摘要： Responsive to image data of three colors, six hue data are obtained, and then first comparison-result data 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, and the second comparison-result data, 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. The coefficients used for the matrix calculation are stored in a storage, which can be set and altered by the use of a setting unit.

摘要： After applying gray scale conversion 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. Moreover, by the use of the gray scale conversion, the effects of the non-linear characteristics of the input signals are removed.

摘要： A color conversion apparatus receives red-green-blue color data, calculates characteristic information and first hue region data from the color data, adjusts the first hue region data according to the characteristic information to obtain second to N-th hue region data, N being an integer equal to or greater than three, generates matrix coefficients for the second to N-th hue region data, and performs a matrix operation on the second to N-th hue region data to obtain color data with four or more color components. Color data with three primary components are thereby converted to color data with four or more primary components by simple calculations, without using a large amount of memory space.

摘要： An image data generator generates first image data consisting of a plurality of color data and being an image information for each pixel. An image processor including a color converter applies image processing such as color conversion on the first image data. An image display unit displays an image using image data consisting of second color data. An image data output unit outputs the first image data to the outside. The image display unit performs image display using the image data having received image-processing such as color conversion, while the image data output unit and outputs to the outside the image data before receiving the image processing. It is possible to obtain an image processing device capable of realizing an “exact color reproduction” or a “preferred color reproduction” on an image display image display unit, and outputting, to the outside, image data in the form of a standard image data, without reflecting the characteristics of the image display unit.

摘要： In an image processing device and image processing method in which first image data consisting of a plurality of color data and constituting image information for each pixel are input, and second image data consisting of a plurality of color data are calculated and output, after color conversion of the first image data, dither processing is applied to produce the second image data. As a result, information of the fractional part generated as a result of the color conversion is not omitted but preserved. Tone conversion may be performed after the color conversion, and before the dither processing. The image processing device or image processing method can restrain reduction in the number of colors that can be expressed, and restrain the generation of discontinuities (irregularities) in the change of data, while realizing an “exact color reproduction” or “preferred color reproduction.”
