel in the same fashion as the runs.

    Abstract: Disclosed are techniques for determining in a lattice a set of cells of the lattice that are intersected by a line endpoints. The techniques employ orders 1..n of runs of lattice cells to make the determination and are usable with lines whose endpoints have coordinates that may be any real number. The techniques include an initialization that derives an error term with a real number value and a structural parameter with a real number value for order 1 using the values of the coordinates of the end points and then determines the error terms and structural parameters for each order i belonging to the orders 2..n using the error term and structural parameter for order i - 1. When the first run of any orders 1..n is truncated, the initialization also adds the cells belonging to the truncated run to the set. When the initialization is finished, the remaining cells belonging to the set are determined using full runs of order n. In either the initialization or the determination using full runs, the techniques terminate when a cell is added to the set that includes the x and y coordinates of the line's endpoints. Also included is a technique for determining whether the cell that includes the x and y coordinates of the start of the line is to be included in the set of cells prior to the initialization.
