Abstract
A process is provided for creating a high resolution copy of a target video frame selected from a sequence of video frames, wherein each video frame comprises two interlaced fields. The process comprises the steps of: selecting a single field of the target video frame for resolution enhancement; defining a reference target frame having pixel values assigned from the selected single field; defining an enlarged target frame having pixel locations corresponding to the high resolution copy; assigning pixel values from the selected single field to pixel locations in the enlarged target frame which correspond to pixel locations in the selected single field; assigning estimated pixel values to unassigned pixel locations in the reference target frame; selecting a field from one of the video frames in the sequence of video frames which was not chosen as the selected single field as a first object field; estimating motion vectors extending from the reference target frame to pixels in the first object field; identifying accurate motion vectors; assigning the value of a respective pixel for each motion vector identified as accurate to an enlarged target frame pixel location corresponding to an origination point of the motion vector unless the enlarged target frame pixel location was previously assigned a pixel value; and printing the enlarged target frame. Further provided is printing apparatus for creating a high resolution copy of lower resolution video information.
