PURPOSE: An image sensor is provided to increase the sensitivity of a lower luminance. CONSTITUTION: A first transmission switch(108) transmits the stored photocharge of PD(Photo Diode) to a first floating diffusion node. According to the second transmission signal, a second transmission switch(110) transmits the photocharge which is stored in the PD to a second floating diffusion node. According to the sensitivity signal, a sensitivity control switch(100) selectively controls the connection between the first floating diffusion node and the second floating diffusion node. A driving transistor(104) converts an electrical charge which is sanctioned to the second diffusion node into an electrical signal.
