An image processing apparatus or a facsimile apparatus or the like is constructed by an input unit for inputting image data, a data conversion unit for converting density characteristics of image data inputted by the input unit, and an output unit such as ink jet printer, laser beam printer, or the like for outputting the image data at a predetermined resolution. The data conversion unit converts density characteristics so as to almost equalize densities even when a resolution of the image data that is outputted by the output unit differs. The data conversion unit converts the density characteristics of the input image data on the basis of a luminance/density conversion table formed every resolution of the image data that is outputted by the output unit. The resolution of the output image data is higher than the resolution of the input image data.
