1. An image sensing device comprising:
an analyzer suitable for analyzing a state of each of multiple kernels based on an analog gain value and a plurality of pixel values;
a detector suitable for detecting color noise of a target pixel value among pixel values included in a target kernel among the multiple kernels, according to the analysis result of the analyzer; and
a corrector suitable for correcting the target pixel value according to the detection result of the detector.
