摘要： A video signal of an interlaced scanning system having 525 scanning lines and a vertical scanning frequency of 60 Hz is converted to a video signal having 1050 scanning lines and a vertical scanning frequency of 120 Hz, for displaying an image by bidirectional scanning. A vertical synchronizing signal is subjected to offset processing by a ¼ horizontal scanning period when an odd field is started, thereby keeping interlaced relation between odd and even fields. The vertical synchronizing signal is subjected to offset processing by a ½ horizontal scanning period every frame, so that the scanning direction for each scanning line is reversed every frame.

摘要： A vehicular air conditioning refrigerant compressor is disclosed. The variable displacement compressor includes a suction chamber, a discharge chamber, a crank chamber, a drive shaft having rotated by a vehicle engine, a swash plate rotatable with the drive shaft and located within the crank chamber. The swash plate and the drive shaft have a tilt angle between them. The tilt angle is controlled by a control valve mechanism which regulates the introduction of a gas from the discharge chamber to the crank chamber. The compressor further includes a center sleeve slidably mounted on the drive shaft. The position of the center sleeve is responsive to the tilt angle. The compressor also includes a relief passage for relieving gas from the crank chamber to the suction chamber, and includes an axial hole in the drive shaft having an opening at one end of the drive shaft and an end within the drive shaft, a vertical hole in the drive shaft having two openings on the surface of the drive shaft and perpendicular to said axial hole. The vertical hole intersects the axial hole near the end of the axial hole. The relief passage further includes a passage in fluid connection with the suction chamber and the opening of the axial hole. The aperture of the two openings is regulated by the position of the center sleeve.

摘要： A component of color difference signal is detected from a video component signal, and its color saturation information is compared with a predetermined threshold level, then in response to the comparison result, information is generated in order to control phase modulation such as, when the information is smaller than the threshold level, phases of color burst signals are modulated during a specified period, and when the information is larger than the threshold level, the phase stays as standard. The generated information is added to the color video signal. These steps can avoid unpleasant striped color noises appeared on a conventional color TV receiver, the unpleasant striped color noises has been caused by a modified color burst signal without the above steps.

摘要： A noise reduction apparatus for use in a television receiver or VCR using the NTSC format, in which a video signal or a demodulated color difference signal is processed by an operational circuit which supplies a noise-reduced output signal to a first one of two series-connected one-frame delay elements and which compares the input video signal with an output signal from the first 1-frame delay element, to execute noise reduction. A degree of noise reduction executed by the operational circuit is controlled in accordance with the degree of correlation between the output signal from the second 1-frame delay element and the input video signal, such that the degree of noise reduction is made small or zero when the correlation is below a predetermined level, indicating the presence of motion components in the video signal. Due to the 2-frame delay used in judging that degree of correlation, the judgement will not be adversely affected by interference components of the video signal which result from interaction between the chroma and high-frequency luminance components of the video signal, when there are no motion components in that signal.
摘要翻译：一种用于电视接收机或使用NTSC格式的VCR的降噪装置，其中视频信号或解调的色差信号由将噪声降低的输出信号提供给两个串联的第一个的操作电路来处理，连接的一帧延迟元件，并且将输入视频信号与来自第一1帧延迟元件的输出信号进行比较，以执行降噪。根据来自第二1帧延迟元件的输出信号和输入视频信号之间的相关程度来控制由操作电路执行的噪声降低程度，使得降低噪声的程度小或为零，相关性低于预定电平，指示视频信号中存在运动分量。由于用于判断相关程度的2帧延迟，所以判断不会受视频信号的色度和高频亮度分量之间的相互作用产生的视频信号的干扰分量的不利影响，当有该信号中没有运动分量。
