Abstract
An entropy encoder includes: a memory for storing a code table in a compressed data format in which continuing digits "1" that continue successively from the most significant bit of a code word for a predetermined number of bits are removed, together with a control code indicative of the type of the original code word, and a code word restoring unit for restoring the original code word from the compressed code word by supplementing a predetermined number of digits "1" to the compressed code word according to the type of the original code word.
