Naprava za kodiranje slike, pri čemer naprava obsega: intrapredikcijsko enoto (150), ki je zasnovana za določanje intrapredikcijskega načina, za generiranje referenčnih točk, ki ustrezajo nerazpoložljivim referenčnim točkam, za adaptivno filtriranje referenčnih točk v skladu z intrapredikcijskim načinom in za generiranje predikcijskega bloka z uporabo referenčnih točk, določenih z intrapredikcijskim načinom; transformacijsko enoto (120), ki je zasnovana za transformiranje preostalega bloka, ki je preostali signal med prvotnim blokom in predikcijskim blokom, ki ga je generirala intrapredikcijska enota (150), za generiranje transformacijskega bloka; kvantizacijsko enoto (130), ki je zasnovana za kvantiziranje transformacijskega bloka, da generira kvantizirani blok; in entropijsko kodirno enoto (140), ki je zasnovana za entropijsko kodiranje kvantiziranega bloka, pri čemer intrapredikcijska enota (150) adaptivno filtrira referenčne točke glede na velikost predikcijskega bloka za intrapredikcijske načine, ki obstajajo med horizontalnim načinom in intrapredikcijskim načinom, ki ima smer 45° glede na horizontalni način, pri čemer se, kadar se referenčne točke filtrirajo za drugi usmerni intrapredikcijski način, referenčne točke filtrirajo tudi za prvi usmerni intrapredikcijski način, ki je bliže intrapredikcijskemu načinu, ki ima smer 45° glede na horizontalni način, kot je drugi usmerni intrapredikcijski način, pri čemer drugi in prvi usmerni intrapredikcijski način obstajata med horizontalnim načinom in intrapredikcijskim načinom, ki ima smer 45° glede na horizontalni način, pri čemer se filter uporabi v intrapredikcijskem načinu, ki ima smer 45° glede na horizontalni način in se ne uporabi v horizontalnem in vertikalnem načinu, pri čemer se število intrapredikcijskih načinov, v katerih se uporabi filter, povečuje, ko se velikost predikcijskega bloka povečuje, pri čemer intrapredikcijska enota (150) ne filtrira referenčnih točk predikcijskega bloka, ki je manjši od vnaprej določene velikosti.
  2. 2. Naprava po zahtevku 1, pri čemer, kadar je intrapredikcijski način planarni način, intrapredikcijska enota (150) generira predikcijski blok z uporabo vogalne referenčne točke, leve referenčne točke in zgornje referenčne točke.
