Abstract
An apparatus and a method for motion adaptive de-interlacing with chroma up-sampling error remover are provided. Wherein, a motion detector determines moving pixels and static pixels in a target scan line. A first CUE remover and a second CUE remover remove the CUE of the target scan line in the previous field and the CUE of the adjacent scan lines in the current field, respectively. A de-interlace unit de-interlaces the adjacent scan lines to obtain a de-interlaced second scan line. A selector selects output data of the first CUE remover or the de-interlace unit as data of the target scan line according to a result of motion detection of the motion detector. A merging unit merges the adjacent scan line output by the second CUE remover and the target scan line output by the selector to output two scan lines of an output field.
