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 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： A pixel is textured by storing a first texel reference value, a second texel reference value, and texel mapping values where each texel mapping value represents a k-tuple of (ternary) references to the first texel reference value, the second texel reference value and a third texel reference value to thereby represent a block of texels. A pixel value for the pixel is generated from the stored texel values and the pixel is displayed responsive to the generated pixel value. In some embodiments, respective pluralities of texel reference values and texel mapping values that map thereto are stored for respective ones of a plurality of overlapping blocks of texels. In further embodiments, a first mipmap value for a pixel is bilinearly interpolated from the retrieved texel values for the set of nearest neighbor texels. A second mipmap value for the pixel is generated by averaging the retrieved texel values for the set of nearest neighbor texels. A pixel value for the pixel is generated by interpolating between the first and second mipmap values. The present invention may be embodied as methods, apparatus and computer program products.

摘要： First and second codewords are determined, based on first feature vector components of the image elements in an image block, as representations of a first and second component value. Third and fourth codewords are determined, based on second vector components, as representations of a third and fourth component value. First N1 and second N2 resolution numbers are selected based on the relation of a distribution of the first vector components and a distribution of the second vector components. N1 additional component values are generated based on the first and second component values and N2 additional component values are generated based on the third and fourth component values. Component indices indicative of the generated component values are then provided for the different image elements.

摘要： The invention is applied to image processing schemes by providing at least one auxiliary block processing mode in addition to the standard default block processing mode of the scheme. An image to be decoded is divided into a number of image blocks (800) having multiple image elements (810). These blocks (800) are individually compressed by means of a default compressing mode or an auxiliary compressing mode, depending on which mode that results in a smallest error metric. A portion (980) of the resulting compressed block (900) is used to discriminate between the two modes. In the auxiliary mode, the remaining payload portion (990) of the compressed block (900) can be used for encoding purposes, whereas the default mode can in addition utilize the discriminating portion (980).
摘要翻译：除了方案的标准默认块处理模式之外，还通过提供至少一个辅助块处理模式将本发明应用于图像处理方案。要解码的图像被划分为具有多个图像元素（810）的多个图像块（800）。这些块（800）通过默认压缩模式或辅助压缩模式被单独压缩，取决于导致最小误差度量的哪个模式。所得到的压缩块（900）的部分（980）用于区分两种模式。在辅助模式中，压缩块（900）的剩余有效载荷部分（990）可以用于编码目的，而默认模式可以另外使用识别部分（980）。
