An image sensor is provided. An image sensor can include a plurality of unit pixels. Each of the unit pixels can include a photoelectric converter as a light receiving element. In each unit pixel, a transport switching unit can transport charges in the photoelectric converter to a floating diffusion region, and a first switching unit can selectively connect the floating diffusion region to a first sensing line. A second switching unit can selectively connect the floating diffusion region to a second sensing line, and a first sensing part can be connected to the first sensing line, and a second sensing part can be connected to the second sensing line.
