摘要： A pixel block (300) is compressed by providing a respective color component prediction for each pixel (310-318) in the block (300). A difference between color components of two neighboring pixels (312, 316) is calculated and compared to a threshold. If the difference is smaller than the threshold, the prediction is calculated based on a first linear combination of the color components of these two neighboring pixels (312, 316). However, if the difference exceeds the threshold, a second or third linear combination of the color components of the neighboring pixels (312, 316) is employed a prediction. A guiding bit (470) associated with the selected linear combination. A prediction error is calculated based on the color component of the pixel (318) and the provided prediction. The compressed block (400) comprises an encoded representation (480) of the prediction error and any guiding bit (470).

摘要： In an image-encoding scheme, an input image is decomposed into several image blocks (600) comprising multiple image elements (610), e.g. pixels or texels. The image blocks (600) are then encoded into encoded block representations (700). Such a block representation (700) comprises a color codeword (710), an intensity codeword (720) and a sequence (730) of intensity representations. The color codeword (710) is a representation of the colors of the image elements (610) of the block (600). The intensity codeword (720) is a representation of a set of multiple intensity modifiers for modifying the intensity of the image elements (610) in the block (600). The representation sequence (730) includes an intensity representation for each image element (610) in the block (600), where a representation identifies one of intensity modifiers in the intensity modifier set. During decoding, the color and intensity codewords (710, 720) and intensity representations (730) are used to generate a decoded representation of the image elements (610) in the block (600).

摘要： A pixel block (300) is losslessly compressed into a candidate compressed block. If the bit length of the candidate block exceeds a threshold value, the property values of the pixels (310-317) in the block (300) are quantized and the quantized values are losslessly compressed into a new candidate compressed block. The procedure is repeated until a candidate compressed block having good image quality and a bit length below the threshold value is found. A compressed representation (400) of the block (300) is determined based on the found candidate compressed block (420) and an identifier (410) of the used quantization parameter.

摘要： A pixel block (300) is compressed by determining a reference set of multiple reference property values (10-14). A value index associated with a reference property value of the reference set is assigned to each pixel (310-316) in the pixel block (300) based on the original property value of the pixel (310-316). A prediction of the value index is provided based on the value index assigned to at least one neighboring pixel (314, 316) in the pixel block (300). A prediction error is calculated based on the value index assigned to a pixel (316) and its value index prediction. The compressed pixel block (400) comprises encoded representations (424) of the prediction errors and an encoded representation (410) of the reference set.

摘要： A sample-sharing pattern covering a set of pixels for use in an anti-aliasing system where each pixel has a pattern of sample points. A first sampling point is provided at a corner of the pixel, and second and third sampling points are provided at separate borders of the pixel, which do not intersect the corner sample. Moreover, the sample point pattern of each pixel is a mirror image of and different from the pattern of a neighboring pixel.
