ABSTRACT:
An odd pixel and an even pixel of a row of an image are selected in accordance with digital differential accumulator processing. An odd-pixel weight factor and an even-pixel weight factor are selected in accordance with the digital differential accumulator processing. A weighted odd-pixel image signal is generated by multiplying an image signal corresponding to the odd pixel by the odd-pixel weight factor and a weighted even-pixel image signal is generated by multiplying an image signal corresponding to the even pixel by the even-pixel weight factor. A horizontally scaled image signal is generated by adding the weighted odd-pixel signal and the weighted even-pixel image signal.
