Abstract:
1. An image sensor including a plurality of unit pixels, each of the unit pixels comprising: a photoelectric converter as a light receiving element; a transport switching unit transporting charges in the photoelectric converter to a floating diffusion region; a first switching unit selectively connecting the floating diffusion region to a first sensing line; a second switching unit selectively connecting the floating diffusion region to a second sensing line; a first sensing part connected to the first sensing line and converting a photo-electrically converted analog signal, stored in the floating diffusion region, to a digital signal on the basis of a first offset value; and a second sensing part connected to the second sensing line and converting a photo electrically converted analog signal, stored in the floating diffusion region, to a digital signal on the basis of a second offset value; wherein the first sensing part and the second sensing part perform data processing on charge information obtained from a first row of pixels during a first integration period and a second row of pixels during a second integration period at a predetermined timing, and the first and second rows of pixels have different exposure times.
