摘要： A motion detector for a chrominance signal which is used with a TV receiver equipped with a video signal motion detector. This motion detector for a chrominance signal has a delay element for delaying the chrominance signal of a video signal by 1 frame period, a subtractor for subtracting the output signal of the delay element from the input signal thereof, an absolute value conversion circuit to which the output signal from the subtractor is inputted, and a smoother circuit to which the output signal from the absolute value conversion circuit is supplied. If the chrominance signals of video signals on two consecutive frames are the same, the output signal of the subtractor becomes zero. If the chrominance signals of video signals on two consecutive frames are different, the output signal of the substractor takes a positive or negative value. The negative value signal is converted into a positive value signal by the absolute value conversion circuit. A signal is outputted from the smoother circuit only when the chrominance signals of video signals on two consecutive frames are different. This outputted signal is a chrominance signal motion detection signal. The luminance signal contained in a video signal is removed from the video signal using a comb-type filter.

摘要： A video signal processing circuit of motion adaptive type includes a circuit for identifying motion of a picture in a video signal on the basis of a difference signal between at least a line signal appearing in an M-th field and a corresponding line signal appearing in an (M-1)th field so that, when a scanning line produced on the basis of the video signal is interpolated between scanning lines of the video signal to improve the picture quality, a signal for interpolating said scanning line is produced in a different manner depending on whether a portion of the video signal to the displayed is a still picture or a moving picture. The motion identifying circuit comprises a horizontal filter spreading the difference signal in the horizontal direction, a circuit delaying the output signal of the horizontal filter by one field after attenuation, a line memory delaying the output signal of the attenuating and delaying circuit by one line, and an output circuit generating a signal identifying the motion of the picture on the basis of the output signals of the horizontal filter, attenuating and delaying circuit and line memory.

摘要： A multiplex transmission method using especially a vestigial-sideband amplitude-modulated carrier modulated by a video signal. The method includes modulating a carrier having a quadrature phase with respect to an amplitude-modulated carrier by a multiplex-transmitted signal such as a digital-coded signal with a lower level as compared with the amplitude-modulated carrier, suppressing signal components of a signal obtained by modulating the carrier by a multiplex-transmitted signal, which is located near the carrier frequency, combining the result with the amplitude-modulated carrier, and thereafter transmitting the combined signal.

摘要： Disclosed is a two-dimensionally arrayed solid-state imaging device for a television camera having a photodiode array arranged at a photo-sensing section and a readout horizontal register constructed by a charge transfer device (CTD) such as a BCD, CCD or BBD. An inverter circuit is provided for each of the vertical signal lines. An input of the inverter circuit is connected to a vertical signal line drain of at least one transfer transistor arranged between the vertical signal line and the CTD, and an output of the inverter circuit is connected to a gate of the transfer transistor. Transfer efficiency is improved by the insertion of the inverter circuit and fixed pattern noise is substantially reduced by supplying bias currents.

摘要： A method and apparatus for increasing the sensitivity of a charge priming type solid state camera having means for sweeping out undesired excess charges generated by a vertical smear from vertical signal lines. When the scene illumination is higher than an appropriate value, the sweep out of the undesired excess charges is executed within each horizontal blanking period in order to reduce the vertical smear. When the scene illumination becomes lower than the appropriate value, the sweep out thereof is stopped in order to increase the sensitivity. Alternatively, when the scene illumination is lower than the appropriate value but the quantity of the vertical smear is larger than a fixed value, the sweep out thereof is executed within each horizontal blanking period in order to suppress vertical smear which is at an unacceptably high level even though the illumination level is relatively low.
