摘要： In an image display which reproduces a color image by using lights color-separated into four or more colors through color filters, the objects of the invention are to effectively utilize the energy of light from a light source and to reduce the effect that a slight shift of the spectral transmittance characteristics of the color filters exerts on the spectral distributions of the lights after color separated. In an image display having a light source and four or more kinds of color filters and for color-separating light emitted from the light source into four or more colors through the four or more kinds of color filters and reproducing a color image by using the color-separated lights, the spectral transmittance characteristics of the color filters are set so that the cutoff wavelengths of the four or more kinds of color filters exist in a wavelength region in which the spectral distributions obtained by multiplying the spectral emissivity characteristic of the light emitted from the light source by the color matching functions are smaller than the values obtained by multiplying the average values of the spectral distributions in the wavelength region from 380 to 780 nm by an integer.

摘要： The invention relates to an image display device displaying color image and has its object to display image having a large contrast and excellent visibility to the viewer in an image display device particularly used under environment where external light exists.To achieve the above object, black-approximated data generating means 4 generates black-approximated data R3, G3, and B3 that are data related to chromaticity in displaying black on image display means 3. Black correction means 2A subtracts subtraction data R4, G4, and B4 that have the same value as the black-approximated data R3, G3, and B3, from after-input-processing image data R1, G1, and B1, thereby to calculate after-black-correction image data R2, G2, and B2. The image display means 3 emits in response to the values of the after-black-correction image data R2, G2, and B2, thereby to perform image display processing on a predetermined screen.

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.”

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.
