Abstract: Devices and methods calibrate an optical scanner by having the scanner scan a calibration surface. The scanner includes a lens causing a distortion of items scanned. During the calibration process, such devices and methods perform a compensation process to remove the distortion from signals output by the scanner when performing the scanning to identify at least one surface irregularity on the calibration surface. After performing the compensation process, the devices and methods adjust the calibration process (using the processor) to apply correction for pixels affected by the surface irregularity. Then, after adjusting the calibration settings, such devices and methods finalize the calibration process and store the scanner settings, again using the processor.

Abstract: A controller controls a scanner unit of an image reading device to read a section of an original document that corresponds to an image reading area specified by a user, when a user instruction for setting the image reading area is received. The controller causes the scanner unit to move to an image reading start position in a sub-scanning direction as specified by a user instruction. When a user instruction for starting image reading is received, the controller causes the scanner unit to start reading the section of the original document from the image reading start position.
