Zusammenfassung: | A method for TV recording of pictures from a moving picture film which is continuously moved relative to a recording screen, the pictures of the film each being periodically scanned linewise, whereby the moving picture frequency with respect to the scanning frequency is in a predetermined relation with respect to each other for the purpose of achieving a predetermined recording picture frequency, for example of 50 pictures per second. With different moving picture frequencies (fL) the following relationship with respect to the scanning frequency (fA) is maintained: fL+fA=+F in which F means the desired recording picture frequency, whereby at least with one of the moving picture frequencies which is used, fractions of a picture are scanned per scanning period, which fractions differ from 1 picture, particularly exceeding 1. |
