Abstract:
1. A color saturation adjusting apparatus used for a display system, comprising: an RGB-HSV conversion unit receiving an input RGB image signal and converting RGB values of the input RGB image signal into corresponding HSV values; a color saturation adjusting function setting unit setting a color saturation adjusting function in response to an input of a user; a color saturation adjusting unit generating new HSV values in which color saturation values are varied from color saturation values of the corresponding HSV values based on the color saturation adjusting function; and an HSV-RGB conversion unit converting the new HSV values generated by the color saturation adjusting unit into corresponding RGB values and outputting the corresponding RGB values, wherein a plurality of color saturation adjusting values corresponding to a plurality of representative hues are input by the user and other color saturation adjusting values corresponding to intermediate hues between the representative hues are obtained by interpolating the color saturation adjusting values of the representative hues by using an interpolation function.
