    摘要: The video data is parallel processed allowing for extremely fast video processing or a greatly reduced clock requirement for the video processing circuit. In operation, each video channel reads from main memory. This allows each video channel to track the laser directly. The Parallel video processor receives non-columnar pixel data, such as rows. The videoprocessor may support printers of any width without significantly increasing the size of the system.

    摘要: A system includes a first memory portion storing image data and a second memory portion storing a lookup table having image resolution conversion data. Conversion logic is configured to access the image resolution conversion data and convert the image data, which has a first resolution, to print data, which has a second resolution. The second resolution has a lower pixel count than the first resolution. The second resolution has a higher bit per pixel ratio that the first resolution.

    摘要: A method for memory write-back provides a memory access controller and then generates a write-back pattern in the memory access controller. The write-back pattern is then written back into a memory starting at a predetermined address location and continuing for a predetermined length of the addressing space of the memory.

    摘要: A scanning system is adapted to scan an image beam across a photoconductive surface. The scanning system includes an oscillating mirror and is operable to generate an image beam and to reflect the image beam off the oscillating mirror to bidirectionally scan the image beam across the photoconductive surface and thereby discharge regions on the surface. The system is further operable to dynamically scale an intensity of the image beam as a function of a position of the image beam on the photoconductive surface.

    摘要: A laser scanning assembly generates a laser beam and scans the laser beam through a plurality of scan lines to form desired dots. Each scan line is positioned to overlap an adjacent scan line and each dot includes a plurality of segments. The scanning assembly scans the laser beam through multiple scan lines to fully discharge each segment of each dot. The laser scanner assembly would typically be part of a laser printer.
