Abstract
According to the present disclosure, a page-turned bound medium is read continuously to acquire images, it is determined whether there is any image without the appearance of a foreign object out of the images corresponding to the same page, when it is determined that there is any image without the appearance of the foreign object, the image without the appearance of the foreign object is acquired as an output image, and when it is determined that there is not any image without the appearance of the foreign object, the images corresponding to the same page are combined to acquire the output image.
Claims17
An overhead image-reading apparatus comprising:
- an image acquiring unit configured to cause an image-reading unit to read continuously a page-turned bound medium to acquire images;
- a detection determining unit configured to determine whether there is an image without an appearance of a foreign object out of the images of the same page;
- and
- an output image acquiring unit configured to:
- when the detection determining unit determines that there is an image that does not contain an appearance of a foreign object, acquires the image that does not contain an appearance of a foreign object as an output image, and
- when the detection determining unit determines that all images contain an appearance of a foreign object, combines portions of two or more images of the same page to acquire the output image, the portions of the two or more images being portions of the same page that is not turned and that do not contain an appearance of a foreign object.
An image-processing method executed by an overhead image-reading apparatus, the image-processing method comprising:
- reading continuously a page-turned bound medium to acquire images;
- determining whether there is an image without an appearance of a foreign object out of the images of the same page;
- and
- when it is determined that all images contain an appearance of a foreign object, combining portions of two or more images of the same page to acquire the output image, the portions of the two or more images being portions of the same page that is not turned and that do not contain an appearance of a foreign object.
A computer program product having a non-transitory tangible computer readable medium including programmed instructions for causing, when executed by an overhead image-reading apparatus,
- the overhead image-reading apparatus to perform an image-processing method comprising:
- reading continuously a page-turned bound medium to acquire images;
- determining whether there is an image without an appearance of a foreign object out of the images of the same page;
- and
- when it is determined that all images contain an appearance of a foreign object, combining portions of two or more images of the same page to acquire the output image, the portions of the two or more images being portions of the same page that is not turned and that do not contain an appearance of a foreign object.
