ABSTRACT:
A wavelet transformation device for performing wavelet transformation at a plurality of division levels as to image signals. A horizontal filtering unit subjects the image signals to horizontal direction lowband analysis filtering and highband analysis filtering. Buffers which are independent for each of the division levels, hold frequency components, which are generated as the results of the horizontal direction analysis filtering by the horizontal filtering unit, for each of the division levels. Interleaving devices comprising at least one interleaving unit interleaving brightness components and color difference components of the image signals and interleaving highband components and lowband components of buffered filter results.
