Abstract
An image processing method of binarizing a plurality of multi-level tone value images including at least a first multi-level tone value image and a second multi-level tone value image, the image processing method having the processes of: converting the first multi-level tone value image into a first bitmap image consisting of binary values; replacing each binary value of the first bitmap image representing an on condition by a maximum value in a tone value range of the second multi-level tone value image and replacing each binary value of the first bitmap image representing an off condition by a minimum value in the tone value range of the second multi-level tone value image; managing the first bitmap image, whose each binary value has been replaced by the maximum value or the minimum value in the tone value range of the second multi-level tone value image, and the second multi-level tone value image as a single intermediate image; converting the intermediate image into a second bitmap image consisting of binary values, by using a threshold data matrix; and outputting the second bitmap image.
