Abstract: JPEG (Joint Photographic Experts Group) images are encoded and decoded as fast as possible for a variety of disparate applications. A novel structure stores the 8×8 Discrete Cosine Transform (DCT) blocks after entropy decoding in a JPEG decoder or after the Forward Discrete Cosine Transform (FDCT) in the JPEG encoder to use as an intermediate format between transform processes. The format was chosen to speed up the entropy decode and encode processes and is based on the information needed for the JPEG Huffman entropy coding, but lends itself to fast execution of other DCT based transforms, including arithmetic entropy coding.

Abstract: A method and apparatus for halftoning digital images renders color data subject to constraints on the number of colorants which can be deposited on a single pixel and constraints on consecutive pixels rendered with the same color. The color data to be rendered is mapped into a second data set in an achievable color gamut space. Then, using a digital halftoning method in the achievable color gamut space, the second data set is rendered, so that the constraints are satisfied.

Abstract: Methods and systems herein provide for color conversion in the real domain from an input color space to an output color space using a color conversion table that includes color values defined in the output color space corresponding to color values in the input color space, a table of scaling factors, and a conversion engine operable to group the real domain image data into blocks of pixels. The conversion engine, for each block of pixels, converts a color value in the block of pixels from the input color space to the output color space according to the color conversion table, computes differences between the color value and color values of pixels in the block, scales the computed differences according to the table of scaling factors, and adds the scaled differences to the converted color values to convert the pixel color values to the output color space.

Abstract: The scaling down of data is provided. At least two blocks of transformed data samples representing at least two blocks of original data samples are received. One of at least two tables of constants is selected wherein each table of constants is capable of reducing the number of transformed data samples by a different factor. The constants taken from the selected table are applied to the at least two blocks of transformed data samples to produce one block of transformed data samples representing one block of final data samples. The data is processed one dimension at a time by multiplying the data in one dimension with selected constants taken from previously developed tables corresponding to the desired scale down factor. Scaling down by different factors in each dimension as well as scaling down in one dimension and scaling up in the other dimension may be achieved. In addition, the de-quantization of the quantized transform coefficients may be accomplished by pre-multiplication of the selected constants when the quantization values are known. In a similar way the re-quantization may be accomplished by a pre-division of the selected constants. Both de-quantization and re-quantization may be combined when the input quantized transform coefficients and output quantized transform coefficients are desired.

Abstract: Provided are a method, system, and article of manufacture for mapping an input color value in an input color space to an output color value in an output color space. A lookup table in a computer readable medium maps an input value having color components in an input color space to an output color value in an output color space. The lookup table has n number of possible values for a fixed color component in the input color space and less than n number of possible values for t color components in the input color space. An input value in the input color space is received and a determination is made of surrounding input values in the lookup table surrounding the input value in a t dimensional space, wherein each surrounding input value has a same value for the fixed color component. A determination is made from the lookup table of surrounding output values in the output color space to which the determined surrounding input values map. The determined input and output surrounding values and the input value are used to estimate an output value in the output color space for the received input value in the input color space.
