A color imaging device that is a single-panel type color imaging device comprising: a plurality of pixels that are constituted by photoelectric conversion devices that are arranged in a horizontal direction and a vertical direction; and a color filter of a certain color filter array arranged on the plurality of pixels, wherein the color filter array includes a basic array pattern (P, P', P", P1, P2, P3, P4) of NxN, in which a first filter that corresponds to a first color that contributes most to obtaining a brightness signal and second filters that correspond to two or more second colors (B, R) other than the first color are arranged, and the basic array pattern (P, P', P", P1, P2, P3, P4) is arranged in the horizontal direction and the vertical direction repeatedly, the first filter is arranged on two diagonal lines in die basic array pattern (P, P', P", P1, P2, P3, P4), and one or more first filters are arranged in each line of the horizontal direction and the vertical direction, a ratio of a number of pixels of the first color that corresponds to the first filter to a total number of pixels in the basic array pattern is greater than a ratio of a number of pixels of each of the second colors that correspond to the second filters to the total number of the pixels, and the color filter array includes a square array that corresponds to 2x2 pixels that are constituted by the first filter, characterized in that N is an odd number of 3 or more, and one or more first filters are arranged in each line of an upper right diagonal direction and a lower right diagonal direction of the color filter array, wherein the upper right diagonal direction is a direction of a diagonal line that rises to the right, of the two diagonal lines, and the lower right diagonal direction is a direction of a diagonal line that rises to the left, of the two diagonal lines. a plurality of pixels that are constituted by photoelectric conversion devices that are arranged in a horizontal direction and a vertical direction; and a color filter of a certain color filter array arranged on the plurality of pixels, wherein the color filter array includes a basic array pattern (P, P', P", P1, P2, P3, P4) of NxN, in which a first filter that corresponds to a first color that contributes most to obtaining a brightness signal and second filters that correspond to two or more second colors (B, R) other than the first color are arranged, and the basic array pattern (P, P', P", P1, P2, P3, P4) is arranged in the horizontal direction and the vertical direction repeatedly, the first filter is arranged on two diagonal lines in die basic array pattern (P, P', P", P1, P2, P3, P4), and one or more first filters are arranged in each line of the horizontal direction and the vertical direction, a ratio of a number of pixels of the first color that corresponds to the first filter to a total number of pixels in the basic array pattern is greater than a ratio of a number of pixels of each of the second colors that correspond to the second filters to the total number of the pixels, and the color filter array includes a square array that corresponds to 2x2 pixels that are constituted by the first filter, characterized in that N is an odd number of 3 or more, and one or more first filters are arranged in each line of an upper right diagonal direction and a lower right diagonal direction of the color filter array, wherein the upper right diagonal direction is a direction of a diagonal line that rises to the right, of the two diagonal lines, and the lower right diagonal direction is a direction of a diagonal line that rises to the left, of the two diagonal lines.
