    • An apparatus and method of enhancing color of image is provided. The apparatus for enhancing color of image including: a saturation enhancement unit to enhance a saturation of an input image using a saturation variation according to a brightness feature of the input image; a gray scale area protection unit to determine a final saturation variation depending on a saturation value of the input image and the saturation variation, and to prevent a saturation enhancement of a gray scale area; a color control unit to control a color of the input image using a color variation according to the brightness feature of the input image; and a brightness value correction unit to correct a difference between a resultant brightness value and an input brightness value of the input image, the resultant brightness value being generated by applying the final saturation variation and the color variation to the input image.
    • 提供了增强图像颜色的装置和方法。 用于增强图像颜色的装置包括:饱和度增强单元,用于根据输入图像的亮度特征,使用饱和度变化来增强输入图像的饱和度; 灰度区域保护单元,用于根据输入图像的饱和度和饱和度变化来确定最终饱和度变化,并且防止灰度区域的饱和度增强; 颜色控制单元,用于根据输入图像的亮度特征,使用颜色变化来控制输入图像的颜色; 以及亮度值校正单元,用于校正所得到的亮度值和输入图像的输入亮度值之间的差,所得到的亮度值是通过对输入图像应用最终饱和度变化和颜色变化而产生的。
