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 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 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： In an image displaying apparatus, first and second detecting units detect quantities of light propagating through a light path at two different locations. A variation calculating unit calculates the variation in the light quantity in the light path based on the quantities of light detected by each of the first and second detecting units. A controlling unit controls the quantity of light propagated to the screen if the variation in the light quantity exceeds a predetermined value.
