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.
