Abstract
An image processing apparatus includes a processor and a memory storing computer-readable instructions therein. The computer-readable instructions, when executed by the processor, cause the image processing apparatus to: acquire scan data from a scan data generating unit, the scan data generating unit being configured to generate the scan data by optically reading a sheet being conveyed, the scan data representing a scanned image that includes an image indicative of the sheet, the sheet having a plurality of sides; detect a plurality of edge lines from the scanned image by analyzing the scan data, the plurality of edge lines representing the plurality of sides, respectively; determine whether the plurality of edge lines include a non-linear edge line; and correct, when the plurality of edge lines is determined to include a non-linear edge line, the scan data so that the non-linear edge line is changed to a linear edge line.
