1. , a kind of method comprises:

  • Obtain the inputting video data field to small part, this part comprises the field pixel of the continuous four lines of part, and continuously the field pixel of four lines comprises first, second, third and fourth line field pixel;

    Select a direction, on this direction to small part based on the continuous four lines of field pixel and fifth line pixel between the deviation measurement of pixel value carry out the edge direction interpolation of inputting video data, described fifth line pixel second and the third line field pixel between, the fifth line pixel comprise use the edge direction interpolation and the pixel value of previous interpolation and by second and the pixel value of the third line field pixel between the average and pixel value of interpolation of row;

    WithAlong selected directional interpolation to determine output pixel value.
