Patent attributes
A three-dimensional de-interlacing method and apparatus for converting an interlaced scan format image into a progressive scan format image by performing low pass filtering on respective predetermined pixels of a current frame and a previous frame and determining pixel motion index values by comparing a threshold value to a difference value between the respective filtered pixels in a current field in one of the current and previous frames and corresponding respective filtered pixels in preceding and succeeding fields to the current field and in the current and previous frames. A motion mode of a pixel is determined based upon the determined motion index values of temporally and spatially adjacent pixels to the pixel. A spatial interpolation or temporal interpolation on the subjected pixel is selected depending on the determined motion mode.
