  • Method and apparatus for de-interlacing television signal
    Patent number: 9819900
    Abstract: Method and apparatus for de-interlacing a television signal are provided. The method includes: determining whether a pixel to be interpolated is in a strictly static mode; if it is in the strictly static mode, obtaining a pixel value of a first pixel in a previous field which corresponds to the pixel to be interpolated, and setting a pixel value of the pixel to be interpolated to be equal to the pixel value of the first pixel; if it is not in the strictly static mode, determining gradient bands along a plurality of directions by taking the pixel to be interpolated as a center, determining a direction of the pixel to be interpolated based on the gradient bands, and setting the pixel value of the pixel to be interpolated by interpolation based on the direction. Accuracy of the pixel value of the pixel to be interpolated may be improved.
