    摘要: An m×n pixel cell may be obtained from an input image, each of the pixels having a respective color value. A characterization of the cell may be determined, including determining a lowest color value and a highest color value of the pixels cell. A difference between the highest color value and the lowest color value may be calculated. If the difference is less than or equal to a threshold difference, an output color value inclusively between the highest color value and the lowest color value may be selected, and a first representation of the output color value may be written to an output medium. If the difference is greater than the threshold difference, multiple output color values may be selected, and a second representation of the multiple output color values may be written to the output medium.

    摘要: A system and method for trapping in electrophotographic color printing and related technologies for printing or display in which the final image is an overlay of multiple components subject to alignment errors. Trapping is based on the cyan (C), magenta (M), and black (K) planes. There are four steps as follows: detect object edges on each of the four color planes; detect coincident and opposing edge transitions on each pair of planes (CM, CK, and KM); determine which plane to trap, i.e., to extend object across edge; and generate trap on that plane using a simple trap generation rule and a single trap generation rule.

    摘要: A system and method of decoupling timing in a high speed bus system. A master/slave translator is coupled between a master device and a slave device. A pseudo slave of the master/slave translator responds to the master in a first timing protocol. A pseudo master of the master/slave translator masters the slave devices under a different timing protocol. The master/slave translator causes the master to believe its communications with the slave device are occurring under the first protocol.

    摘要: A network system is described having multiple network components. The multiple network components include at least one central office (CO) and at least one customer premise equipment (CPE) coupled to the at least one CO. One of either the CO or CPE captures a clock, generates a reference clock, and sends the clock to the remainder of the multiple network components to ensure synchronous operation.
