    摘要: An apparatus and method for processing pixel data is presented that includes an image forming apparatus that includes an image forming module coupled to a data control module that comprises a plurality of memory units, wherein each of the memory units stores a corresponding portion of pixel data of an image. The data control module writes out portions of pixel data stored in corresponding memory units to the image forming module and dynamically associates each memory unit with a further portion of pixel data after its corresponding portion of pixel data has been written out.

    摘要: An apparatus and method for processing pixel data is presented that includes a plurality of image forming modules coupled to a data control module. The data control module includes a plurality of memory units. Each memory unit can store a portion of an image. The data control module receives a first signal and a second signal and selects at least one of the plurality of image forming modules to send the image portions stored in the plurality of memory units based on a timing relationship between a first image alignment event on the first signal and a second image alignment event on the second signal.

    摘要: An imaging device with an improved controller is disclosed wherein the controller eliminates duplicated circuitry and provides multiuser circuitry that efficiently replaces multiple dedicated circuit blocks. In one aspect, duplicated same-function circuit blocks are replaced with a switch controlled by an alignment control signal to operate as a multiplexer or demultiplexer. In another aspect, multiple different-function circuit blocks which generally have no temporal overlap of their active operation are replaced with a programmable logic device that is reconfigured dynamically to perform some subset of the different functions on an as-needed basis.

    摘要: Systems and methods are provided for reducing data size of at least one bitmap image using a look-up table, wherein the look-up table stores information correlating a plurality of compression ratios to a set of compression parameters and wherein the bitmap image comprises a plurality of image components, each image component associated with a distinct color plane. The plurality of color planes may be ranked using a dominance rank, wherein the dominance rank for a color plane is based on image component data associated with the color plane. At least one compression ratio may be associated with each color plane based on the dominance rank associated with the color plane. At least one image component may be compressed according to the compression ratio associated with the color plane corresponding to the image component using compression parameters obtained from the look-up table. The compression ratio may be iteratively adjusted, until the total data size of the plurality of image components is below a data size threshold.

    摘要: Systems in accordance with the presently claimed invention use input data to create an output pulse that is a fraction of the width of a pulse of a pixel clock. The fraction of the width of a pulse of the pixel clock can be used to create a fraction of a pixel. Justification data may also be used to justify the fraction of the pixel. The presently claimed invention maintains a static pixel justification lookup table that can be used to determine the justification for each pixel.

    摘要: Apparatus, systems, and methods presented herein allow for the alignment of images. In some embodiments, a plurality of PWM modules each receive input data and corresponding input phase-shifted clock signals. In some embodiments, each PWM module generates an output phase-shifted PWM signal based on the input data and its corresponding input phase-shifted clock signal. In some embodiments, a selector selects one of the output phase-shifted PWM signal based on timing relationships between an event signal and the phase-shifted clock signals.
