Abstract
In a time/space-division filtering, a moving image signal in a certain resolution-hierarchy, for which time hierarchizing is performed, is divided into a time low-band signal and a time high-band signal. A moving image signal, which has the moving image signal corresponding to the time high-band signal reconstructed by employing the time low-band signal and the time high-band signal, is generated. A reduced image signal having the moving image signal reduction-processed is generated. A high-band generating process by space hierarchizing is performed for the time high-band signal, thereby to generate a time high-band/space high-band signal. The time low-band signal, the reduced image signal, and the time high-band/space high-band signal are assumed to be a division result respectively. The time/space-division filtering is recursively performed for the time low-band signal that is assumed to be a moving image signal of which the time-resolution is lower by one stage, and the reduced image signal that is assumed to be a moving image signal of which the space-resolution is lower by one stage, thereby to hierarchize the moving image signal in a multi-step.
