Abstract
An image de-interlacing method for estimating an interpolation luminance of an interpolated pixel, including: selecting a plurality of first and second candidate pixels respectively on upper and lower lines adjacent to the interpolated pixel, calculating a plurality of weighted directional differences respectively associated with one of the first candidate pixels and one of the second candidate pixels with weighting values determined by comparing similarity of luminance decreasing/increasing patterns near the associated first and second candidate pixels on the upper and lower lines, selecting a first selected pixel and a second selected pixel respectively from the first and second candidate pixels associated with the smallest weighted directional difference, and obtaining the interpolation luminance according to the first and second selected pixels.
