An intra-field interpolation method and apparatus for generating a target
pixel value. The method includes the following steps of: receiving a
plurality of pixel values of an image field; generating a first pixel
difference set from the received pixel values using a first pixel
difference algorithm; generating a second pixel difference set from the
received pixel values using a second pixel difference algorithm; and
blending the received pixel values according to the first pixel
difference set and the second pixel difference set, to generate the
target pixel value.
