ABSTRACT:
A video processing apparatus and method are disclosed. The video processing apparatus includes a first de-interlacer to de-interlace standard definition (SD)-level interlaced video signal into an SD-level progressive video signal by using spatial-temporal interpolation and output the SD-level progressive video signal, a scaler to convert the SD-level progressive video signal into a high definition (HD)-level interlaced video signal and output the HD-level interlaced video signal, and a second de-interlacer to de-interlace the HD-level interlaced video signal into a HD-level progressive video signal by using spatial interpolation and output the HD-level progressive video signal. Accordingly, an artifact ca be prevented from appearing at a vertical edge of an image.
