Abstract:
An image-reading device may include a conveyor, a reading unit, and a control device. The control device may be configured to extract feature points from an area between a first edge and a line, obtain the density of the extracted feature points, and compare the density to a threshold. The control device may be further configured to identify the first edge as a document leading edge or a document trailing edge based on the comparison result.
