1. A single-plate color imaging element which is formed by disposing color filters on a plurality of pixels formed with photoelectric conversion elements arrayed in a horizontal direction and a vertical direction, wherein
an array of the color filters includes a basic array pattern in which the color filters are arrayed according to an array pattern corresponding to M×N (M and N are even numbers equal to or more than 6) pixels in a horizontal direction and a vertical direction, and is formed by repeatedly arranging the basic array pattern in the horizontal direction and the vertical direction, the basic array pattern includes two each of two types of a first sub array and a second sub array in which the color filters are arrayed according to an array pattern corresponding to (M/2)×(N/2) pixels, the first and second sub arrays being arranged mutually adjacent in the horizontal direction and the vertical direction, the color filters include first filters corresponding to a first color with one or more colors and second filters corresponding to a second color with two or more colors whose contribution rates for acquiring a brightness signal are lower than a contribution rate of the first color, a ratio of a number of pixels of the first color corresponding to the first filter being greater than a ratio of a number of pixels of each color of the second color corresponding to the second filters, the first filters are arranged in a rectangular shape in an outer peripheral portion of the first sub array, and are arranged in a center portion of the second sub array, and one or more of the second filters corresponding to each color of the second color are arranged on each filter line of the array of the color filter in the horizontal and vertical directions in the basic array pattern. |
