    Abstract: Disclosed is an image sensor that includes a pixel array including first pixels sharing a first floating diffusion region and second pixels sharing a second floating diffusion region, a first analog-to-digital converter, a second analog-to-digital converter, and a switch circuit. In a first mode, the first analog-to-digital converter processes the first pixels, and the second analog-to-digital converter processes the second pixels. In the second mode, the first analog-to-digital converter processes a first image component of a pixel signal of the first pixels, and the second analog-to-digital converter processes a second image component of the pixel signal of the first pixels. An HDR image is implemented based on processing results of the first analog-to-digital converter and the second analog-to-digital converter.
