ABSTRACT:
An apparatus for processing an image containing a plurality of original lines of pixels to generate one or more intermediate lines of pixels lying intermediate the original lines includes means for storing the original lines of pixels, means for estimating line shift velocities for pixels along the intermediate lines where the velocities are derived from surrounding pixels on the original lines, means for using the estimated line shift velocities to access the addressable memory and shift pixels from the original lines, means for generating the characteristics of pixels along the intermediate lines from the characteristics of the pixels shifted by the line shift velocities, and means for displaying or storing the generated characteristics of pixels along the intermediate lines.
