1. An image sensing device comprising:
a plurality of selectors suitable for generating a plurality of selected pixel signals corresponding to one of a plurality of pixel signals;
a plurality of signal converters suitable for:
setting a plurality of initial voltages which are different from one another, on the basis of a ramp signal and a plurality of initialization signals during an initialization period, and
generating a plurality of converted pixel signals to which the plurality of initial voltages are respectively reflected, on the basis of the plurality of selected pixel signals and the ramp signal during a readout period; and
a calculation circuit suitable for averaging the plurality of converted pixel signals.
