摘要： Responsive to image data of three colors, six hue data are obtained, and then first comparison-result data and second-order terms each relating to one of the six hues, and second comparison-result data each relating to one of the six inter-hue areas are obtained. Matrix calculation is performed on the first comparison-result data, the second comparison-result data, and the second-order terms, using coefficients. By varying the coefficients, adjustment can be made to only the target hue or inter-hue area, without affecting other hues and inter-hue areas. Thus, the six hues and six inter-hue areas can be varied independently, and the large-capacity memory is not required. In addition, gray scale conversion is applied to the result of the matrix calculation, so as to compensate for the non-linearity of the output device.

摘要： In an image display device for receiving and displaying image data, color converter converts the image data on the basis of conversion characteristics data stored in a conversion characteristics storage. The conversion characteristics designation means including means for designating the hue of the colors outputs the conversion characteristics designation data, and conversion characteristics setting means calculates the conversion characteristics data on the basis of the conversion characteristics designation data, and sets the conversion characteristics data in the conversion characteristics storage. The color converter comprises a calculation term generator for receiving the first image data, and outputting calculation terms which are effective just for the specific hues; and a matrix calculator performing matrix calculation using the calculation terms effective just for the specific hues. The user can adjust just the hue of the desired color. Real-time processing of moving pictures can be achieved without placing a heavy load on a CPU. The image after the adjustment can be displayed on a real-time basis.

By varying the coefficients, adjustment can be made to only the target hue or inter-hue area, without affecting other hues and inter-hue areas. Thus, the six hues and six inter-hue areas can be varied independently, and the large-capacity memory is not required.
