PURPOSE: A device for locally converting color gamut in hue, saturation and value(HSV) color space is provided to convert a local color region in a linear HSV color space, in which the color gamut is mapped, from a three dimensional color space to a different color region. CONSTITUTION: A color gamut conversion unit(600) maps linear HSV signal which is input from HSV conversion unit to a pre-set color conversion function. The color gamut conversion unit obtains a color conversion quantity. The obtained color conversion quantity is calculated by the linear HSV signal. A specific color gamut which corresponds to a color conversion region is converted to a different color region. A red, green and blue(RGB) reverse conversion unit(700) converts the linear HSV signal to RGB signal which is control signal for a linear display.
