Method of operating an image sensor

A method of operating an image sensor comprising a pixel array of a plurality of red pixels, a plurality of green pixels, a plurality of blue pixels, and a plurality of white pixels, the method comprising:

• generating a rhombus green binning area by selecting a first green pixel, a second green pixel, a third green pixel, and a fourth green pixel from pixels of the pixel array, the first green pixel, the second green pixel, the third green pixel, and the fourth green pixel being positioned at corners of a rhombus;
• performing a rhombus pixel binning operation on the rhombus green binning area;
• and
• generating image data from the first green pixel, the second green pixel, the third green pixel, and the fourth green pixel.

A method of operating an image sensor comprising a pixel array of a plurality of red pixels, a plurality of green pixels, a plurality of blue pixels, and a plurality of white pixels that are arranged in a plurality of pixel columns and a plurality of pixel rows, the method comprising:

• selecting a first red pixel and a second red pixel from a first pixel column;
• selecting a third red pixel from a first pixel row positioned at a midpoint between the first red pixel and the second red pixel;
• generating a first isosceles triangular binning area, wherein the first red pixel, the second red pixel and the third red pixel are positioned at corners of the first isosceles triangular binning area;
• generating a red binning pixel by performing a red pixel binning operation on the first isosceles triangular binning area;
• selecting a first blue pixel and a second blue pixel from a second pixel column;
• selecting a third blue pixel from a second pixel row positioned at a midpoint between the first blue pixel and the second blue pixel;
• generating a second isosceles triangular binning area, wherein the first blue pixel, the second blue pixel, and the third blue pixel are positioned at corners of the second isosceles triangular binning area;
• generating a blue binning pixel by performing a blue pixel binning operation on the second isosceles triangular binning area;
• and
• generating image data from the red binning pixel and the blue binning pixel.
