Claim 18:
19. An image sensing device comprising:
an image sensor including a pixel array suitable for generating a plurality of pixel values corresponding to a set frame; and
an image processor suitable for:
determining whether the frame has low illuminance;
when it is determined that the frame has the low illuminance, selecting pixel values corresponding to a target kernel among the frame;
determining whether the target kernel is a flat region and a low saturation region;
when it is determined that the target kernel is the flat region and the low saturation region, detecting whether a target pixel value of the target kernel corresponds to color noise based on other pixel values of the target kernel, which have other color channels different from a color channel of the target pixel value; and
when it is detected that the target kernel corresponds to the color noise, correcting the target pixel value using the other pixel values.
