ABSTRACT:
There is disclosed an image processing device for performing a conversion processing of image data, comprises an input unit for inputting image data, an enlargement/reduction magnification setting unit for setting an enlargement/reduction magnification of the image data inputted by the input unit, a data converting unit having a plurality of image data conversion tables and using one selected conversion table to convert the inputted image data to output data, and a table selecting unit for selecting the conversion table in accordance with the enlargement/reduction magnification set by the enlargement/reduction magnification setting unit. In the enlargement/output of the image by the image processing, the edge portion of output image can be prevented from being blurred by the enlargement processing. Moreover, in the reduction/output of the image, even when the reduction processing is performed, the reproducibility of intermediate gradation density fine lines in the input image can be enhanced.
