Abstract
A method of adaptive deinterlacing of video data includes generating a selected pixel value at a given pixel position of a current interlaced field by either weaving a pixel value from another interlaced field, when no motion is detected at the pixel position, or by interpolating between other selected pixel values of the current field, when motion is detected at the pixel position. When the pixel value is generated by weaving, a test for feathering is performed. If feathering is detected, a further check is performed for motion at the pixel position over a selected number of preceding fields. In the absence of motion over the preceding fields, the weaved pixel value is utilized as the selected pixel value. If motion is detected over the preceding fields, interpolation is performed between selected pixel values of the current field to generate the selected pixel value.
