Abstract
A video pixel interpolator generates interpolation pixels from incoming picture image pixels for use within a television picture scan line doubler system. The interpolator includes a temporal median filter for generating an interpolation pixel by selection of the median one of a plurality of temporal pixel samples derived from incoming video, an intra-field averager means for generating an intra-field pixel average, and a switch connected to switch an input to a line doubler of the system between outputs of the temporal median filter and the intra-field averager in response to detection of pixel motion within the picture image. Improved motion detection, and multi-channel processing are also included within the present invention.
