Claim 5:
6. An image sensing device comprising:
a pixel array suitable for generating a plurality of pixel signals;
a selection circuit suitable for generating a plurality of selected pixel signals through a plurality of selection lines by allowing the plurality of pixel signals to correspond one-to-one to the plurality of selection lines in a first mode, and generating the plurality of selected pixel signals through the plurality of selection lines by allowing at least one of the plurality of pixel signals correspond one-to-many to the plurality of selection lines in a second mode;
a signal conversion circuit suitable for setting a plurality of initial voltages 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.
