PCT No. PCT/GB89/00918 Sec. 371 Date Feb. 11, 1991 Sec. 102(e) Date Feb. 11, 1991 PCT Filed Aug. 10, 1989 PCT Pub. No. WO90/01854 PCT Pub. Date Feb. 22, 1990.An intermittent motion flying spot telecine capable of operating in real time provides an adequate film pull down time to allow the use of pin-registration by including a digital scan corrector (18) and a picture store and sequential-to-interlace converter (19) and by adjusting the CRT scanning circuitry (24). Three measures are employed: (I) the film is scanned with a sequential scanning raster and subsequent sequential-to-interlace conversion is performed, so as to combine two field blanking intervals into one longer one, (II) data is written into the picture store at a faster rate than required for the output and read out at a conventional rate, and (III) a triangular line scanning waveform is employed to allow line flyback time to be removed and the instantaneous line rate increased. |
