ABSTRACT:
The present invention discloses an image display device, comprising: a lookup table specifying a corresponding relationship between color saturation represented by gradation and set values associated with part including the minimum value of the color saturation; a first color saturation setting unit for setting color saturation associated with the set value greater than or equal to a predetermined value based on the lookup table; and a second color saturation setting unit for setting color saturation associated with the set value less than the predetermined value by calculating values which gradually decreased to the minimum value of the color saturation as the set value decreases.
