Abstract
An image sensing device includes a first sampling circuit suitable for sampling a reference ramp signal as a ramp signal; a switching circuit suitable for sequentially outputting first and second pixel signals to a common node based on first and second control signals; a second sampling circuit suitable for sampling the first and second pixel signals, which are sequentially outputted through the common node, as a measurement signal; a comparison circuit suitable for comparing the ramp signal with the measurement signal and generating a comparison signal corresponding to a comparison result; and a count circuit suitable for generating a count signal, which corresponds to a voltage level of the measurement signal, based on the comparison signal and a clock signal.
