Claim 14:
15. An operation method of an imaging device, the method comprising:
receiving, by a calibration module, a first image associated with a first raw image and a second image associated with a second raw image;
generating, by the calibration module, a plurality of calibration data based on the first image associated with the first raw image and the second image associated with the second raw image, the plurality of calibration data including a code level difference of the first image associated with the first raw image and the second image associated with the second raw image for each of a plurality of colors by a grid unit;
storing, by the calibration module, the plurality of calibration data in a memory;
receiving, by a compensation module, a second image associated with a third raw image provided from a pre-processing module;
loading, by the compensation module, the plurality of calibration data stored in the memory;
decoding the plurality of calibration data to generate a calibration image; and
generating a compensated second image associated with the third raw image so that a color tone difference between a first mode and a second mode is compensated by the grid unit, based on the calibration image and the second image associated with the third raw image,
wherein said generating the plurality of calibration data comprises:
calculating first sub-grid data associated with a first sub-grid among a plurality of first grids of the first image associated with the first raw image;
calculating second sub-grid data associated with a second sub-grid among a plurality of second grids of the second image associated with the second raw image; and
generating first calibration data among the plurality of calibration data based on the first sub-grid data and the second sub-grid data.
