Analyzing an image signal 720 to locate the scan lines at upper edge and lower edge of the image; and dividing the image data of said scan lines by two and outputting said divided image data twice in both the even field and odd field. An apparatus is also provided for driving an interlaced plasma display panel (PDP), comprising a delay device 701 for receiving an image signal 720, delaying said image signal for a plurality of fields and outputting said delayed image signal 721; an image upper and lower edge detection device 705 for receiving and analyzing said image signal, outputting an upper and lower edge position of said image signal, saving and providing an odd field upper and lower edge data 724 of said image signal; an image border processing device 703 for outputting said image signal 723 after border processing according to said delayed image signal 722, said upper and lower edge positions and said odd field upper and lower edge data 724; and an image processing and analog control loop 704 for outputting a driving signal 726 according to said image signal 723 after boundary processing and said upper and lower edge positions 725. |
