An information processing device, configured to divide the frequency components of image data into a plurality of frequency bands, includes an analysis filtering unit configured to perform analysis filtering for dividing the frequency components into highband components and lowband components recursively, and a holding unit configured to supply, in sync with timing for holding data supplied as a computation result of the analysis filtering by the analysis filtering unit, the data already held, which is data necessary for computation of next analysis filtering to the analysis filtering unit.
