    • The present invention provides an information processing method converting a format of a structured document, comprising: a first step copying, a first storage unit, information of a pre-converted first structured document sequentially by a predetermined amount beginning from the head; a second step adding start tags and/or end tags, and an identifier tag for identifying the aforementioned start and/or end tags so that the information copied to the first storage unit becomes one complete second structured document; a third step converting the second structured document built up in the first storage unit to a target format and outputting it to a second storage as a third structured document; and a fourth step removing the start tags and/or end tags and the identifier tag added to in the second step from the third structured document retained by the second storage unit and merging with a fourth structured document.
    • 本发明提供了一种转换结构化文档的格式的信息处理方法,包括:第一步骤复制,第一存储单元,预先转换的第一结构化文档的信息顺序地从头部开始的预定量; 添加开始标签和/或结束标签的第二步骤,以及用于识别上述开始和/或结束标签的标识符标签,使得复制到第一存储单元的信息成为一个完整的第二结构化文档; 第三步骤,将在第一存储单元中构建的第二结构化文档转换为目标格式,并将其作为第三结构化文档输出到第二存储器; 以及第四步骤,从第二存储单元保留的第三结构化文档中删除在第二步骤中添加的开始标签和/或结束标签以及标识符标签,并与第四结构化文档合并。

    • 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.
    • 一种图像压缩装置,具有预测单元,用于从外围值预测压缩对象像素的值,并且在预定量化步骤中量化预测单元的预测值与实际像素的值之间的预测误差,包括: 像素电平差分评估单元,其顺序地计算电平值之间的差值,作为与压缩目标像素之前的压缩像素和与像素相邻的外围压缩像素之间的每个压缩像素的预测值的和与预测误差的量化值 ,并评估差值的相同性; 以及量化切换单元,其在与所述特定像素级差分评估单元的评估结果不同的值连续指示相同的值时,比量化步骤更精确地控制量化步长。
