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.
