PURPOSE:To obtain a good picture with a few judder through a miniaturized equipment by analyzing a motion between continuous fields of an input TV signal, and obtaining a still picture by lining up the field, and converting it into the output TV signal of another type. CONSTITUTION:The inpput TV signal of 625 lines 50 fields/sec is sent to a four-field time base corrector 11, and one of the output of it motion-analyzes 2 the input TV signal, and other outputs are sent to field memories 12-16 through a frame delay unit 17. Then, according to samples, obtained from the memories 12-16, and motion picture data, obtained from an analyzer 2, the signal of 585 lines 60 fields/sec is outputted from an interpolator 1. This signal outputs the video signal of 525 lines 60 fields/sec through a two-field time base corrector 18. Similarly, the video signal of 525 lines 60 fields/sec can be converted into the TV signal of 625 lines 50 fields/sec two-field time base correcting 21, motion-analyzing 2, interpolating 1, and four-field time base correcting 22 it. |
