Abstract
An image sensor is provided. The image sensor includes a pixel array in which a plurality of pixels are arranged, wherein each of the plurality of pixels includes a photodiode; a floating diffusion node configured to integrate photocharges generated in the photodiode; a first sampling transistor electrically connected to a first node; a first capacitor electrically connected to a first node and configured to store a charge corresponding to a voltage of the floating diffusion node which is reset; a second sampling transistor electrically connected to a second node; a second capacitor electrically connected to the second node and configured to store a charge corresponding to a voltage of the floating diffusion node in which the photocharges are integrated; and at least one mode transistor configured to adjust an equivalent capacitance of each of the first node and the second node according to a mode control signal.
