Color imaging element and imaging device

摘要

A color filter array of a color imaging element includes a basic array pattern P of 4×4 pixels in which RGB filters corresponding to red (R), green (G) and blue (B) are arrayed, this basic array pattern P is repeatedly disposed in a horizontal direction and a vertical direction, a G filter is disposed in each pixel line in four directions of horizontality, verticality, oblique upper right and oblique lower right, and R and B filters are disposed in each pixel line in the horizontal direction and vertical direction of the color filter array. Moreover, the color filter array includes consecutive first filters of two or more pixels in four directions of horizontality, verticality, oblique upper right and oblique lower right.

主权项

1. A single-plate color imaging element including:
multiple pixels, each of which includes a photoelectric conversion element arrayed in a first direction and a second direction which is perpendicular to the first direction; and color filters which are respectively arrayed on the multiple pixels, wherein: an array of the color filters includes a basic array pattern formed by arraying the color filters in an array pattern corresponding to 4×4 pixels in the first direction and the second direction, and the basic array pattern is repeatedly disposed in the first direction and the second direction; the array of the color filters includes a first filter corresponding to a first color of one or more colors and second filters corresponding to second colors of two or more colors whose contribution ratio to acquire a brightness signal is lower than that of the first color; one or more first filters are disposed in a pixel line in each direction including the first direction, the second direction, and a third direction and a fourth direction that incline to the first direction and the second direction in the array of the color filters, and two first filters are disposed in each pixel line in the first direction and the second direction in the basic array pattern; one second filter corresponding to each color of the second colors is disposed in each pixel line in the first direction and the second direction in the basic array pattern, respectively; and the array of the color filters includes consecutive first filters of two or more pixels in the first direction, the second direction, the third direction and the fourth direction, respectively.
