Abstract
An information processing apparatus for encoding image data, includes a filter unit for performing a filtering operation on the image data in a layer fashion to generate a plurality of subbands including coefficient data segmented on a per frequency band basis, an intermediate data storage unit for storing intermediate data generated in the middle of the filtering operation of the filter unit, a coefficient storage unit for storing the coefficient data generated in the filtering operation of the filter unit, and a coefficient rearranging unit for performing a rearranging operation to rearrange the coefficient data stored on the coefficient storage unit so that the coefficient data is output in a predetermined order. The intermediate data storage unit writes and reads data thereon at a speed higher than the coefficient storage unit and being smaller in storage capacity than the coefficient storage unit.
