Claim 9:
10. The image sensing device of claim 6, wherein the signal conversion circuit includes a plurality of signal converters, each including:
a comparator suitable for comparing the ramp signal inputted through a positive input terminal thereof with a comparison pixel signal inputted through a negative input terminal thereof, and outputting a comparison signal, which corresponds to a result of the comparing, through an output terminal thereof;
a switch suitable for coupling the negative input terminal and the output terminal based on a corresponding initialization signal among the plurality of initialization signals; and
a capacitor coupled to the negative input terminal, and suitable for initializing the negative input terminal to a corresponding initial voltage during the initialization period, and generating the comparison pixel signal to which the corresponding initial voltage is reflected, by sampling a corresponding selected pixel signal during the readout period.
