Abstract
In an image sensor including a pixel array having a plurality of pixels, each of the plurality of pixels includes: a first photodiode; a second photodiode having a larger light-receiving area than the first photodiode; a first floating diffusion node where charge generated in the first photodiode is accumulated; a second floating diffusion node where charge generated in the second photodiode is accumulated; a first capacitor accumulating charge overflowing from the first photodiode; a first driving transistor configured to generate an output signal corresponding to a voltage of the second floating diffusion node; and a second capacitor storing an amount of overflow charges according to an overflow operation for accumulating the overflowing charge and storing an amount of reset charges according to a reset operation for resetting the first floating diffusion node.
