摘要: In an apparatus and method for deriving gradient vectors use in the spatial interpolation of input digital video signal; scan lines a field signal are high pass filtered so as to provide which is supplied plurality parallel processing channels differently low form respective signals, correlation range pixel offsets determined pixel-by-pixel outputs from each signal, vector selected, corresponds maximum value therefor. The also applicable television standards converter.
