ABSTRACT:
An image processing apparatus for interpolating an input image and outputting an interpolated input image, includes a pipeline operation unit for selectively performing interpolation operations at a plurality of magnifications, a CPU for causing address counters to select one of the plurality of interpolation magnifications for the pipeline operation unit on the basis of an input image pixel count, an output medium pixel count, a designated output image count, and a designated output image layout, a display or printer for outputting an image interpolated by the pipeline operation unit in accordance with the designated output image layout. The input image is interpolated at a magnification determined such that a size of an output image falls within an area an output medium.
