Abstract
An image processing apparatus includes a processor for acquiring an input image, calculating a fluctuation range of a gradation value of a pixel within a region corresponding to a document backing in the input image, determining a threshold, based on the fluctuation range, extracting an edge pixel corresponding to a boundary between a document and the document backing from the input image using the threshold, detecting a document region from the edge pixel, and an output device for outputting an image obtained by cutting a region corresponding to the document region from the input image.
