Abstract
There is provided an image reading device in which a controller is configured to perform detecting, by executing an edge detection process, edge pixels from image data scanned by a reading device and stored in a storage, the edge pixels being pixels obtained by reading an edge of an original document. Then, it is determined whether a sequence of the detected edge pixels in a particular direction is interrupted. When interrupted, an expansion process is executed to increase the edge pixels in a particular range in a neighborhood of the detected edge pixels of the image data. Then, a particular process is performed on the image data using the edge pixels detected from the image data after the edge pixels are increased.
