Figures (al, (bl, (C1) are color layout diagrams of the filter described in the above reference documents. R, G, and B indicate the three primary colors of red, green, and blue, respectively. Fig. 2 (a) is a vertical stripe, Fig. 2 (b) is a diagonal stripe, Fig. 2 (C)
are arranged in a zigzag pattern.
フィルター配置を考える時に重要な点は、少ない画素数
で如何に自然な混色を得る事が出来るかである。しかし
ながら従来例ではフィルター配置が目立ち自然な混色に
は問題があった。本発明の目的は、簡単な構成で自然な
混色の可能なカラーフィルターを提供するものである。When considering filter placement, an important point is how natural color mixture can be obtained with a small number of pixels. However, in the conventional example, the filter arrangement was conspicuous and there was a problem in natural color mixing. An object of the present invention is to provide a color filter that has a simple configuration and allows natural color mixing.

) The disadvantage of the vertical stripe type is that the vertical stripes stand out. Figure 2 (b), (C1 is slightly improved compared to Figure 2 (a), but diagonal stripes and zigzag bumps are still noticeable.The problem with these is that all three primary colors are lined up in the same direction. This is due to the fact that all the colors are arranged in the directions indicated by the arrows 21, 22, and 26 shown in FIG.

The rows arranged in the order of . . . and the rows arranged in the order of BGRBGR coexist. That is, assuming that the first, second, and third primary colors are R, G, and B, respectively, the rows arranged in the order of the first, second, and third primary colors, and the third, second, and first primary colors are It is characterized by periodically alternating rows arranged in the order of the primary colors. In this way, the three primary colors are arranged in different ways, reducing the impression that they are arranged in the same direction. By using the present invention, the unnaturalness of the filter arrangement, which was a problem in the conventional example, can be greatly improved.

This is an example of the present invention in which a GB array and a BGR array are used alternately. Arrow 11 indicates the direction in which G is arranged, arrow 12 indicates the direction in which B is arranged, and arrow 13 indicates the direction in which R is arranged. In contrast to the conventional example in which all colors are arranged in the same direction, in this embodiment, G is arranged downward to the right and RlB is arranged downward to the left. The relative brightness of G is 59%, while the sum of the relative brightness of R and B is 41%.
As a result, the slams of the scene are arranged in different directions. Therefore, neither button is visually noticeable, and color mixing is good. FIG. 1 (bl is another embodiment of the present invention. G is a zigzag arrangement every three rows, and RGB arrangement and BGR arrangement are used alternately for each row. Conventional zigzag arrangement FIG. 2 ( Compared with C1, the arrangement direction arrow 14 of G is the same, but the arrangement direction arrows 15', 1 of B and R are the same.
6 is thick (different, improving color mixing and naturalness).

The array and BGR array are used alternately. In the conventional example shown in FIG. 2 (al), B and R are also vertical stripes, whereas in this embodiment, B and R are zigzag as shown by arrows 18 and 19, improving color mixing.
