Claim 14:
15. An operating method of an image sensor having a pixel group configured to include a first pixel configured to include a first floating diffusion region and a second floating diffusion region; a second pixel configured to include a first floating diffusion region, a second floating diffusion region, and a third floating diffusion region; a third pixel configured to include a first floating diffusion region, a second floating diffusion region, and a third floating diffusion region; and a fourth pixel configured to include a first floating diffusion regional and a second floating diffusion region, the method comprising:
converting a size of a floating diffusion area of the pixel group according to an operation mode;
acquiring a reference signal using the converted floating diffusion area; and
acquiring a pixel signal using the converted floating diffusion area,
wherein the second floating diffusion region of the first pixel and the second floating diffusion region of the second pixel are directly connected by a first metal line without an intermediate transistor, the third floating diffusion region of the second pixel and the third floating diffusion region of the third pixel are directly connected by a second metal line without an intermediate transistor, and the second floating diffusion region of the third pixel and the second floating diffusion region of the fourth pixel are directly connected by a third metal line without an intermediate transistor.
