Patent ID: 6901162

Claim:
An image display device for receiving an input image data comprising three or more color data, and displaying the input image data on an image display unit, comprising: a color converter for converting a first image data comprising three or more color data, into a second image data comprising three or more color data, on the basis of conversion characteristic data; a conversion characteristic storage for storing the conversion characteristic; conversion characteristic designation means for designating the conversion characteristic to be used in the color converter, and outputting corresponding conversion characteristic designation data; and conversion characteristic setting means for calculating the conversion characteristic data on the basis of the conversion characteristic designation data, and setting the conversion characteristic data in the conversion characteristic storage; wherein said color converter comprises: a calculation term generator for receiving the first image data, and outputting calculation terms which are effective just for specific hues; and a matrix calculator performing matrix calculation using the calculation terms effective just for the specific hues, wherein said conversion characteristic data includes matrix calculation coefficients used in said matrix calculator, and wherein said conversion characteristic setting means calculates the conversion characteristic data by adding or subtracting the value corresponding to the value of the conversion characteristic designation data to or from the coefficients among the coefficients for the calculation term effective for the selected color, among the calculation terms effective just for the specific hues.
