In　order　to　solve　the　problem　which　pixels　located　at　the　boundary　of　moving　objects　can　not　be　predicted　accurately　in　H.264　intra　prediction,　an　adjacent　pixels-based　intra　prediction　algorithm　is　presented　in　this　paper.　Because　the　correlation　of　pixels　in　the　same　block　is　more　closed,　some　pixels　are　taken　as　references　to　predict　other　pixels　in　the　same　block.　Furthermore,　new　order　of　prediction　modes　is　deduced　according　to　the　novel　intra　prediction　algorithm.　The　test　results　indicate　that,　the　adjacent　pixels-based　intra　prediction　algorithm　can　solve　the　problem,　which　is　mentioned　above　and　improve　coding　efficiency　remarkably.
