    摘要: The automatic cut-off system includes a video data processing circuit, a cut-off control circuit, a drive circuit, and a level control section. The video data processing circuit adds a cut-off reference pulse having a predetermined level to primary-color signals of red (R), green (G) and blue (B) at different timings within a single vertical blanking interval, and outputs latch timing signals respectively indicating the timings. The cut-off control circuit shifts a level of each primary-color signal having the cut-off reference pulse added thereto based on a corresponding cut-off control signal. The drive circuit drives each cathode of a CRT (cathode-ray tube) based on a corresponding one of the shifted primary-color signals, and outputs a voltage corresponding to each cathode current as a common feedback signal. The level control section latches the feedback signal in response to each latch timing signal, and outputs the cut-off control signal of one of the primary-color signals.

    摘要: In a horizontal deflection circuit, a waveform response of a horizontal output pulse must be adequately taken into account before and after a switching of the horizontal output pulse so that the waveform does not lack in shape and does not lose continuity at the switching. A switching apparatus for a horizontal driving apparatus includes (a) a horizontal driving pulse generator which generates a horizontal driving pulse from a horizontal synchronization signal, (b) an alternative signal generator which outputs an alternative signal different from the horizontal driving pulse, (c) a horizontal output control device which determines a timing to switch between the horizontal driving pulse and the alternative signal, and (d) a switching device which switches an output pulse with a control signal which is output from the horizontal output control device. The switching device switches only when both the output signal from the horizontal driving pulse generator and the output signal from the alternative signal generator change from a low level to a high level at the same time.

    摘要: The tone of video signals is corrected without degrading the tone of certain image features, such as a human face. A gain controller operates and outputs an adjustment value using a histogram output produced by a histogram generator. An average value of picture levels on a screen is detected by an average picture level detector. A histogram correction circuit calculates a look-up table, and a video signal correction circuit corrects the tone of the video signals using the look-up table.

    摘要: A histogram generator creates a histogram to detect the characteristics of video signals. The histogram generator allows for a reduction in problems of instability caused by noise that may exist in other histogram generators. A width is allocated to thresholds used in creating the histogram, and signal values are counted after weighting those falling near a threshold.

    摘要: A skin-color-area detector generates a skin-color-area signal from an input video signal. An average luminance level detector generates an average luminance level signal from a luminance signal. These signals are transmitted to a skin-color-corrector to generate skin-color-correction signals. At a saturation controller and at a luminance signal corrector which each receive the skin color corrections signals, skin-color is optimumly corrected. Thereby reproduction quality of skin-color signals in video signals is enhanced.

    摘要: An automatic auction method which makes it unnecessary for bidders to stay before auction terminals at the time of auction and which makes possible auction transactions on an open network on which it is difficult to assure the on-line and real time properties. A plurality of auction ordering information pieces each containing a desired price, number of purchase, and a highest possible price in competition for the desired price and received from bidder terminals via on-line circuits are collected. Until an auction issue appears, the price is lowered. If there is at least one auction issue and a desired quantity which is the sum total of the numbers of purchase of the auction issues is not satisfied, then it is determined whether there is an auction issue coinciding in price by comparing the set price with (the desired price+the highest possible price in competition). Until the desired quantity is satisfied, the price is raised.

    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.
