Abstract

Oppfinnelsen omhandler en metode, innretning, og datamaskinprogram på en bærer for å kode et digitalt bilde. Inntil det kodede bilde passer inn i en ønsket mengde av data, repeterer metoden: å kode (402) bildet til et kodet bilde, hvor kodingen omfatter kvantisering (404) som forårsaker kompresjon med tap; å dekode (410) det kodede bildet til et bilde, hvor dekodingen omfatter invers kvantisering (412); og å øke (414) tapene i kompresjonen forårsaket av kvantiseringen.
