Imaging device, electric charge readout method, and imaging apparatus

An imaging device comprising:

• red pixels;
• blue pixels;
• first green pixels;
• and
• second green pixels adjacent to the respective first green pixels in a first direction, which is the direction in which electric charge accumulated in the pixels is read,
• wherein the dimension of the first and second green pixels in a second direction perpendicular to the first direction is twice the dimension of the first and second green pixels in the first direction, wherein the dimension of the red pixels in the second direction is twice the dimension of the red pixels in the first direction, wherein the dimension of the blue pixels in the second direction is twice the dimension of the blue pixels in the first direction,
• wherein the pixels are arranged in groups of four pixels, with each group of four pixels including one of the first green pixels and one of the second green pixels in a first row, and one of the red pixels and one of the blue pixels in a second row immediately below the first row, and
• wherein for each group of four pixels a floating diffusion section is located in an area centered between the four pixels,
• wherein each of the first green pixels and the corresponding one of the second green pixels are disposed adjacent to each other in the first direction,
• a first red pixel of the red pixels and a first blue pixel of the blue pixels are disposed on one side of the adjacent first and second green pixels in the second direction perpendicular to the first direction, the adjacent first/second green pixels and the first red/blue pixels sandwiching a first electric charge extracting section for extracting electric charge from a first in-pixel electric charge accumulation means, and
• a second red pixel of the red pixels and a second blue pixel of the blue pixels are disposed on the other side of the adjacent first and second green pixels in the second direction perpendicular to the first direction, the adjacent first/second green pixels and the second red/blue pixels sandwiching a second electric charge extracting section for extracting electric charge from a second in-pixel electric charge accumulation means.
