Abstract
A method and apparatus for combining colorants using a camera. The method of combining colorants using a camera includes extracting color data from an image of an object captured using a camera, converting the color data into spectral reflection factor data of the object on the basis of a pre-constructed camera color model, acquiring spectral reflection factor data for an estimated colorant combination obtained by simulating a combination of colorant samples obtained from a colorant database, and selecting an optimal colorant combination by comparing errors between the spectral reflection factor data of the object and the spectral reflection factor data for the estimated colorant combination. Therefore, it is possible to use a highly accessible and inexpensive camera, such as a smartphone camera, and thus an ordinary user can easily find an optimal colorant combination.
