Abstract: Rapid loading of chromatically interleaved RGB data into SSE registers as chromatically segregated RGB data for print processing is achieved through a loading algorithm that relies on a reduced number of memory references. An exemplary method comprises the steps of loading into SSE registers a first instance of data of a first and a second color from interleaved RGB data two bytes at a time, creating in SSE registers a second instance of the data of the first and second colors, removing from SSE registers one instance of the data of the second color, packing into one SSE register one instance of the data of the first color, removing from SSE registers one instance of the data of the first color and packing into one SSE register one instance of the data of the second color.

Abstract: A method and apparatus for image compositing in an apparatus a device in which available memory is at a premium are disclosed. The apparatus includes a first memory that receives a video input signal, in multiple portions. The first memory has a storage capacity less than the entire video image. Data within the first memory is encoded to form encoded video image portions. The entire image is thus encoded, video image portion by video image portion. A second image is combined with image portions in the first memory prior encoding such video image portions. The apparatus may, for example, be an electronic component or components forming a video or image processing pipeline, used in a portable device.

Abstract: An improved printer is provided which includes a separate hardware compression module and hardware decompression module contained within the ASIC of the print engine. A "Request Counter" register is decremented each time memory is requested to store a block of bitmap image data. When the Request Counter decreases to a predetermined value, the current size of the remaining "free memory" space is evaluated. If this free memory is less than another predetermined value (a "low water mark"), then blocks of data that have already been stored in the printer's memory are sent to the compression module to be compressed before the printer literally runs out of free memory, and the printer can continue storing and processing more incoming print job data. By thus preserving some of the free memory, the printer can continue to process or rasterize more print data while the compression hardware simultaneously operates independently to compress one or more blocks of data. Since the compressor hardware operate independently of the printer's microprocessor, the printer can continue to process further data during the actual compression operations, thereby preventing the printer's microprocessor from becoming idle, which otherwise would become a very inefficient utilization of the printer's processing power. The present invention is especially useful in processing color data, especially in printers containing relatively small quantities of RAM, since color data typically requires four (4) planes of bitmap image data per page to be printed.

Abstract translation: 提供了一种改进的打印机，其包括单独的硬件压缩模块和包含在打印引擎的ASIC内的硬件解压缩模块。 每次请求存储器存储位图图像数据块时，“请求计数器”寄存器递减。 当请求计数器减小到预定值时，评估剩余的“空闲内存”空间的当前大小。 如果该可用存储器小于另一个预定值（“低水位”），那么已经存储在打印机的存储器中的数据块被发送到压缩模块，以在打印机实际上用尽空闲存储器之前被压缩 并且打印机可以继续存储和处理更多输入的打印作业数据。 通过这样保留一些可用存储器，打印机可以继续处理或光栅化更多打印数据，同时压缩硬件同时独立地压缩一个或多个数据块。 由于压缩机硬件独立于打印机的微处理器进行操作，打印机可以在实际的压缩操作期间继续处理进一步的数据，从而防止打印机的微处理器变空闲，否则将使打印机的处理能力成为非常低效的利用。 本发明特别适用于处理彩色数据，特别是在包含相对较少数量的RAM的打印机中，因为彩色数据通常需要打印每页四（4）个位图图像数据的平面。

Abstract: An image processing device comprises an encoder for encoding inputted image data in the form of fixed length compression. The encoded data encoded in the form of the fixed length compression by the encoder is stored in a hard disk through an encoded data buffer which is a toggle buffer. Accordingly, the image data can be stored in the hard disk at a constant speed, and a capacity of the encoded data buffer can be minimized since the data amount after data compression is decided. As a result, it is not necessary to provide a semiconductor memory corresponding to storage of one screen, so that a low cost image processing device is obtained.

Abstract: Streaming magnetic tape system used as an electronic recirculating feeder for copiers and printers. Scanned and digitized original pages are stored on tape by high speed thin film parallel heads. The tape is reversed and the heads are shifted after one-half of the pages are stored on the tape. Storage of the second half of the pages results in the tape being back at the place of beginning, thus eliminating time-consuming rewinds. In one embodiment, the pages are counted before recording to ascertain the middle tape reversal location.

Abstract: The surface of an original is scanned in the direction of lines with a laser beam to obtain read-out data from the reflected light beam from the original, and the read-out data for a line are first stored in a line buffer memory. Then, during the scanning for the next line by the laser beam the data which have been stored in the line buffer memory are read out and used to modulate a laser beam, with the laser beam thus modulated being led to a light-sensitive drum for making duplication of information of the read-out data.
