  • Image processing method and apparatus, and computer readable data storing medium storing a program for image processing
    Patent number: 7471414
    Abstract: An image processing apparatus including an image reading mechanism, a display, a memory, an image processing mechanism, an image creating mechanism, and a controller. The image processing mechanism performs first and second corrections using the plurality of stepped values. The image creating mechanism creates first and second subtractive images based on a first corrected image corrected by the first correction and a second corrected image corrected by the second correction. The controller controls the display to display the input image, the first corrected image, the final corrected image, the first subtractive image, and the second subtractive image in a screen image. A method of image processing and a computer readable data storing medium storing a program for image processing are also described.
