    摘要: In a conventional liquid crystal display, for example, a grayscale display characteristic is changed by providing a plurality of grayscale voltage generation circuits which are selected by a selection circuit, which has resulted in a complicated circuit and consequently in a cost increase. A data conversion circuit 8 utilizing algorithm for performing arbitrary data conversion converts digital image data input from the outside and inputs the resultant data to driving circuits 3 through a control signal generation circuit 1. The source driving circuits 3 select one of a plurality of grayscale voltages generated by the grayscale voltage generation circuit 2 based on the converted digital image data and outputs the same to source lines, thereby changing the grayscale display characteristic.

    摘要: A matrix display panel has scan lines that are selected in consecutive order. An interlaced image signal is displayed by the use of one or more output enable signals that enable only every second selected scan line to be driven. A progressively scanned image signal having a frame rate too high to be handled by the matrix display panel is displayed as an interlaced image, by use of the same output enable signals. Consequently, no frame memory is needed for scanning conversion or frame-rate conversion.

    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: 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 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.
