    摘要： In a data compression method based on an LZW coding procedure, a list (100,101) which defines a sequence of tracing partial strings registered in a dictionary (220) is defined so that successive partial strings are arranged in groups based on given significant bits. The search of the dictionary (220) is thus made easier because the search can be restricted to a single group.

    摘要翻译： 在基于LZW编码过程的数据压缩方法中，定义了在字典（220）中登记的跟踪部分串的序列的列表（100,101），使得基于给定的有效比特来分组排列连续的部分字符串。 因此，搜索词典（220）变得更容易，因为搜索可以被限制到单个组。

    摘要： The present invention relates to an image data reconstructing apparatus for reconstructing an original image by dividing image data into a plurality of blocks each comprising NXN picture elements, performing two-dimensional orthogonal transform on each of said blocks, quantizing and encoding the result of said transform, decoding the encoded result, dequantizing and two-dimensional inverse orthogonal transforming the above result, wherein an operation associated with the multiplication is skipped if a multiplication by zero is detected when two-dimensional inverse orthogonal transform is performed. Before performing dequantization, two block volume of buffer is provided before or after performing two-dimensional inverse orthogonal transform for executing a pipeline process. Furthermore, two-dimensional inverse orthogonal transform is performed by repeating two times a process of one-dimensional inverse orthogonal transform and matrix transposition, thus the matrix transposition being performed as the result of one-dimensional inverse orthogonal transform which is stored in buffer.
