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： An image is processed by detecting pixel-to-pixel variations in brightness level, generating high spatial frequency information related to the variations, setting interpolation points with a spacing that varies according to the high spatial frequency information, and generating new pixels by interpolation at the interpolation points. By increasing the zoom ratio in one part and reducing the zoom in another part of each edge in a continuous manner, this method can mitigate edge degradation when an image is enlarged or reduced, without introducing discontinuities or other image artifacts. It also provides a convenient way to adjust edge sharpness in an image.

摘要： An image display device detects mutually adjacent bright and dark parts of an image and detects fine bright lines in the image. Bright parts of the image that are not fine bright lines are smoothed if they are adjacent to dark parts. This smoothing scheme improves the visibility of dark features on bright backgrounds without impairing the visibility of fine bright lines on dark backgrounds.

摘要： A tone step detector detects whether the tone of n-bit input image data varies gradually, and generates a tone processing control signal indicating that a tone step is contained. A bit shifter bit-shifts the n-bit input image data to the left by α bits, to generate (n+α)-bit image data. A tone processor smoothes the image data of the (n+α)-bit image data generated by the bit shifter, in the region where the tone processing control signal indicates that a tone step is contained, to generate (n+α)-bit image data having been smoothed in the above-mentioned region. Because of the selective smoothing, degradation in the image quality due to quantization is reduced even when an analog image signal whose tone varies gradually is input.

摘要： An image signal generating unit supplies a single image signal to multiple image display units having different unit numbers. Embedded in the image signal is an index signal designating the image display units on which the image signal is to be displayed. Each image display unit compares its unit number with the index signal to select displayable frames of the image signal, preferably storing and displaying the most recent selected frame. Each image display unit can thereby display a different image. The image signal may have a standard format.

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.
