Claim 7:
8. An operation method of an imaging device that includes an image sensor and an image signal processor, the image sensor including a pre-processing module, and the image signal processor including a calibration module and a compensation module, the method comprising:
receiving, by the pre-processing module, a first raw image; and
performing, by the pre-processing module, a remosaic operation on the first raw image to generate a second image associated with the first raw image, wherein a resolution of the second image associated with the first raw image is identical to a resolution of the first raw image;
receiving, by the compensation module, a second image associated with a first raw image;
loading, by the compensation module, calibration data, the calibration data including a code level difference of a first image and a second image for each of a plurality of colors by grid units;
decoding, by the compensation module, the calibration data to generate a calibration image; and
summing, by the compensation module, the second image associated with the first raw image and the calibration image to generate a compensated second image associated with the first raw image so that a color tone difference between a first mode and a second mode is compensated by the grid units.
