摘要： An Image Signal Processing unit (ISP) has at least one fixed-size line buffer which is smaller than the width of the image buffer. To handle the image data, the image buffer is divided into regions which are sequentially loaded into the at least one fixed-size line buffer of the ISP for processing. Since functions of the ISP operate with neighboring pixels of the target pixel, margins of the regions need to be transmitted as well. After processing by the ISP, the data is encoded which includes a DCT, Quantization, and VLC. The result is then stored in segments in a buffer storage. VLC also inserts a Restart Marker which is used as a pointer to stitch together all the segments thus producing a new and seamless image.

摘要： Two-dimensional blocks of line-work image data are subjected to: fractal reordering; run length encoding of the pixel values of the fractal re-ordered data, index encoding of the run length encoded pixel values; and entropy encoding of the index encoded pixel values and run lengths. This lossless, but in case of applying a quantisation step, lossy image data compression and decompression method is particularly suitable for handling image data in a printer environment, and more particularly for handling image data comprising line work data or both raster images and line work data.

摘要： In a data compressing section, an image decompressing section decompresses compression RGB data, obtained by lossy compression, to generate decompression RGB data. A second segmentation section generates a decompression segmentation signal. Further, a differential extracting section generates a differential signal that indicates a differential between the segmentation signal and the decompression segmentation signal. A second signal compressing section generates a compression differential signal. Then, this compression differential signal is outputted as storage-use segmentation signal (signal indicating segmentation information), to a data storage section, together with the compression RGB data. The compression differential signal is smaller in size than the segmentation signal. This allows for reduction of a time required for data output and reduction of a required storage space.

摘要： A display data compression method can execute both irreversible compression and reversible compression, wherein display data are divided into a plurality of two-dimensional blocks, each of which is subjected to compression. In the irreversible compression, display data of each block are subjected to discrete cosine transform, quantization using a quantization table, one-dimensional rearrangement, and Huffman coding using one-dimensional Huffman table. In the reversible compression, display data of each block are subjected to scanning and compression, which are repeatedly performed by changing the scanning method therefor, so as to produce compressed data having the smallest number of effective bits. In expansion, the compressed data are decoded so that the decoded data are combined together over the blocks, thus restoring the original display data.

摘要： A printer driver software product includes machine readable instructions for a computer to compress bi-level page description date. The computer, in accordance with the instructions, checks to determine if an edge of a black region in a line of the page is within a predetermined range of pixels from an edge of a black region in a previous line of pixels. If the edge falls within the predetermined range then a symbol is written indicating the presence of the edge and the offset from the referenced edge in the previous line. The end of each line of pixels is determined on the basis of a parameter indicating page width.

摘要： There is disclosed in embodiments methods relating to the compression of printing hints. The method in embodiments generates a first set of image pixels having corresponding printing hints. The printing hints are then adjusted to produce a second set of image pixels processed in such a way that an end printed result is visually equivalent to a printed result using the first set of image pixels thereby reducing the entropy in the printing hints. The method improves the compression ratio of an image using printing hints by adjusting the printing hints of pixels that are zero or fully saturated. The printing hints are adjusted in such a way to reduce the complexity of the printing hints.

摘要： A method and system for image coding, wherein an image is divided into a plurality of blocks for scanning. The pixels values in the scanned block are represented by a plurality of level-run value pairs, wherein the level value is indicative of a non-zero pixel value and the run value is indicative of the number of consecutive zero pixel values preceding the non-zero pixel value. A plurality of contexts indicative of the level-run value pairs are conveyed to a decoder for allowing the decoder to reconstruct the image based on the contexts. The assignment of the contexts is also based on the level value of a preceding level-run pair. Additionally, instead of an end-of-block symbol, the number of non-zero coefficients is provided to the decoder prior to conveying the contexts thereto.
