Abstract:
An apparatus for enhancing the resolution of video data adapted to enhance the resolution of an incoming video data sequence composed of a plurality of video data each corresponding to a pixel, to generate a high definition video data sequence, said apparatus comprising:vertical resolution enhancement processing means including a plurality of memories for sequentially storing one horizontal scanning line portion of each video data in said incoming video data sequence, reading means for repetitively reading a first video data group having said one horizontal scanning line portion of video data and a second video data group having video data one horizontal scan period before said first video data group from said memories N times (where N is a natural number) within said one horizontal scan period, and mixing means for mixing said first video data group and said second video data group with a mixing ratio, said mixing ratio being switched each time said video data groups are read from said memories, to generate a video data sequence having the resolution enhanced in the vertical direction by a factor of N; and horizontal resolution enhancement processing means for interpolating said video data sequence to generate a video data sequence having the resolution enhanced in the horizontal direction, and for outputting said video data sequence as said high definition video data sequence.
