摘要： An apparatus for adjusting image color saturation and a method for adjusting a saturation level of an original image data are provided. The image color saturation apparatus includes a first color over-saturation level calculating unit, a parameter adjusting unit, a saturation adjusting unit and a second color over-saturation level calculating unit. The apparatus for adjusting image color saturation detects the number of over-saturation pixels in an input image according to a predefined over-saturation area, and the number of over-saturation pixels in an adjusted output image. Thus, the parameter adjusting unit can dynamically adjust a saturation gain to maintain the frame consistency according to the number of the over-saturation pixels.
