Abstract
A method for interpolating a pixel during the deinterlacing of a video signal, the video signal including at least two fields of interlaced scan lines, each scan line including a series of pixels having respective intensity values, includes generating a motion value representative of the motion between successive frames about the pixel, detecting an edge direction about the pixel, performing an edge adaptive interpolation at the pixel, using the detected edge direction, and performing a motion adaptive interpolation at the pixel, using the generated motion value. Apparatus for interpolating a pixel during the deinterlacing of a video signal, the video signal including at least two fields of interlaced scan lines, each scan line including a series of pixels having respective intensity values, includes a motion value generator configured to generate a motion value representative of the motion between successive frames about the pixel, an edge direction detector configured to detect an edge direction about the pixel, an edge adaptive interpolator configured to perform an edge adaptive interpolation at the pixel, using the detected edge direction, and a motion adaptive interpolator configured to perform a motion adaptive interpolation at the pixel, using the generated motion value.
