Abstract:
1. An image processing apparatus, comprising: an image reading mechanism configured to read an original image to produce an input image; a display displaying at least one image; a memory storing a plurality of stepped values representing an image density threshold parameter; an image processing mechanism configured to perform an image processing operation that includes generating a first corrected image by applying a first correction to the input image using a first stepped value of the plurality of stepped values, and generating a second corrected image by applying a second correction to the input image using a second stepped value of the plurality of stepped values; an image creating mechanism configured to create first and second subtractive images based on comparisons of the first corrected image and the second corrected image; and a controller configured to control the display to display the input image, the first corrected image, the second corrected image, the first subtractive image, and the second subtractive image in a screen image.
