Изобретение относитс к приборостроению и может быть использовано в технике цветной видеозаписи и воспроизведени .The invention relates to instrument making and can be used in color video recording and reproduction techniques.
Известно устройство автоматической коррекции частотных характеристик видеомагнитофона, содержащее источник пилот-сигнала, блок записи в интервал кадрового гас щего импульса, блок видеоголовок , электронный переключатель два усилител с потенциально-управл емой амплитудно-частотной характеристикой и демодул тор ll .A device for automatically correcting the frequency characteristics of a video recorder is known, which contains a source of a pilot signal, a recording unit for a frame damping pulse, a video head unit, an electronic switch two amplifiers with a potential controlled amplitude-frequency characteristic, and a demodulator ll.
Наиболее близким к изобретению по технической сущности вл етс устройство автоматической коррекции частотной характеристики видеомагнитофона, содержащее усилитель с потенциальноуправл емой амплитудно-частотной характеристикой , подключенньо к демодул тору , и запоминающую емкость, включенную между земл ной шиной и точкой соединени выхода ключа запоминани со входом блока сравнени 2jClosest to the invention, the device is an automatic correction of the frequency response of a video recorder, containing an amplifier with a potentially controlled amplitude-frequency characteristic connected to the demodulator, and a storage capacitor connected between the ground bus and the connection point of the memory key output to the input of the comparison unit 2j
Недостатком известных устройств вл етс низкое качество воспроизводимого цветного изображени , св занное с низким быстродействием автоматической коррекции.A disadvantage of the known devices is the poor quality of the reproduced color image due to the low speed of the automatic correction.
Целью изобретени . вл етс повышение качества воспроизводимого цветного изображени .The purpose of the invention. is an improvement in the quality of the reproduced color image.
Поставленна цель достигаетс введением в устройство цветного синкронизатора , подгслючениог о входом к т модул тору , а В1зхопом к ключу .апоминани The goal is achieved by introducing a color syncronizer into the device, connecting the input to the modulator, and entering the key to the memory.
