Apparatus and method for adjusting saturation of color image |
摘要 |
An apparatus and method for adjusting the saturation of a color image are provided. In the saturation adjusting apparatus and method, a saturation value for each of pixels of an input image is calculated, and a peak saturation value and a mean saturation value of the input image are calculated using the saturation values of the pixels. A peak gain value based on the peak saturation value and a mean gain based on the mean saturation value are calculated. A local gain value is calculated using the mean gain value and the saturation values of the pixels. A pattern gain value for a test pattern image and a color gain value for a skin color image are also considered to adaptively adjust the saturation of the input image. <IMAGE>
