ABSTRACT:
An apparatus, circuit arrangement, program product and method of scaling an image horizontally partition a source image into a plurality of partitions, with each partition having a width that is no greater than the width of a line buffer used to scale the image. By partitioning an image into a plurality of partitions, the overall width of the scaled image is not constrained by the width of the line buffer. As a result, in many instances line buffers that are significantly smaller than conventional full-width line buffers may be used to generate scaled images that are substantially wider than may be generated by conventional buffers. Moreover, when implemented in hardware, the line buffers typically occupy significantly less real estate on an integrated circuit, thus reducing both cost and power consumption.
