The two-dimensional discrete-cosine transformer includes first and second buffers for buffering input video signal data, first and second discrete-cosine transformers for two-dimensionally discrete-cosine-transforming the signals buffered by the first and second buffers, and first and second output buffers for buffering the signals transformed by the first and second discrete-cosine-transformers to output it to a data output line, thereby efficiently using a built-in data memory.
