    摘要: A process is provided for developing and converting a lookup table (hereinafter called a “LUT”) composed of only characteristic points of the characteristic of a color device and having a volume smaller than that of a multidimensional LUT into a multidimensional LUT by a table development process. Image data converting means uses the multidimensional LUT to convert input image data into output image data. Thus, an effect can be obtained in that a color management apparatus can be operated with only the LUT composed of only characteristic points of the characteristic of the device and having a small volume.

    摘要: An image having a large contrast and excellent visibility to the viewer is displayed on an image display device used in the presence of light. A black-display characteristic specifying means generates a black-display characteristic specifying data indicating the brightness of the external light reflected from the surface of an image display means, which is obtained by operating an external-light brightness specifying bar to be displayed on the image display means. A black-approximated data calculating means calculates, based on the black-display characteristic specifying data, a black-approximated data related to at least one of luminance, chromaticity and tristimulus values in displaying black with the image display means. On receipt of an image data and the black-approximated data, a black correction means calculates a black-corrected image data, and displays an image on the image display means based on the black-corrected image data.

    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.
