COLOR IMAGING ELEMENT AND IMAGING DEVICE

摘要

In the color imaging element and the imaging device according to an aspect of the present invention, a basic array pattern is repeatedly placed in a first direction and in a second direction, the basic array pattern includes four or more rectangular patterns each corresponding to 3×2 pixels each composed of a first filter, a color filter array includes therein grating filter lines surrounding the four directions of the rectangular pattern, the color filter array includes therein the first filters each disposed in each line in the first direction, in the second direction, in a third direction, and in a fourth direction, and the basic array pattern includes therein one or more second filters of each color, each disposed in each line in the first direction in the second direction.

1. A color imaging element as a single-plate color imaging element comprising:
a plurality of pixels composed of photoelectric conversion elements disposed in a first direction and in a second direction perpendicular to the first direction; and color filters disposed on the plurality of pixels, wherein an array of the color filters includes a basic array pattern having the color filters arranged in an array pattern corresponding to M×N (M is 8 or more and N is 6 or more) 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 a first filter corresponding to a first color having one or more colors and a second filter corresponding to a second color having two or more colors, in which a contribution ratio of the second color for acquiring a brightness signal is lower than the contribution ratio of the first color, the basic array pattern includes four or more rectangular patterns each corresponding to 3×2 pixels each composed of the first filter, the array of the color filters includes therein a grating filter line in the first direction and a grating filter line in the second direction, in which the first filter and the second filter corresponding to each color of the second colors are placed side by side surrounding the four directions of the rectangular pattern, in the array of the color filters, the 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 each corresponding to each color of the second colors are disposed in each filter line in the first direction and in the second direction.
