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.

Abstract: An imaging system for generating a high dynamic range (HDR) image includes a pixel array that includes first pixels and second pixels, a driver circuit configured to control the first pixels based on a first exposure time and control the second pixels based on a second exposure time, an output circuit configured to output first pixel values of the first pixels and second pixel values of the second pixels from the pixel array, and a processing device configured to generate the HDR image based on a first Bayer image and a second Bayer image, where the first Bayer image is generated based on the first pixel values and the second Bayer image is generated based on the second pixel values and third pixel values of the first Bayer image. The quantity of pixels of the first pixels may be greater than the quantity of pixels of the second pixels.
