    摘要: The present invention relates to an interpolation technology, in particular to a deinterlacing apparatus and a method thereof which are capable of improving the definition of a picture. The method includes detecting an edge direction comprised in perimeter pixel values with inputs of a pixel value of field data in a field region to be interpolated and intra-field perimeter pixel values, detecting a direction indicating a minimum region matching error in accordance with the detected direction, yielding an intra-field interpolation value in accordance with the detected edge direction and performing an interpolation. This reduces the manufacture cost of a circuit by simplifying the circuit.

    摘要: Disclosed is a video restoring apparatus and method thereof enabling to improve a video mode by interpolating field data. The present invention includes the steps of: identifying whether a scene on an image sequence is changed by receiving field data; detecting whether a 3:2 pull-down mode exists in the image sequence; generating a first interpolated frame by interleaving a field to be interpolated and adjacent fields each other when there is the 3:2 pull-down mode; generating a second interpolated frame by de-interlacing the field to be interpolated and the adjacent fields each other when there is not the 3:2 pull-down mode, and selectively outputting one of the first and second interpolated frames.
