Abstract:
1. An apparatus for motion adaptive de-interlacing with a chroma up-sampling error (CUE) remover, comprising: a motion detector for receiving data of a current field, a previous field and a next field, and determining whether a plurality of pixels between a first scan line and a third scan line in the current field are moving pixels or static pixels; a first CUE remover for receiving data of the current field and the previous field, and removing the CUE of a second scan line in the previous field, wherein the second scan line is between the first scan line and the third scan line; a second CUE remover for receiving data of the previous field, the current field and the next field, and removing the CUE of the first scan line and the third scan line in the current field; a de-interlace unit, coupled to the second CUE remover, for receiving data of the processed first scan line and third scan line, and using the first scan line and the third scan line to interpolate a de-interlaced second scan line; a selector, coupled to the motion detector, the first CUE remover and the de-interlace unit, for selecting output data of the first CUE remover or the de-interlace unit as data of the second scan line according to a result of motion detection of the motion detector; and a merging unit, coupled to the second CUE remover and the selector, for merging the first scan line output by the second CUE remover and the second scan line output by the selector so as to output two scan lines of an output field.
