Abstract
A line structure correction circuit for reducing the visibility of the raster line structure of a television picture which is to be photographed. The picture information associated with each raster line in the television picture signal is repeated n-times, n being an integer at least equal to two. The raster-line information is applied to a television display device operated at the same line period as the picture signal but with an n-times longer picture or frame period, respectively, depending on whether the television picture is interlaced. A further improvement in the quality of the recording is obtained by forming the information in each raster line of the television picture from different combinations of the information associated with consecutive raster lines in the picture signal.
