Abstract
An image sensing device capable of generating a high dynamic range (HDR) image is disclosed. The image sensing device includes a pixel and a compensation circuit. The pixel configured to output to a sensing node, a sensing voltage corresponding to a voltage of a floating diffusion region, which is included therein and has first and second capacitances in respective first and second modes, the second capacitance being greater than the first capacitance. The compensation circuit controls, in a first section, an offset voltage level of the sensing node through a first path and boosts, in a second section, the sensing voltage through a second path.
