摘要： A field sequential color display is obtained by successive display of a sequence of monochrome images of different colors. Monochrome images in at least one of the colors are displayed with light of two different brightness levels, the light of the lower brightness being used to display comparatively low gray levels, the light of both the lower and higher brightness levels being used to display comparatively high gray levels. This scheme provides extra resolution at the low end of the gray scale, and increases the number of displayable gray levels by counteracting the loss of gray levels that occurs due to gamma correction.

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 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： An image processing apparatus enhances contrast without producing color balance distortion or color collapse by generating a gradation-scale correction table from a distribution of a characteristic quantity of an input image signal, using the gradation-scale correction table to derive a gradation correction parameter for each pixel from a maximum component value of the pixel, and multiplying all components of the pixel by the gradation correction parameter.

摘要： An image data processing apparatus receives trichromatic image data with values expressing red, green, and blue and generates information indicating the gamut of colors of the image data. The gamut information is obtained from maximum and minimum values, or values equivalent to the maximum and minimum values, pertaining to different color components during a prescribed time interval, and indicates the actual gamut of colors that appear during the prescribed time interval. The gamut information is appended to the image data, or output separately from the image data, for use in subsequent image processing.

摘要： A field-sequential display apparatus having a light source that emits light of different colors in different subframes of an image controls the spectral distribution of the light emitted in each subframe according to characteristics of the input image data, or to ambient conditions or other user-specified conditions. The input image data are processed so that image colors are displayed correctly despite changes in the spectral distribution of the light-source colors. This scheme enables the gamut of reproducible colors to be altered from frame to frame to provide an appropriate balance between brightness and color saturation in each frame, and to compensate for ambient lighting conditions.

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.
