Title (EN) 2D SIGNAL ENCODING DEVICE
(FR) DISPOSITIF DE CODAGE DE SIGNAL 2D
(JA) 2次元信号符号化装置
Abstract: front page image
(EN)A Bayer array image encoding device comprises the following: a two-dimensional high-pass filter means for finding a GH coefficient, which is a high-pass component corresponding to the spatial coordinates of a G1 pixel, from the value of the G1 pixel and the values of the four G0 pixels adjacent to the G1 pixel; a two-dimensional low-pass filter means for finding a GL coefficient, which is a low-pass component corresponding to the spatial coordinates of a G0 pixel, from the value of the G0 pixel and the values of the four GH coefficients adjacent to the G0 pixel; a first encoding means for encoding a two-dimensional signal constituted by the GH coefficient; and a second encoding means for encoding a two-dimensional signal constituted by the GL coefficient.
(FR)La présente invention se rapporte à un dispositif de codage d'image de matrice de Bayer qui comprend les éléments suivants : un moyen de filtre passe-haut bidimensionnel destiné à trouver un coefficient GH qui est un composant passe-haut qui correspond aux coordonnées spatiales d'un pixel G1, à partir de la valeur du pixel G1 et des valeurs des quatre pixels G0 adjacents au pixel G1 ; un moyen de filtre passe-bas bidimensionnel destiné à trouver un coefficient GL qui est un composant passe-bas qui correspond aux coordonnées spatiales d'un pixel G0, à partir de la valeur du pixel G0 et des valeurs des quatre coefficients GH adjacents au pixel G0 ; un premier moyen de codage destiné à coder un signal bidimensionnel composé du coefficient GH ; et un second moyen de codage destiné à coder un signal bidimensionnel composé du coefficient GL.
(JA)ベイヤー配列画像を符号化する装置は、G1画素の値とG1画素の近傍の4つのG0画素の値とから、G1画素の空間座標に対応するハイパス成分であるGH係数を求める2次元ハイパスフィルタ手段と、G0画素の値とG0画素の近傍の4つのGH係数の値とからG0画素の空間座標に対応するローパス成分であるGL係数を求める2次元ローパスフィルタ手段と、GH係数で構成される2次元信号を符号化するための第1の符号化手段と、GL係数で構成される2次元信号を符号化するための第2の符号化手段とを備える。
