Abstract
According to a data conversion method and apparatus, an original signal is wavelet-transformed with a desired expansion count to generate transformed data. The transformed data is corrected such that a difference between the original signal and a value obtained by inversely wavelet-transforming the transformed data falls within a desired tolerance range, thereby generating the corrected transformed data as compressed data in which the original signal is compressed.
