摘要： When a specific signal (such as copy guard signal) is added between horizontal synchronizing signals in a composite synchronizing signal, and the addition period of the specific signal is defined in a specific period on the basis of the vertical synchronizing signal, the composite synchronizing signal is masked to remove the specific signal, thereby obtaining a masked composite synchronizing signal. Afterwards, from the masked composite synchronizing signal, the horizontal synchronizing signal and vertical synchronizing signal are obtained. In the case of composite synchronizing signal containing noise, without masking, the horizontal synchronizing signal and vertical synchronizing signal are directly obtained from the composite synchronizing signal. Therefore, when noise is not present, the horizontal synchronizing signal and vertical synchronizing signal may be obtained without disturbing the video image.
摘要翻译：当在复合同步信号中的水平同步信号之间添加特定信号（例如复制保护信号），并且基于垂直同步信号在特定周期内定义特定信号的相加周期时，复合同步信号被掩蔽以去除特定信号，从而获得掩蔽的复合同步信号。之后，从掩蔽的复合同步信号中获得水平同步信号和垂直同步信号。在包含噪声的复合同步信号的情况下，没有掩蔽，从复合同步信号直接获得水平同步信号和垂直同步信号。因此，当不存在噪声时，可以获得水平同步信号和垂直同步信号而不干扰视频图像。

摘要： A phase looped oscillating circuit includes a signal comparing device which can compare a plurality of different input signals with each other and emit a signal based on this comparison. The signal comparing device emits a control signal to a level converting device, a signal converting device is operatively connected to the level converting device. A signal from the converting device is received by an oscillating device and an oscillating signal is fed back to the signal comparing device via a divider. To compensate for fluctuation of an invertor in the signal converting device, the signal comparing device provides a fixed level signal stabilized at a 50% duty cycle. This stabilization also stabilizes electrical noises that may be present.

摘要： An improved flat display apparatus such as a liquid crystal display apparatus is disclosed. The apparatus is constructed so that when video signals from a VTR is reproduced to be displayed, the switching noise portion included in the video signals is changed to black level before being displayed, the section within the picture image area in which the switching noise originally appeared is masked by black level, making it possible to conceal the disorder in the picture image. In the case where television video signals are to be displayed, the picture can be enjoyed on a wide picture image area because the mask of black level is not generated.

摘要： A switching circuit selects a display control circuit in an image display period, and selects a detection control circuit in an x-coordinate detection period. A row electrode drive circuit outputs row electrode scanning pulses in the image display period to sequentially scan row electrodes. A column electrode drive circuit outputs column electrode scanning pulses in the x-coordinate detection period to sequentially scan column electrodes. A coordinate detection circuit detects coordinates at a tip end of a detection pen based on an induction voltage induced at a tip electrode of the detection pen due to the scanning pulses. Accordingly, by detecting a y-coordinate at the tip end of the electronic pen in the image display period and detecting the x-coordinate in the x-coordinate detection period, a display-integrated type tablet device can achieve an increase in area of its display screen, high productivity, cost reduction, and high coordinate detection accuracy.

摘要： The invention relates to a drive apparatus for a liquid crystal display device. The voltage, to be applied to longitudinally and latitudinally arranged liquid crystal cells of the liquid crystal display device, is altered in polarity from field to field and from frame to frame, whereby the occurrence of flicker is prevented. The field discriminating device counts the numbers of lines in first and second fields by synchronizing a vertical synchronizing signal at a leading point of a field time. Thereafter the difference in the number of lines between the first and second fields is detected, the field times being thereby discriminated. When a video signal is erroneous, the field discriminating device provides a field discriminating signal, the level of which is changed alternately from field time to field time.
