Original Abstract Submitted

An image sensing device includes a pixel array including a plurality of unit pixels, and a driving unit configured to drive each unit pixel of the plurality of unit pixels. Each unit pixel comprises: a first region including a first photodiode, a first floating diffusion region, and a second floating diffusion region, a second region including a second photodiode and a third floating diffusion region, and a floating diffusion (FD) connecting transistor connected to any one of the first floating diffusion region, the second floating diffusion region or the third floating diffusion region. The driving unit is configured to alternately perform a normal operation of individually operating the plurality of unit pixels, and a binning operation of grouping at least two unit pixels of the plurality of unit pixels and operating the at least two unit pixels simultaneously.
