专利汇可以提供Noise removing circuit专利检索,专利查询,专利分析的服务。并且PURPOSE: To provide the noise reduction circuit of a video signal recording and reproducing device which is suppressed in the deterioration of the vertical resolution of a reproducing screen and an increase in rainfall noise and to simplify the circuitry thereof.
CONSTITUTION: The noise reduction circuit of the reproducing system of a VTR is constituted of the combination of the noise reduction circuits (8 to 12) of a recursive type and the noise reduction circuits (12 to 16) of a nonrecursive type. The noise reduction circuits (8 to 12) of the recursive type function as vertical deemphasis circuits to apply vertical deemphasis on reproduced brightness signals. On the other hand, the noise reduction circuits (12 to 16) of the nonrecursive type cancel the noise components having no line correlation characteristics from the reproduced brightness signals subjected to the vertical deemphasis. The vertical deemphasis and the noise reduction are separately executed in such a manner and, therefore, the image quality is improved.
