Classification: CPC G | IPC G

Claim 17:
18. A method of demosaicing images, comprising:
generating a green-blue image indicating similarity between green sensitivity and blue sensitivity and generating a green-red image indicating similarity between green sensitivity and red sensitivity, based on a red image, a green image, and a blue image;
determining conversion coefficients of the red image, the green image, the blue image, the green-blue image, and the green-red image with respect to a white image;
generating a pseudo-white image corresponding to the red image, the green image, the blue image, the green-blue image, and the green-red image using the conversion coefficients;
generating training mosaic images based on the red image, the green image, the blue image, and the pseudo-white image;
training an artificial neural network based on the training mosaic images; and
generating demosaiced color images corresponding to input mosaic images based on the artificial neural network that is trained.
