ABSTRACT:
A plurality of image signals corresponding to a row of an image are selected based on digital differential accumulator processing. A plurality of weighted image signals are generated by multiplying the plurality of image signals by one or more weight factors selected in accordance with the digital differential accumulator processing. A weighted sum signal is generated by summing the plurality of weighted image signals and a horizontally scaled image signal is generated corresponding to the plurality of image signals from the weighted sum signal.
