摘要： Compression of a pixel block having multiple pixels comprises calculating a respective prediction error for each pixel component of the pixels except a defined starting pixel. Respective minimum number of symbols required for representing the prediction errors are determined and used to select a symbol configuration among multiple different symbol configurations. Each such symbol configuration defines respective numbers of symbols maximally available for the different prediction errors. A compressed representation of the pixel block comprises a configuration identifier of the selected symbol configuration, a representation of the pixel value of the defined starting pixel and representations of the prediction errors calculated for the remaining pixels.

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 selecting a start depth value and a restart depth value based on the multiple depth values of the pixels (310-318) in the block START (300). A respective plane representation (430) indicative of which plane of a start or restart depth value plane is determined for the pixels (311-318). These representations (430) are employed for selecting a pixel set comprising at least one other pixel (312, 314-317) in the block (300) for a pixel (318) to be encoded. The depth value(s) of the pixel(s) (312, 314-317) in the set are used for determining a prediction of the depth value of the pixel (318). The depth value and the prediction are employed for calculating a prediction error, which is encoded. The compressed pixel block (400) comprises the encoded prediction errors (460), a start value representation (420), a restart value representation (430) and the plane representations (440).

摘要： In a high quality image-encoding scheme an input image is decomposed into several image blocks comprising multiple image elements. The image blocks are encoded into encoded block representations. Such a block representation comprises two color codewords, a color modifying codeword and optionally a sequence of color indices and color modifier indices. The color codewords define multiple discrete color representations along a line in color space. The color modifying codeword represents a set of multiple color modifiers for modifying the multiple color representations along at least one extension vector to obtain, for each color representation, a set of multiple color points. These color points of the multiple sets are located on a surface defined by the multiple color representations and the at least one extension vector. The colors of the image elements in the block are then approximated by these color points on the surface.

摘要： A tile of pixels is encoded by variable length encoding at least a first block of pixels into a first sequence of symbols and a second block of pixels into a second sequence of symbols. The symbols of the first and second sequences are co-organized into a combined sequence of symbols in which the symbols of the first sequence are readable in a first reading direction and at least a portion of the symbols in the second sequence are readable in a second, opposite reading direction. The encoding of the tile to form one or more combined sequences significantly reduces the bandwidth requirements when writing the tile to a pixel value buffer. The co-organization of the first and second sequences enables parallel reading and decoding of the first and second sequences from the pixel value buffer, thereby reducing any decoding latency.

摘要： A compressed pixel block (400) is decompressed by defining multiple available property values. At least one reference point relative the pixel block (300) is identified based on a reference codeword (410) of the compressed pixel block (400). Pixel indices of the pixels (310) are determined based on the respective positions of pixels (310) in the pixel block (300) relative the at least one reference point. These pixel indices are used for selecting among the multiple defined property values. The selected property values are then assigned to pixels (310) to be decompressed based on their determined pixel indices.
