ABSTRACT:
Apparatus for producing television picture signals from motion picture film by scanning the film horizontally at a scanning station while transporting the film continuously past the scanning station is provided with means for accommodating different film sizes, transport speeds and film format by changing the frequency of the horizontal scan while performing a predetermined number of horizontal line scans in respect of each frame of the film; the line scan signals are stored in a memory, and the memory read to produce a plurality of television picture fields at a different frequency from that at which scanning takes place. The frequency at which the television picture fields are generated is higher than that at which the line scan is effected so that the two are made temporally compatible by repeating certain television fields in order to "fill-in" for spare time.
