Patent ID: 7142223

Claim:
A method for interpolating a pixel value for a blank pixel location in a field from an interlaced video stream, the method comprising: selecting a boundary pixel grouping comprising common-field pixel pair comprising a common-field pixel and a cross-field pixel pair comprising a cross-field pixel, wherein both the commonfield pixel pair and the cross-field pixel pair surround the blank pixel location; generating a weighted average from the boundary pixel grouping by: multiplying a luminance of a bottom pixel in the common-field pixel pair by a weighting coefficient to generate a first interpolated portion; multiplying a first cross-field luminance value by a complement of the weighting coefficient to generate a second interpolated portion, wherein the first cross-field luminance value is based on a luminance value of the cross-field pixel; and adding the first interpolated portion to the second interpolated portion to generate the weighted average; and assigning the weighted average to the blank pixel location.
