    • A display data compression method can execute both irreversible compression and reversible compression, wherein display data are divided into a plurality of two-dimensional blocks, each of which is subjected to compression. In the irreversible compression, display data of each block are subjected to discrete cosine transform, quantization using a quantization table, one-dimensional rearrangement, and Huffman coding using one-dimensional Huffman table. In the reversible compression, display data of each block are subjected to scanning and compression, which are repeatedly performed by changing the scanning method therefor, so as to produce compressed data having the smallest number of effective bits. In expansion, the compressed data are decoded so that the decoded data are combined together over the blocks, thus restoring the original display data.
    • 显示数据压缩方法可以执行不可逆压缩和可逆压缩,其中显示数据被分成多个二维块,每个二维块经受压缩。 在不可逆压缩中,使用一维霍夫曼表,对每个块的显示数据进行离散余弦变换,使用量化表进行量化,一维重排和霍夫曼编码。 在可逆压缩中,对每个块的显示数据进行扫描和压缩,通过改变其扫描方法来重复执行扫描和压缩,以便产生具有最小有效位数的压缩数据。 在扩展中,压缩数据被解码,使得经解码的数据通过块组合在一起,从而恢复原始显示数据。
