1. image transfer converter comprises:

  • First buffer, second buffer and the 3rd buffer, the video field of storage order input sequentially;

    Exercise estimator, the motion vector between the 3rd of storing in first of estimating in first buffer, to store and the 3rd buffer;

    Motion compensator compensates the motion between first and the 3rd through using the motion vector of being estimated by exercise estimator, thereby produces the interpolation field;

    In store in the interpolation field that output unit, output are produced by motion compensator and second buffer second at least one;

    WithThe field selector, said selector comprises;

    the film mode determiner, confirm that the video field of order input is drop-down film mode of 3;

    2 or the drop-down film mode of 2;

    2, perhaps not drop-down film mode;

    With select signal output unit, according to the confirming to export and select signal of film mode determiner with one of second of selecting to store in the interpolation field and second buffer,Wherein,, then select dropscene that signal output unit output selects the repeat fields that signal imports with the output of control output unit in proper order as the interpolation field if the video field of order input is the drop-down film mode of 3;

    2,If the video field of input is the drop-down film mode of 2;

    2 in proper order, then select signal output unit output to select signal every at a distance from an output interpolation field with the control output unit,If order input is not drop-down film mode, then select signal element output select signal with the output of control output unit not by second of interpolation.
