Determination device, control method for determination device, determination system, control method for determination system, and program

A control method for a determination system including an imaging data acquisition device that captures an image of a printed surface of a printed product to acquire imaging data of the captured image, and a determination device that determines, based on the imaging data acquired by the imaging data acquisition device, a printing method used to produce the printed surface of the printed product for which the image is captured by the imaging data acquisition device, the control method comprising,

• by the determination device:
• selecting a plurality of determination areas included in the captured image from the imaging data acquired by the imaging data acquisition device;
• acquiring determination data based on a line-segment image included in each of the selected plurality of determination areas;
• comparing the acquired determination data between two determination areas, and acquiring, based on a result of the comparison, a determination value for determining a printing method used to produce the printed surface of the printed product;
• and
• determining, based on the acquired determination value, a printing method used to produce the printed surface of the printed product.

A determination device to be used in a determination system including an imaging data acquisition device that captures an image of a printed surface of a printed product to acquire imaging data of the captured image,

• the determination device being configured to determine, based on the imaging data acquired by the imaging data acquisition device, a printing method used to produce the printed surface of the printed product for which the image is captured by the imaging data acquisition device,
• wherein the determination device selects a plurality of determination areas included in the captured image from the imaging data acquired by the imaging data acquisition device,
• acquires determination data based on a line-segment image included in each of the selected plurality of determination areas,
• compares the acquired determination data between two determination areas, and acquires, based on a result of the comparison, a determination value for determining a printing method used to produce the printed surface of the printed product, and
• determines, based on the acquired determination value, a printing method used to produce the printed surface of the printed product.
