Abstract
In one or more embodiments, an image processing apparatus obtains a shade image representing shade components included in a multi-valued image obtained by capturing an image of a document. The shade components depend on an image capture environment. The apparatus binarizes a pixel value of a target pixel in the multi-valued image based on a pixel value of a corresponding pixel in the shade image at coordinates identical to those of the target pixel to generate a pixel value representing white or black. One or more image processing methods and storage mediums are also provided herein.
