ABSTRACT:
The present invention relates to a deinterlacing device and method for converting a video signal of an interlaced scan format into a video signal of a progressive scan format. The deinterlacing method including the steps of: measuring an edge gradient from a series of pixels provided in an upper scan line and a series of pixels provided in a lower scan line with reference to a pixel to be interpolated; determining an interpolation method on the basis of the measured edge gradient; calculating a difference value for each of pixel pair combinations, each of the pixel pair combinations having at least one pixel pair, the pixel pair having two pixels each one from each of the upper and lower scan lines with reference to the pixel to be interpolated, each of the pixel pair combinations having the pixel pairs that are adjacent to one another, the pixel pair combinations having different directions from one another; determining an edge direction on the basis of a direction of the pixel pair combination having the smallest difference value; and performing an interpolation for the pixel depending on the determined interpolation method and the determined edge direction.
