Abstract
An image processing device includes a controller and an image acquiring device. The controller acquires, by using the image acquiring device, a document image including a first image, a second image, and a third image generated sequentially by using a first sensor, a second sensor, and a third sensor, respectively, the first sensor, second sensor, and third sensor being image sensors that are arranged in accordance with a predetermined order relationship along a conveying direction of a document and read color components of three colors different from each other, compares the first image, second image, and third image with each other, and determines whether the document image contains a color shift from the document, based on a result of the comparison.
Claims7
An image processing device comprising:
- a controller;
- and
- an image acquiring device, wherein
- the controller
- acquires, by using the image acquiring device, a document image including a first image, a second image, and a third image generated sequentially by using a first sensor, a second sensor, and a third sensor, respectively, the first sensor, second sensor, and third sensor being image sensors that are arranged in accordance with a predetermined order relationship along a conveying direction of a document and read color components of three colors different from each other,
- compares the first image, second image, and third image with each other, and
- determines whether the document image contains a color shift from the document, based on a result of the comparison.
A control method for an image processing device, the method being executed by one or more processors and comprising:
- acquiring, from an image acquiring device, a document image including a first image, a second image, and a third image generated sequentially by using a first sensor, a second sensor, and a third sensor, respectively, the first sensor, second sensor, and third sensor being image sensors that are arranged in accordance with a predetermined order relationship along a conveying direction of a document and read color components of three colors different from each other;
- comparing the first image, second image, and third image with each other;
- and
- determining whether the document image contains a color shift from the document, based on a result of the comparison.
