A solid-state image sensing device includes a pixel unit, analog-to-digital converter, controller, and adder. In the pixel unit, cells are two-dimensionally arranged on a semiconductor substrate. An output analog signal from the pixel unit is converted into a digital signal by the analog-to-digital converter and output. The controller controls the pixel unit and analog-to-digital converter, and causes the analog-to-digital converter to digitize a plurality of analog signals different in storage time in the pixel unit during the storage period of the electric charge of one frame. The adder adds digital signals corresponding to the analog signals different in storage time and output from the analog-to-digital converter.
