An image decoding apparatus includes a first decoding unit configured to decode a bit stream that is generated by using a first variable length encoding system, so as to generate an intermediate stream, a second decoding unit configured to decode a bit stream that is generated by using a second variable length encoding system, so as to generate a syntax element, a syntax conversion unit configured to convert the syntax element that is generated, from syntax of the second variable length encoding system into syntax of the first variable length encoding system, and a first encoding unit configured to encode the syntax element that is syntax-converted, so as to generate the intermediate stream.
