  • Patent number: 9196024
    Abstract: Embodiments of the present invention disclose a method and an apparatus for enhancing color, and relate to the image processing field, so as to solve a case of over enhancement on a region having high luminance in an original image which is caused after enhancement processing is performed. A specific solution is: obtaining a luminance component of a currently processed image; performing Gaussian filtering processing on the luminance component to obtain an illumination component; obtaining a first reflection component of the currently processed image according to the luminance component and the illumination component; performing enhancement adjustment on the first reflection component to obtain a second reflection component; obtaining a luminance gain according to the luminance component and the second reflection component; and performing enhancement processing on the currently processed image, to obtain a first enhanced image. The present invention is applicable to a process of color enhancement.
