Patent ID: 7242435

Claim:
A method for motion pixel detection with adaptive thresholds, included in a method for reconstructing missing pixels in an interlaced video field, said reconstructing method comprising steps of: a) inputting said interlaced video field and at least two reference fields; b) evaluating an amount of motion among said reference fields; c) adjusting at least one threshold dynamically according to said amount of motion among said reference fields; d) scanning each of said missing pixels in a raster order; e) calculating a first difference among pixels neighboring each of said missing pixels; f) comparing said first difference with said threshold; g) reconstructing each of said missing pixels by using an inter-field interpolation process if said first difference is smaller than said threshold; h) reconstructing each of said missing pixels by using an intra-field interpolation process if said first difference is larger than or equal to said threshold; i) outputting a reconstructed said missing pixels to said interlaced video field; and j) evaluating whether the scanning and reconstructing processes reaching the end of said interlaced video field.
