Abstract: An overhead scanner 1 includes an imaging unit 22 that images a medium S placed on a mount surface 2 to be read from above and a light source 21 that is arranged to be able to irradiate the medium S with light during imaging by the imaging unit 22. A control device 40 of the overhead scanner 1 performs anti-glare control when detecting that the medium S is glossy. This prevents glare from occurring to the user during operation of the overhead scanner 1.

Abstract: During an information-extraction technique, a user of an electronic device may be instructed by an application executed by the electronic device (such as a software application) to acquire images, with different orientations (which are known to the user), of a target location on a document using an imaging sensor, which is integrated into the electronic device. After the user has taken a first image and before the user takes a second image in a different orientation of the electronic device (and, thus, the imaging sensor), the electronic device captures multiple images of the document. Then, the electronic device stores the images with associated timestamps. Moreover, after the user has taken the second image, the electronic device analyzes one or more of the first image, the second image and at least a subset of the images to extract information proximate to the target location on the document.

Abstract: A method of scanning an image of a document with a portable electronic device includes interactively indicating in substantially real time on a user interface of the portable electronic device, an instruction for capturing at least one portion of an image to enhance quality. The indication is in response to identifying degradation associated with the portion(s) of the image. The method also includes capturing the portion(s) of the image with the portable electronic device according to the instruction. The method further includes stitching the captured portion(s) of the image in place of a degraded portion of a reference image corresponding to the document, to create a corrected stitched image of the document.
