    摘要: When a periodic pattern is not included in image data 210, a prediction error encoding unit 204 outputs the variable-length code of a prediction error quantization value 214 generated by prediction encoding as compressed data 215. When the periodic pattern is included in the image data 210, a periodic pattern encoding unit 208 outputs only information about the periodic pattern as the compressed data 215, while the output of the prediction error encoding unit is stopped. On the decompression side, while the copy instruction of a pixel value before one cycle from the compressed data is not detected, the decompression operation in a normal prediction encoding system is executed. When the instruction is detected, the pixel value one cycle before, internally stored is copied and outputted.

    摘要: An image compression device having a prediction unit for predicting a value of a compressing target pixel from peripheral values, and quantizing prediction error between a prediction value of the prediction unit and a value of an actual pixel in a predetermined quantizing step, comprising: a specific pixel level difference evaluation unit sequentially calculating the difference value between the level values as a sum of the prediction values corresponding to each of the compressed pixel immediately before the compressing target pixel and peripheral compressed pixels adjacent to the pixel and the quantization value of the prediction error, and evaluating the sameness of the difference value; and a quantization switching unit controlling the quantization in the quantizing step more precise than the quantizing step used when the difference value continuously indicates the same value as a result of the evaluation by the specific pixel level difference evaluation unit.

    摘要: The present invention provides a data compression method in which a plurality of consecutive characters of a data string to be compressed are set as a character string to be searched for. Bits of a bit string representing the set character string are allocated to at least two codewords. Thus, first and second searching codewords are generated. These first and second codewords are used as array addresses. Fist and second array tables are prepared, in which information on the past occurrence positions of the set character string is previously entered as the contents thereof. When the first and second codewords are generated from the character string to be compressed, the first and second array tables are looked up by using these codewords as the addresses of the arrays. When results of looking up these tables match with each other, it is found that the set character string occurred in the past. Thus, information on the past occurrence position information of the set character string is obtained according to the obtained array content. Then, this information is encoded, so that data compression is performed. Thus, the amount of memory needed for the tables is significantly reduced, while information on the past occurrence position of the set character string is obtained without reducing a searching speed.
