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.
