Abstract
De-interlacing of interlaced image fields to obtain non-interlaced image frames includes removing the blank lines of each image field and removing one-half of the pixels of the remaining lines of each image field, thereby to obtain image frames having one-half the number of lines (i.e about one-half the vertical resolution) and one-half the number of pixels in each horizontal line (i.e. about one-half the horizontal resolution). Removing the blank lines may include interpolating pixel values for lines in the positions of the blank lines from the pixel values of adjacent lines, retaining the interpolated lines, and removing the adjacent lines, thereby to substantially reduce vertical jitter that would be caused by the one-half line positional difference between adjacent image fields. The invention has the advantage of greatly simplifying the implementation of such de-interlacing arrangement.
