1. A method of color decomposition, comprising:
generating inter-color images indicating similarity between color sensitivities based on color images;
determining conversion coefficients of the color images and the inter-color images with respect to a white image; and
generating a pseudo-white image corresponding to the color images and the inter-color images using the conversion coefficients; wherein
the color images include a red image, a green image, and a blue image, and
the inter-color images include a green-blue image indicating similarity between green sensitivity and blue sensitivity, and a green-red image indicating similarity between green sensitivity and red sensitivity.
