摘要： A block noise reducer detects block boundaries in all components of an input video signal and smoothes the different components selectively on the basis of the detected block boundaries and their periodic locations. By removing block noise on the basis of block boundaries detected in color difference signals, the block noise reducer removes block noise from scenes with gradual changes in color but little or no change in luminance.

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 method and apparatus for converting color includes converting the hue, lightness, and/or saturation of first color data representing each of plurality of colors forming a color image, to produce second color data corresponding to the first color data. The second color data is converted to third color data suitable for the color space which can be expressed by the image output device used for the output of the color image. Color contraction which is conventionally associated with color conversion that increases lightness or saturation can be prevented.

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： By changing coefficients of second-order and first-order calculation terms relating to respective hues, and first-order calculation terms in the form of comparison-result data relating to respective inter-hue areas, only the target hue or inter-hue area among the six hues of red, blue, green, yellow, cyan, and magenta, and the six inter-hue areas can be varied, without affecting other hues and inter-hue areas. Thus, the six hues and six inter-hue areas can be corrected independently, and the large-capacity memory is not required.
