1. An optimization method performed by an electronic apparatus, the optimization method comprising:
determining first information related to a) a difference between filter spectrum information representing a color filter spectrum and spectrum information representing a color spectrum in a preset color space or b) a difference between an image transformed by a color transformation matrix and a ground truth (GT) image in the preset color space;
determining second information representing smoothness of the color filter spectrum;
determining third information representing a transmittance of the color filter spectrum;
calculating a cost value based on the first information, the second information, and the third information;
comparing the calculated cost value and a threshold; and
in response to the calculated cost value being equal to or greater than the threshold, updating one of the filter spectrum information and the color transformation matrix.
