Description
最大符号化単位別符号化深度及び符号化モードについての情報は、一つ以上の符号化深度情報について設定され、符号化深度別符号化モードについての情報は、符号化単位別予測単位の分割タイプ情報、予測モード情報及び変換単位のサイズ情報などを含んでもよい。また、符号化深度情報として、深度別縮小情報が抽出されもする。
次の現在ピクセルPの左側境界までの距離W1、及び右側境界までの距離W2を考慮し、現在ピクセルPを下端に延ばしたとき、最下側境目に位置する仮想のピクセルA 161の値を、次の数式2のように計算する。
A=(C*W1+leftdown pixel*W2+((W1+W2)/2))/(W1+W2) (2)
数式(2)で、W1+W2の値が、2^nのように、2の指数乗である場合、A=(C*W1+leftdown pixel*W2+((W1+W2)/2))/(W1+W2)は、シフト演算を介して、除法演算なしに、次の数式:A=(C*W1+leftdown pixel*W2+2^(n−1))>>nのように計算される。
B=(C*h1+rightup pixel*h2+((h1+h2)/2))/(h1+h2) (3)
h1+h2の値が、2^mのように、2の指数乗である場合、B=(C*h1+rightup pixel*h2+((h1+h2)/2))/(h1+h2)は、次の数式:B=(C*h1+rightup pixel*h2+2^(m−1))>>mのように、除法演算なしに、シフト演算を介して計算される。
図25を参照すれば、現在ピクセルPの予測子として、左側周辺ピクセルBが利用され、dxが2^nの値を有する場合、左側周辺ピクセルBの位置である(0,i+j*dy/dx)を決定するために必要なj*dy/dx演算は、(i*dy)/(2^n)であり、かような2の指数乗で除法を行う演算は、(i*dy)>>nのように、シフト演算を介して具現されるので、演算量が減少する。
