摘要： There is disclosed a display device using a color wheel having a color filter Cw, in addition to normal color filters corresponding to the three primary colors. The filter Cw has almost flat spectral transmission characteristics. Brightness information included in a color image signal is quantized with (n+m) bits. Information corresponding to the lower-order n bits is displayed by light transmitted through the filter Cw. Information corresponding to the upper-order n bits is displayed by light transmitted through the normal color filters. Only brightness information to which the human eye is visually sensitive is reproduced by the filter Cw having a lower transmissivity. This can eliminate a lack of the number of gray levels due to a constraint on the minimum switching speed of a light valve. Furthermore, the brightness little deteriorates.

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： In an on screen display apparatus and an on-screen display method, the number of scanning lines of an input signal is detected. In accordance with the result of the detection, a vertical dot number of a character to be displayed is determined and font data is read from a memory device after adjusting a dot number of a blank portion of the font data. Hence, even if the number of the scanning lines changes, the number and positions of characters displayed in one screen remain constant.

摘要： A projection display uses a light modulating device to modulate, in accordance with image data, light radiated from a light source, project the modulated light onto a screen, and display an image. The projection display separates a unit of time configuring the image data into an effective light time when the light modulating device can express the light as an image on the screen and an ineffective light time when the light modulating device cannot express the light as an image on the screen. The projection display increases the power supplied to the light source during the effective light time over the power supplied to the light source during the ineffective light time.

摘要： An image signal representing consecutive video frames is resampled, using different sampling phases so that different subsets of pixels are taken from each frame in a consecutive set of frames. The resulting set of resampled frames is combined into a single frame and transferred to an image display unit that divides the single frame into subframes and displays the subframes sequentially with different pixel shifts. Each pixel in each subframe is displayed at its correct spatial and temporal position. Although the resampling process greatly reduces the pixel data transfer rate, the image display unit can reproduce still images without loss of definition and moving images without motion blur.
