Abstract:
1. An image processing apparatus, including an image processing section for processing multilevel image data, for generating image data that allows a preview image of binary image data to be displayed by an image displaying device for displaying an image of multilevel image data, the image processing apparatus comprising: a tone conversion process section for converting tones of binary image data into a maximum tone and a minimum tone of multilevel image data processed by the image processing section; a smoothing process section for performing a smoothing process on image data resulting from the conversion by the tone conversion process section; and an interpolation process section for performing an interpolation process on the image data subjected to the smoothing process by the smoothing process section, so that smoothness of tones of the image data is maintained, the image data subjected to the interpolation process by the interpolation process section being supplied to the image display device, and the smoothing process section performing a filter process as the smoothing process and including a filter coefficient selection section for selecting a filter coefficient in accordance with resolution of the binary image data.
