摘要： A tone display method for displaying a tone of an image in a display system which divides a time width of a field of an image signal into a plurality of weighted subfields and controls operation of the subfields. The tone display method includes the steps of coding the image signal in the plurality of weighted subfields the plurality of weighted subfields including a plurality of most significant subfields having respective weights which are substantially equal to one another, and a plurality of less significant subfields having respective weights each of which is less than each of the weights of the most significant subfields, a sum of all of the weights of the less significant subfields being greater than each of the weights of the most significant subfields, the coding being chosen from a plurality of codings all representing substantially a same tone level when a tone level of the image signal is not less than each of the weights of the most significant subfields, and displaying the image signal coded with the chosen coding.

摘要： A video processing system is described for providing an image having more than one region on a display (DISPLAY). The system has a control means which can determine, for each region, the type (e.g., graphics, text, computer programs, broadcast TV video, etc.) of the image material being displayed in the region. The system also has a video driver coupled to the display for providing image signals having contrast and brightness characteristics. The control means generates a control signal for causing said video driver means to adjust said contrast and brightness characteristics of said image signals according to the type of material being displayed in said region.

摘要： A false contour correcting apparatus is capable of removing a false contour in an image based on a digital image signal while avoiding such a side effect caused by false contour correction where noises negatively effecting the display occur on a screen. Therefore, in the false contour correcting apparatus according, a double bit change detection circuit detects as a double bit change a signal value change which is twice a minimum quantization unit in a digital image signal, and outputs a double bit change detection signal representing the position of the double bit change. A signal correction circuit corrects the double bit change in the digital image signal into two one-bit changes on the basis of the double bit change detection signal. Consequently, a false contour corresponding to a portion where the double bit change exists is removed.

摘要： Plasma Display Panels (PDP) are becoming more and more interesting for TV technology. Due to the larger size of PDPs, with larger viewing angle the large area flicker effect will become more serious in the future, in particular when handling 50 Hz video standards. This invention proposes a different sub-field organisation, with different coding, which reduces large area flicker artefact, and which includes grouping of sub-fields in two sub-field groups wherein the two sub-field groups are identical in terms of the most significant sub-fields and different in terms of the least significant sub-fields, and a sub-field coding process that distributes luminance weight symmetrically over the two sub-field groups so as to minimize the large area flicker luminance component.

摘要： There is provided a device for controlling the brightness of a monitor screen to prevent the edge of the screen from appearing darker than the center of the screen by setting a black level signal scanned to the edge of the screen to be greater than a black level signal scanned to the center of the screen. The device includes a parabolic signal generator for generating a parabolic signal. A video output signal generator receives a video input signal in which an image is carried on a black level signal voltage and a brightness control voltage for controlling the brightness of the screen. The video output signal generator generates a first video output signal having a black level signal adjusted by the brightness control voltage. A signal synthesizer receives the first video output signal and the parabolic signal and generates therefrom a second video output signal in which the parabolic signal is added to the first video output signal.
