摘要： Luminance and chrominance signals, which are interleaved with respective synchronization signals, are recorded through the use of two video transducer heads alternately in skewed separate tracks of a recording tape. Upon reproduction, the timing signals are separated from the luminance and chrominance signals and compared in phase between them to detect the phase difference between the luminance and chrominance signals. A variable delay line is provided to introduce a variable delay interval as a function of the detected phase difference to the one of the signals which is advanced in phase relative to the other. The time axis deviation of the video signal from a standard phase is also detected by a comparison between the time base, or horizontal sync pulse, and a reference time base to introduce a delay time to both the luminance and chrominance signals.

摘要： In a system for cancelling time axis variations introduced into a frequency converted chrominance signal converted into a lower frequency range in the recording and reproduction of a color television signal with a small-size video tape recorder, in which system the cancellation of the time axis variations is effected by using a continuous reference signal obtained through an APC heterodyne system, the center frequency of oscillation of an APC oscillator is made n/m times the subcarrier frequency f.sub.s of the lower frequency converted chrominance signal (m and n being integers and n>m), and the reproduced frequency converted chrominance signal is heterodyned with a signal obtained by heterodyning a continuous signal obtained by dividing the frequency of the output signal of the oscillator by n/m in the presence of a steady reference signal at the same frequency as the standard color sub-carrier frequency to thereby obtain the cancellation of the time axis variations.

摘要： An apparatus for processing a progressive scanning video signal comprising a progressive to interlaced signal converter is provided. An input progressive scanning video signal is switched over alternately every one horizontal scanning line of progressive scanning so as to be divided into a main original signal and a sub-original signal. A time interval of the main original signal is expanded so as to convert the main original signal into a main signal having a period of horizontal scanning of interlaced scanning, whereas a time interval of the sub-original signal is expanded so as to convert the sub-original signal into a sub-signal having the period of the horizontal scanning of the interlaced scanning. Further, a synchronizing process is performed on the time-expanded main signal and the time-expanded sub-signal so as to output an interlaced scanning signal including the main signal and the sub-signal in synchronous with each other, and so that the main signal and the sub-signal start respectively from a pair of two horizontal lines which is continuously inputted after the first horizontal scanning line of the input progressive scanning video signal.

摘要： The present invention provides a method of driving an active matrix display device in which one frame comprises a plurality of sub-frames each comprising a write time and a hold time and gray scale driving is brought about by the cumulative effect of the hold times. Gray scale display driving is carried out by randomly scanning scan lines other than one predetermined scan line in a predetermined sequence in the hold time of each sub-frame corresponding to the one predetermined scan line so that any one sub-frame is not written to any one scan line more than once and one frame is such that in each of the scan lines, the writings and the hold time of each of the sub-frames is ensured to bring about gray scale display. Through this means, the frame period is shortened.
