1. An imaging device comprising:
a pre-processing module configured to generate a first image by performing a binning operation based on a raw image in a first mode and to generate a second image by performing a remosaic operation based on the raw image in a second mode;
a calibration module configured to generate calibration data based on a first image associated with a first raw image and a second image associated with a second raw image, the calibration data including a code level difference of the first image and the second image for each of a plurality of colors by a grid unit; and
a compensation module configured to receive a second image associated with a third raw image, to generate a calibration image by decoding the calibration data, and to generate a compensated second image associated with the third raw image by summing the second image associated with the third raw image and the calibration image to compensate for a color tone difference between the first mode and the second mode by the grid unit,
wherein the calibration module is configured to compensate a code level difference due to the remosaic operation in the second mode by the grid unit, based on the calibration data, so that the color tone difference of a low-illuminance region of the second image associated with the third raw image is improved.
