ABSTRACT:
A picture signal processing apparatus in which video source signals, that is interlaced video signals conforming to, for example, the NTSC standard television broadcasting system, obtained on conversion (so-called tele-cine conversion) from a 24-picture frame-per-second picture from a film source, such as a motion picture, are reconverted for generating signals corresponding to a pre-tele-cine-conversion picture, that is picture signals of 24 picture frames per second directly obtained from the film source. The signals corresponding to a picture prior to tele-cine conversion may be restored even from video source picture signals produced on tele-cine conversion in which the picture frame breaking point is not coincident with the field boundary.
