Abstract
A de-interlacing method includes the following steps. A de-interlacing pixel datum of a target pixel is obtained according to a current field and multiple correlated fields. A caption region of the current field is defined according to the fields, and a region motion vector and a region confidence are correspondingly obtained. When the target pixel belongs to the caption region, a compensation pixel datum of the target pixel is obtained by motion compensation according to at least a part of the fields and the region motion vector, and the target pixel is judged as a foreground pixel or a background pixel to output a compensation select signal according to the region motion vector and the region confidence. The de-interlacing pixel datum or the compensation pixel datum is outputted as a correlated pixel datum of the target pixel according to the compensation select signal.
