Claim 10:
11. An image sensor comprising:
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;
a fourth pixel configured to include a first floating diffusion region and a second floating diffusion region,
wherein a first floating diffusion region of respective pixels and a second floating diffusion region of the respective pixels are electrically connected in response to a first conversion gain signal, and the second floating diffusion region of the respective pixel and a third floating diffusion region of the respective pixels are electrically connected in response to a second conversion gain signal,
wherein the third floating diffusion region of the respective pixel is connected to a power terminal in response to a reset gate signal, and
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.
