Abstract:
A deinterlacing apparatus, comprising:a motion determining unit for mapping field data in a field region to be interpolated and perimeter field data around the field region and detecting a brightness difference (BD) and a brightness profile pattern difference (BPPD); a temporal interpolator for yielding a field average value about a field picture to be interpolated by averaging a pixel value of the former field and a pixel value of the after field; a spatial interpolator for detecting an edge direction comprised in the perimeter pixel values with inputs of the pixel value of the former field and after field about the field picture to be interpolated, detecting a direction indicating a minimum region matching error in accordance with the detected edge direction, and yielding an intra-field interpolation value in accordance with the detected direction; and a switch unit for mixing the yielded intra-field interpolation value and the yielded field average value in accordance with the BD and BPPD, and outputting the mixed value.
