Abstract
Disclosed are an image processing method and apparatus for converting the processed block of bi-level image data to a block having a size conforming to the magnification of zoom processing and deciding, based upon the pixel pattern of the bi-level image data, output values within the converted processed block. The output values are decided in such a manner that pixel density of the bi-level image data is preserved within the converted processed block.
