In addition, when an image having an aspect ratio of 4:3 is compressed in a horizontal direction to be displayed on a display screen having an aspect ratio of 16:9, a gray scale signal is inserted into a right edge and a left edge of an image signal and a brightness level of the inserted gray scale signal is made to correspond to an average brightness level of the image signal. Accordingly, a boundary line between a video image area and a non-video image area due to the difference in luminous characteristics of phosphors becomes hardly recognizable.

Abstract: An image display in which occurrence of beat noise can be suppressed without adding noise to an image in a pixel converting process is provided. The frequency of a data clock is preset to a value at which beat noise is not apt to occur (a value such that one of the dot clock frequency of the input analog video signal and the frequency of the data clock is not equal to or close to an integral multiple of the other) for each kind of the input analog video signal and is stored as a frequency correspondence list in a memory MM. In accordance with the kind of the input analog video signal, a control block 4 selects the set frequency of the data clock and allows a data clock generating block 6 to generate a data clock Cd. Consequently, at the time of a pixel converting process performed by a signal processing block 5, without adding noise to an image, occurrence of beat noise is suppressed.

Abstract: This invention relates to a device for converting bit strings from a first resolution to a second resolution suitable for application, in particular, on peripherals such as printers, scanners or facsimile machines. The device comprises a source register 31 in which a string of bits to be converted is stored by a CPU 11, a destination register 32 from which the CPU 11 extracts the converted string, and a pair of control registers 21 and 22 which cooperate for converting bit by bit the bit strings from the source register 31 to the destination register 32. The control registers 21 and 22, the source register 31 and the destination register 32 operate independently from the CPU 11 used and at a clock rate (clk2) greater than that (clk1) of the CPU 11, thereby permitting extremely fast conversion times.

Abstract: In an active matrix liquid crystal display, pixels are arranged in rows and columns of a matrix and are controllable via row electrodes and column electrodes. To improve and to expand the possibilities of image rendering without increasing the number of rows and columns to be controlled, the pixels are divided into sub-pixels with corresponding sub-pixel electrodes, each of which is connected to the column electrode assigned to the pixel via controllable switches. On the control side, the controllable switches are connected to the row electrode assigned to the pixel via pixel control unit which is common to them. From a control signal supplied to it via the row electrode the pixel control unit generates locally and chronologically different turn-on signals for the various switches so that they switch chronologically successive different gray-scale levels of a gray-scale signal present at the column electrode through to the sub-pixel electrodes.

Abstract: A graphics processor displays pixels in an image at non-uniform resolution, using a maximum resolution in the interior of a surface in the image, and a lower resolution at edges. Higher color resolution in the interior eliminates color aliasing that would otherwise be caused if the interior were displayed at the lower resolution. Lower resolution at the edges is not noticeable to the human eye, and allows the graphics processor to use one or more low resolution color signals in generating the displayed image, thereby reducing hardware (e.g. memory locations required to store such signals, and lines required to route such signals). One such processor (not necessarily a graphics processor) includes a resolution reducer and a resolution enhancer that respectively reduce and enhance the resolution of a signal. Specifically, the resolution reducer reduces the resolution of a high resolution signal to generate a low resolution signal.

Abstract: An image collaboration system conducts resolution independent image collaboration among a host computer and participating client computers. The subject of the image collaboration involves at least one source image. The source image is transformed into a hierarchical representation, such that each level of the hierarchical representation is sufficient to reconstruct the source image at a given resolution. The host computer displays, at a first resolution, an image based on one or more of the source images. To conduct the resolution independent image collaboration, the host computer generates a resolution independent description of the image, which describes the first display image relative to the source image, and broadcasts the resolution independent description of the image to the participating clients. In response, the participating clients generate an image from the resolution independent description of the image at the host computer at a resolution sufficient for display at the participating clients.

A calculation coefficient selector selects the calculation coefficients corresponding to the pattern thus decided, and outputs the selected coefficients to a calculator. Then the calculator calculates new pixel data by the use of such calculation coefficients and pixel data inputted thereto. In this apparatus, the post-conversion image formed by converting the number of its pixels can be displayed clearly.

Abstract: A matrix display device comprises a matrix display (10) with picture elements (18) arranged in a number of display lines (R). A driving circuit (3) supplies picture signals (Ds) to the picture elements (18) dependent on a video signal (V) which comprises, in a field (Fp), a number of video lines which is lower than the number of display lines (R).

In at least one of the line periods (Tl), at least two select periods (Tr) occur.
