Abstract:
1. A de-interlacing apparatus, comprising: a de-interlacer for obtaining a de-interlacing pixel datum of a target pixel according to a current field and a plurality of correlated fields; a moving caption compensator for defining a caption region of the current field according to the fields and correspondingly obtaining a region motion vector and a region confidence, wherein when the target pixel belongs to the caption region, the moving caption compensator obtains a compensation pixel datum of the target pixel by motion compensation according to at least a part of the fields and the region motion vector, and judging the target pixel as a foreground pixel or a background pixel to output a compensation select signal according to the region motion vector and the region confidence; and a multiplexer controlled by the compensation select signal to output the de-interlacing pixel datum or the compensation pixel datum as a correlated pixel datum of the target pixel.
