Abstract
In a method of color decomposition, inter-color images indicating similarity between color sensitivities are generated based on color images. Conversion coefficients of the color images and the inter-color images with respect to a white image are determined. A pseudo-white image corresponding to the color images and the inter-color images is generated using the conversion coefficients the pseudo-white image similar to a real white image is generated using the inter-color images indicating similarity between color sensitivities. Deep learning of the artificial neural network is performed efficiently using the color images and the pseudo-white image and the demosaiced images of high quality are generated using the trained artificial neural network that is trained.
