An information processing device executes: acquiring a scanned image of a document and a protective sheet that protects the document, the scanned image being obtained by imaging the document and the protective sheet while being conveyed at the same time; acquiring a first length that is a conveying direction length of a predetermined portion of the protective sheet; acquiring a second length that is a conveying direction length of the predetermined portion in the scanned image; and estimating a ratio between a document length, which is a conveying direction length of the document, and a document image length, which is a conveying direction length of the document in the scanned image, based on the first length and the second length.

Information processing device, method, and a non-transitory computer readable storage medium for scanning an image using a protective sheet to estimate a ratio of document lengths, acquired from scanned images, to correct a length of a scanned image or length of a cropped image, based on the ratio

An image processing apparatus includes a processor for acquiring an input image of a document and a periphery of the document, extracting first edge pixels from the input image, detecting a document region based on the first edge pixels, detecting a shadow region from within a predetermined range outside of the document region, extracting noise pixels in the shadow region, detecting the noise pixels, a number of which connected with one another is equal to or more than a predetermined number, as a noise line, and correcting the document region of the input image based on a detection result of the noise line.

Image processing apparatus for detecting a noise line based on noise pixels in the shadow region

An image processing apparatus includes a processor for generating a front-surface image captured of a front surface of a conveyed document and a back-surface image captured of a back surface of the conveyed document, detecting a feature of the conveyed document, determining whether a first end of the front-surface image and a second end of the back-surface image corresponding to the first end are continuous, based on the generated front-surface image and back-surface image and the detected feature, and synthesizing the front-surface image and the back-surface image when it has been determined that the first end and the second end are continuous.
