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： A luminance information detector (3) detects a maximum luminance-signal gradation information value and a minimum luminance-signal gradation information value from one frame of a luminance signal obtained from an image signal (Db) and outputs the values as luminance information values (Yi). A color information detector (20) detects a maximum color-signal gradation information value of the three color signals (RGB) obtained from the image signal (Db) for one frame and a minimum color-signal gradation information value of the three color signals (RGB) obtained from the image signal (Db) for one frame and outputs the values as color information values (Ci). A correction controller (45) calculates parameters (Pa) based on the luminance information value (Yi) and the color information values (Ci); a gradation corrector (5) processes negative color signals point-symmetrically with respect to the origin, according to the parameters (Pa), in the same way as it processes positive color signals. A display unit displays an image based on the image signal (Dc), which is the image signal (Db) after gradation-scale correction. Contrast can thereby be improved without excessive color collapse.

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.
