PROBLEM TO BE SOLVED: To appropriately read a parameter to be used for image adjustment processing attached to an adjustment document.SOLUTION: An adjustment document is attached with linear images indicating the same tint in a main scanning direction in parallel, and is attached with parameter images indicating parameters for image adjustment processing at a plurality of parts respectively spaced apart in the main scanning direction in a margin area, and an execution control unit causes the adjustment document to be read when an instruction to execute the image adjustment processing is received, determines whether two or more pieces of data corresponding to the plurality of parts match each other out of data obtained by reading a predetermined linear image to be determined, and causes the image adjustment processing to be executed using data corresponding to a normally readable position as any of parts the two or more pieces of which are determined to match each other out of data obtained by reading all linear images attached to the adjustment document, and a parameter indicated by a parameter image attached at a position in the main scanning direction indicated by the normally readable position. |
