Patent ID: 11588988

Abstract:
The binning method of an image sensor includes reading out a plurality of pixel signals from at least two rows of each of a plurality of areas of a pixel array at a time, each of the plurality of areas including a plurality of pixels arranged in a 2n×2n matrix, where n is an integer equal to or greater than 2; generating first image data by performing analog-to-digital conversion on the plurality of pixel signals; generating, based on the first image data, a first summation value of each of a plurality of binning areas based on two pixel values corresponding to a same color in each of the plurality of binning areas, the plurality of binning areas corresponding to the plurality of areas of the pixel array; and generating a second summation value of each of two binning areas based on two first summation values corresponding to a same color in the two binning areas, the two binning areas being adjacent to each other in a column direction among the plurality of binning areas.
