    摘要: An automatic chrominance control and color killer circuit for use in a color television receiver having a gain controllable chrominance amplifier for selectively amplifying chrominance signals and a color burst signal transmitted with a composite television signal during a color television transmission. The circuit further has a burst level detector connected to the chrominance amplifier, a control circuit including a time constant circuit connected to the burst level detector for deriving a control signal, which is supplied to the chrominance amplifier for controlling the gain thereof in response to the level of the control signal during the presence of the burst signal and for activating and inactivating the chrominance amplifier when the level of the control signal goes over and below a predetermined level, and a circuit connected between the burst level detector and the time constant circuit for shortening the time constant of the latter when the level of an output signal of the former goes below a predetermined level.

    摘要: For improving the frequency characteristic of a color television signal, particularly one in which the chrominance component thereof is provided with a bandwidth substantially narrower than that of the luminance component, the luminance component is used to generate a control signal which is proportional to the lack of registration between low and high frequency portions of the luminance component spectrum, and the control signal thus obtained selectively increases and decreases a delay applied to the relatively narrow-bandwidth chrominance component to substantially align its excursions with the excursions of the relatively wide bandwidth luminance component.

    摘要: An information processing apparatus of the present invention includes a touch panel for displaying predetermined information and accepting a touch operation input; and a control section for controlling operation of the information processing apparatus itself having the touch panel installed therein. The control section includes a processing occurrence detection means for detecting occurrence of a predetermined processing executed by the control section; and a panel control means for nullifying a touch operation input against the touch panel when the occurrence of the predetermined processing is detected by the processing occurrence detection means. The panel control means cancels nullification of the touch operation input against the touch panel after an elapse of a preset time from the occurrence of the predetermined processing, and sets, in association with the occurred predetermined processing, a touch operation input acceptable range allowing the touch panel to accept the touch operation input with respect to the predetermined processing.
