ABSTRACT:
A process and apparatus for generating a deinterlaced digital output image from a plurality of sequential interlaced image fields processes selected ones (a pair of immediately successive fields of the same polarity) of the plurality of sequential interlaced image fields, so as to produce a global motion vector estimate of global translational motion between the selected image fields. An accuracy map representative of accuracy of motion compensation is then generated in accordance with the global motion vector estimate. An adaptive deinterlacer selectively deinterlaces one of the image fields in accordance with the accuracy map. The selectively deinterlaced image field is subjected to postprocessing in order to remove judder artifacts that may be present in the deinterlaced image field as a result of a misclassification of the global motion vector estimate as being accurate in one or more image regions of the deinterlaced image field.
