ABSTRACT:
In an image processing apparatus disclosed, an image evaluation means divides an original image data into the number of blocks as based on a reduction rate, and evaluates the image data of each block to determine evaluation values. The image determining means compares the evaluation value of each block with the threshold value preset for each block, to determine if the reduced image of each block is set to black or white. An executing means causes the image evaluation means and the image determining means to execute their processings the number of times as based on a reduction rate.
