ABSTRACT:
A de-interlacing device having a pattern recognizing unit and a method therefor for receiving an interlaced image and outputting a non-interlaced image. The de-interlacing device includes a first de-interlacing unit, a second de-interlacing unit and a pattern recognizing unit. The pattern recognizing unit receives the interlaced image, recognizes whether or not the interlaced image has an obviously horizontal pattern, outputting the interlaced image to the first de-interlacing unit if yes, and outputting the interlaced image to the second de-interlacing unit if not. The first de-interlacing unit and the second de-interlacing unit use different de-interlacing methods. The first or second de-interlacing unit receives the interlaced image outputted from the pattern recognizing unit and outputs the non-interlaced image accordingly.
