    摘要: A color conversion apparatus receives first image data including first red-green-blue color data in which the possible values of the red, green, and blue components extend beyond the range from 0% to 100%. The first color data are analyzed into first hue region data, the magnitudes of which are adjusted according to the brightness and/or saturation of the first color data to obtain second and third hue region data. The gamut of colors of the first image data is detected, and matrix coefficients are generated according to the detected gamut. The matrix coefficients are used to perform a matrix operation on the second and third hue region data to obtain second color data, thereby converting the first image data to second image data with conversion characteristics appropriate for the gamut of colors of the first image data.

    摘要: A video display apparatus generates luminance information for individual frames of a video signal from histograms of the luminance component of the video signal, and classifies the content of the video signal on the basis of this information. Color saturation information is also generated from color saturation histograms, and scene changes are detected. Video correction parameters and display control parameters are derived from the content classification and color saturation information. The video signal is corrected according to the video correction parameters, and displayed according to the display control parameters. Display characteristics suitable for the video content are thereby obtained. The parameters are changed when a scene change is detected, so that the viewer is not disturbed by the change in video display characteristics.

    摘要: A light diffusion element includes a light diffusion layer that contains at least two types of liquid crystal molecules each having a different light scattering characteristic defined by a voltage and a refractive index. A pair of electrodes sandwiches the light diffusion layer, an applying unit generates and applies a variable voltage to the pair of electrodes, and a voltage changing unit varies the voltage generated by the applying unit. The voltage changing unit varies the voltage such that each of the refractive indexes of the liquid crystal molecules in the light diffusion layer changes temporally.

    摘要: A field sequential color display is obtained by successive display of a sequence of monochromatic images. Each monochromatic image is displayed with light occupying a different wavelength region, but one of the wavelength regions includes part or all of another one of the wavelength regions. These two wavelength regions are used to display one of the original primary colors of the color image, the included or partially included wavelength region being used for comparatively low gray levels and both wavelength regions being used for comparatively high gray levels. This scheme provides a way to increase the number of gray levels that can be displayed following a gamma correction, as well as broadening the gamut of reproducible colors.

    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 intermediate image generating means (1) generates a horizontal intermediate image (D1h) and a vertical intermediate image (D1v) by extracting components of an input image (DIN) in a particular frequency band; an intermediate image processing means (2) generates a horizontal image (D2Bh) and a vertical image (D2Bv) by performing non-linear processing (2A) and high-frequency component generation (2B); an intermediate image (D2) is obtained by combining these horizontal and vertical images by performing weighted addition for each pixel and is added (3) to the input image (DIN) to obtain an enhanced output image (DOUT). Even if the input image includes a fold-over component on the high-frequency side or does not include an adequate high-frequency component, adequate image enhancement processing can be carried out.
