In the color imaging element, a basic array pattern is repeatedly placed in a first direction and in a second direction, the basic array pattern includes two sets of patterns each including a first pattern corresponding to 2×2 pixels composed of first filters, a second pattern corresponding to 1×2 pixels composed of the first filters, third patterns each corresponding to 2×2 pixels each composed of second filters, and fourth patterns each corresponding to 1×2 pixels each composed of the second filters, in a color filter array, first patterns and the third patterns are alternately disposed in the first direction, and the first patterns and the fourth patterns are alternately disposed in the second direction. |

1. A color imaging element as a single-plate color imaging element having color filters disposed on a plurality of pixels including photoelectric conversion elements disposed in a first direction and in a second direction perpendicular to the first direction,
wherein: an array of the color filters includes a basic array pattern in which the color filters are arranged in an array pattern corresponding to 4×6 pixels in the first direction and in the second direction, and the basic array pattern is repeatedly placed in the first direction and in the second direction, the basic array pattern includes first filters corresponding to a first color of one or more colors and second filters corresponding to second colors of two or more colors, in which a contribution ratio of the second colors for acquiring a brightness signal is lower than a contribution ratio of the first color, the basic array pattern has two sets of patterns each including a first pattern corresponding to 2×2 pixels composed of the first filters, a second pattern corresponding to 2×1 pixels composed of the first filters, a third pattern corresponding to 2×2 pixels composed of the second filters, and a fourth pattern corresponding to 2×1 pixels composed of the second filters, in the array of the color filters, the first pattern and the third pattern are alternately disposed in the first direction, and the first pattern and the fourth pattern are alternately disposed in the second direction, in the array of the color filters, a first filter is disposed in each filter line in the first direction and in the second direction of the array of the color filters and in each filter line in a third direction and in a fourth direction inclined with respect to the first direction and the second direction, and in the basic array pattern, one or more of the second filters corresponding to each color of the second colors are disposed in each filter line in the first direction and in the second direction. |
