COLOR IMAGING ELEMENT AND IMAGING DEVICE

摘要

A color filter array of a color imaging element is formed with a basic array pattern repeatedly disposed in a horizontal direction and a vertical direction. The basic array pattern is formed with RGB filters arrayed in an array pattern corresponding to 5×5 pixels in the horizontal direction and the vertical direction. A ratio of all pixel numbers of a G pixel is made larger than a ratio of a pixel number of each color of RB. The G filter is disposed in each line in the horizontal, vertical and oblique directions of the color filter array. One or more R and B filters are disposed in each filter line in the horizontal and vertical directions of the color filter array in the basic array pattern. Filters of different colors are adjacently disposed in each of the horizontal, vertical and oblique directions of the R and B filter.

主权项

1. A single-plate color imaging element including:
multiple pixels including photoelectric conversion elements 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 in which the color filters are arrayed in an array pattern corresponding to N×N (N is an odd number equal to or greater than 5) pixels in the first direction and the second direction, and the array is formed by repeatedly disposing the basic array pattern in the first direction and the second direction; the color filters include 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 the first color, and a ratio of all pixel numbers of the first color corresponding to the first filter is larger than a ratio of a pixel number of each color of the second colors corresponding to the second filters; one or more first filters are disposed in a filter 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 filter; each of the second filters of each color of the second colors is disposed in each filter line in the first direction and the second direction in the basic array pattern one by one; and in the second filter of at least one color in the array of the color filter, the second filter or the first filter of a different color from that second filter is adjacently disposed in each direction including the first direction to the fourth direction.
