MATCH MSB DIGITAL IMAGE COMPRESSION |
摘要 |
Methods, apparatus and computer readable medium are described that compress and/or decompress a digital image in a lossless or a lossy manner. In some embodiments, a display controller may compress a digital image by generating a symbol for each pel of the digital image. In particular, the symbol may represent a pel via a match vector and a channel error vector. The match vector may indicate which quantized channels of the pel matched quantized channels of a previous pel. Further, the channel error vector may comprise a lossless or lossy channel for each quantized channel of the pel that did not match a corresponding quantized channel of the previous pel. The channel error may also comprise a lossless or lossy channel error for each quantized channel of the pel that matched a corresponding quantized channel of the previous pel. |
