PROCESSING OF REDUNDANT FIELDS IN A MOVING PICTURE TO ACHIVE SYNCHRONIZED SYSTEM OPERATION

摘要

A METHOD FOR PROCESSING A MOVING PICTURE IN WHICH INPUT DIGITAL MOVING PICTURE SIGNALS OF A PRE-SET PICTURE RATE ARE PROCESSED IN ACCORDANCE WITH PRE-SET PICTURE PROCESSING AND THE PROCESSED DIGITAL PICTURE SIGNAL ARE TRANSMITTED. THE INPUT DIGITAL MOVING PICTURE SIGNAL HAS PLURAL FIELD PICTURES. THE PROCESSING METHOD INCLUDES A FIRST STEP OF DETECTING A REDUNDANT FIELD FROM THE INPUT DIGITAL MOVING PICTURE SIGNALS, A SECOND STEP OF ELIMINATING THE DETECTED REDUNDANT FIELD FROM THE PLURAL FIELD PICTURES, A THIRD STEP OF DECIDING, FROM A STRING OF FIELD PICTURES FROM WHICH THE REDUNDANT FIELDS HAVE BEEN ELIMINATED, THE COMBINATION OF A TOP FIELD AND A BOTTOM FIELD CONSTITUTING A FRAME TO BE PROCESSED IN ACCORDANCE WITH THE PRE-SET PICTURE PROCESSING, AND OUTPUTTING THE RESULTS OF DECISION, A FOURTH STEP OF INSERTING A PRE-SET SIGNAL IN THE FIELD PICTURE STRING FROM WHICH THE REDUNDANT FIELD HAS BEEN ELIMINATED FOR GENERATING PICTURE SIGNALS FOR PROCESSING HAVING THE SAME PICTURE RATE AS THE RATE OF THE INPUT DIGITAL PICTURE SIGNAL, AND A FIFTH STEP OF PROCESSING THE PICTURE SIGNALS FOR PROCESSING IN ACCORDANCE WITH THE PRE-SET PICTURE PROCESSING BASED UPON THE RESULTS OF DECISION.(FIG. 4)
