Abstract: An object area containing a text or a graphic is extracted from a document image containing the text or the graphic. Then, on the basis of the extracted object area and stored size information, a cropping area is determined that surrounds the object area with given margins. Further, setting of margins is received. Then, on the basis of the object area and the received setting of the margins, the cropping area is determined. Then, the cropping area determined on the basis of the object area and the size information or alternatively the cropping area determined on the basis of the object area and the setting of the margins is cropped from the document image.

Abstract: An image processing apparatus is connected to an image reading apparatus which reads a read area set on a scanner platen in accordance with a size of a document placed on the scanner platen so as to create image data in which an image of the document is shown. The image processing apparatus includes a document detection section and an instruction section. The document detection section creates, based on the image data supplied from the image reading apparatus, document area information indicative of an area where the document is placed on the scanner platen. In a case where the area indicated by the document area information is not completely encompassed by the read area, the instruction section sets a reread area which completely encompasses the area indicated by the document area information and causes the image reading apparatus to read the reread area.

Abstract: An image processing apparatus includes a document correction section and a display control section. The document correction section carries out rotation processing with respect to a document image so that a first reference direction from a reference side of a document to a side facing the reference side coincides with an upper-to-lower direction of the document image which has been subjected to the rotation processing. Further, before the rotation processing is carried out, the display control section causes the display apparatus to display an image in which the document and a mark indicating the reference side of the document to a user are shown in accordance with the document image. This allows a user to easily predict how the document shown in the document image will be oriented after the document image is subjected to the rotation processing, before the user inputs a command to carry out the rotation processing.

Abstract: A plurality of infrared-light-emitting areas are displayed in a display screen of a liquid crystal display apparatus in a method that allows each of the infrared-light-emitting areas to be distinguished. Then, an image in a direction of a pointed position is captured by an operating device. Based on a result of distinguishing each of the infrared-light-emitting areas and a position of each of the infrared-light-emitting areas, a pointed position on the display screen is calculated. This makes it possible to properly detect the pointed position on the display screen pointed by the operating device, regardless of (i) a distance between the operating device and the display apparatus and (ii) a rotation angle of the operating device around an axis in an image capture direction of the operating device.

Abstract: Based on an area detection signal, a layer separation section outputs a text component of a document, to a feature point calculating section, and generates four layers from a pictorial component of the document to output the generated layers to the feature point calculating section. The feature point calculating section sums feature points extracted for each component. A features calculating section calculates a hash value based on the feature points. A vote processing section searches a hash table based on the hash value, and votes for a reference image associated with the hash value. Based on the voting result, a similarity determination processing section determines whether the document image is similar to any reference image, and then outputs the determination result. Thus, even if the document contains a photograph, accurate matching can be performed.
