Abstract: front page image
(EN)A color filter arrangement contains a basic arrangement pattern (P1, pattern delimited by bold border) comprising a square arrangement pattern corresponding to 5x5 pixels. This basic arrangement pattern (P1) is repeated in the horizontal and vertical directions. In the basic arrangement pattern (P1), the G filter, which is the luminance-based pixel, is at least positioned so as to form two diagonal lines. As a result, the G filter is positioned within each line in the horizontal, vertical, and diagonal directions in the color filter arrangement, while the R and B filters are positioned within each line in the horizontal and vertical directions in the color filter arrangement. In addition, the proportion of number of G pixels, which contribute the most for acquisition of a luminance signal of the basic arrangement pattern (P1), is greater than the respective proportions of the number of pixels for the other colors, namely the R pixels and B pixels; hence, the proportion is effective for simultaneous processing.
(FR)Selon l'invention, une disposition de filtre couleur comprend un motif de disposition de base (P1) (motif représenté en gras), lequel motif est constitué d'un motif de disposition quadrangulaire correspondant à 5X5 pixels, et ce motif de disposition de base (P1) se répète en direction horizontale et en direction verticale. Dans le motif de disposition de base (P1), le filtre G qui est le pixel de luminance, est placé de façon à former au moins deux diagonales. En conséquence, le filtre G est situé sur chaque ligne horizontale, verticale et diagonale dans la disposition de filtre, alors que les filtres R et B sont placés sur les lignes verticale et horizontale. En outre, la proportion du nombre de pixels G, lesquels contribuent le plus à l'acquisition d'un signal de luminance du motif de disposition de base (P1), est supérieure à la proportion du nombre de pixels d'autres couleurs, autrement dit de pixels R et de pixels B, ce qui est efficace pour un traitement simultané.
(JA)カラーフィルタ配列は、5×5画素に対応する正方配列パターンからなる基本配列パターンP1(太枠で示したパターン)を含み、この基本配列パターンP1が水平方向及び垂直方向に繰り返し配置されている。基本配列パターンP1は、輝度系画素であるGフィルタが少なくとも両対角線上に配置されている。その結果、Gフィルタがカラーフィルタ配列の水平、垂直、及び斜め方向の各ライン内に配置され、Rフィルタ、Bフィルタがカラーフィルタ配列の水平及び垂直方向の各ライン内に配置される。また、基本配列パターンP1の輝度信号を得るために最も寄与するG画素の画素数の比率は、他の色のR画素、B画素の画素数の比率よりも大きいため、同時化処理に有効である。
