摘要： A high quality non-interlaced television signal is generated without using a large size circuit. Interlaced television signals are obtained from four image pickup devices. A luminance or green signal in the interlaced television signals consists of two interlaced channels. These two channel luminance or green signals are simply combined to produce the non-interlaced signal without modifying the driving frequency of the image pickup devices.

摘要： A television signal digitizing method reduces the quantity of information without deterioration of image quality when digitizing progressive-scanned signals. The method uses a step of dividing a progressive-scanned information into two complementary interlaces, that is, an interlace 1 and an interlace 2; a step of converting luminance information in the interlace 1 to digital information whose sampling frequency is X; a step of converting chrominance information in the interlace 1 to digital information whose sampling frequency is Y; and a step of generating supplementary information.

摘要： An anti-ringing device for a television signal transmission system in which the frequency band of a luminance component of a video signal from an image device is limited to prevent visible ringing at the receiver. The device includes a signal delay circuit 2 for delaying the video signal obtained by the image device, a low-pass filter 3 capable of changing the frequency band limitation characteristics thereof, a discriminator 4 for providing an output when the luminance component of the video signal contains a source of ringing, and a switch 5 for normally connecting the output of the delay circuit to a signal processor 6. The switch is responsive to the output of the discriminator for connecting the low-pass filter to the signal processor instead of the delay circuit, whose delay time corresponds to the signal processing time required in the discriminator.
