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.

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 and apparatus for printing data on a print medium is disclosed. The apparatus is configured to format print data to pixel data, the pixel data including pixel values; identify a grid of pixels having a predetermined pattern of pixel values; obtain predetermined pcode grid from memory for the identified grid of pixels; and send the predetermined pcode grid to controller circuit for printing.
摘要:
An apparatus and method are described for adjusting the color balance of a display. According to the method, a sensor of the apparatus detects the color temperature of ambient light. A controller of the apparatus adjusts the color balance of the emissive display based on the detected color temperature of ambient light.

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.

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.

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.

摘要:
The invention provides an architecture and method for implementing a programmable I/O interface. The primary function provides a generic reconfigurable interface for serial communications between a laser printer controller and the print mechanism. The design also supports vertical page synchronization (top of page detection).
