摘要:
An image compensating apparatus includes an input unit to receive input of an photo image, a Gaussian filtering unit to perform Gaussian filtering on the photo image, a division-map generating unit to convert the photo image on which the Gaussian filtering is performed into a color space including a plurality of color components and then generating a chromaticity division-map based on a color coordinate value in the color space, a calculating unit to calculate average chromaticity of each respective region by using the chromaticity division-map, and a compensating unit to compensate chromaticity of each respective region of the photo image by using the average chromaticity of each respective region. Accordingly, a faded image input to the input unit may effectively be compensated.
