ABSTRACT:
An image processing apparatus includes an input unit for inputting image data having a plurality of pixels and representing whether each pixel is a white/black pixel, and a processing unit for performing a smoothing process for the image data to convert the input data into image data having a higher resolution than the input image data. The processing unit performs the smoothing process by performing interpolation processing for white pixels of the input image data.
