Abstract:
A signal editing device comprising:dividing means for dividing a digital signal into processing blocks in the frequency and space domains; and processing means for processing said digital signal independently in units of said processing blocks, said processing being performed in both the frequency and space domains, wherein at least one processing block having a predetermined frequency component of said digital signal is processed; wherein, said processing means performs synthesizing processing on at least two moving pictures; an image frame from each of said moving pictures is extracted at each editing point by performing dividing processing in the time domain; and a desired region to be processed is extracted out of the extracted image frames of the moving pictures by performing dividing processing in the space domain while low frequency components of said moving pictures are extracted by performing dividing processing in the frequency domain, whereby a reduced image is generated from said low frequency components, and a synthesized video image is obtained by combining a result of said dividing processing in said frequency and space domains.
