Abstract

Avsoksomformnlngaanordnlng som anvender en oppslagB-tabell (29) for hvert polarkoordlnatpunkt son skal omdannes. Idet en fylltelling og et toppdetekterlngs-slgnal for punktet lagres. Fylltelllngsslgnalet representerer antallet av uadreeserbare blldeelementer sod skal fyllea tilhørende punktet. De uadreeserbare blldeelementene fylles med måldata a om tilsvarer avstanden derav. Fleradresserbare blldeelementer og de uadresserbare blldeelementer tilhørende disse fylles med toppdata bob utledes fra det maksimale av eksisterende måldata på koordinaten eller data lageret 1 oppfrlsknlngshokoamelsen (39) for koordinaten.
