Abstract
An image processing device includes: a sensor that reads a print region and a non-print region of a print medium, an image being printed in the print region, the non-print region being a blank area; and a controller that makes shading correction for an output from the sensor, based on a read result from the sensor. The controller sets a patch image printed in the print region to a black reference, sets the non-print region to a white reference, and makes the shading correction, based on properties of the black reference and the white reference at individual locations.
