A technique includes acquiring data representing a first image produced by electronically scanning a page against a background. The first image contains a non-uniform background content due at least in part to a variation introduced by the background being non-uniform. The technique includes extracting an image of the page from the first image, wherein the extraction includes characterizing the background content of the first image; identifying candidate pixels associated with the page based at least in part on the characterized background content; and based at least in part on the identified candidate pixels and a model for a boundary of the page, determining the boundary of the page.

An apparatus for scaling images is provided that includes at least two input ports, a scaling component coupled to the at least two input ports, the scaling component including a plurality of scalers, the scaling component configurable to map any scaler to any input port of the at least two input ports and configurable to map more than one scaler to any input port, and a memory coupled to the at least two input ports and to outputs of the plurality of scalers, the memory configured to store image data for each input port and scaled image data output by the plurality of scalers.

A computing device is configured to generate a graphical user interface (GUI) that allows an end-user to search for particular document or documents within a large collection of documents. The GUI provides a view of the overall document collection and affords the end-user the ability to reduce the number of visual document thumbnails by means of keyword search. When the end-user identifies a candidate among the reduced number of thumbnails, the end-user may select the page view of the candidate document and conduct further review. If the selected candidate is not the target document, the end-user may select adjacent documents to seamlessly transition between reading and searching. An advantage to this approach is that the visual qualities of the documents, such as images, graphical layout, and color, among others, may be incorporated into the search process. Searching for a particular target document is, thus, expedited.

An electronic device includes a display, a processor and a memory that stores an image file having image data. The image data includes at least one object and metadata. The metadata includes information about an area corresponding to the at least one object and identification information of the at least one object. The processor outputs the area of the image file, which includes the identification information corresponding to a user input as a thumbnail of the image file, in the display in response to the user input.

An image processing apparatus includes a memory and circuitry. The circuitry is configured to calculate a pixel scale factor for each of pixel positions in a main scanning direction of an input image for a line based on a magnification. The circuitry is configured to store, in the memory, the pixel scale factors calculated for the line in order of pixel position. The circuitry is configured to read, in parallel, N-number of pixel scale factors of the pixel scale factors for the line in order of pixel position from the memory, in synchronization with parallel reading of N-number of pixels in the main scanning direction from the input image, where N represents an integer not smaller than 2. The circuitry is configured to multiply, in parallel, the N-number of pixels read from the input image by the respective N-number of pixel scale factors read from the memory.

At the time of copying a smaller document and a larger document on output sheets having the same size, in a first case where a first document is smaller and a second document is larger, a printing control unit analyzes a content of the second document, and copies the first document and the second document on output sheets having sizes corresponding to the analysis result. In a second case where the first document is larger and the second document is smaller, a content of the first document is analyzed, and the first document and the second document are copied on output sheets having sizes corresponding to the analysis result.

Embodiments of the present disclosure include methods and systems for altering an orientation of a logical cell at a multi-function device. In one embodiment, before rasterization, a user submits a job having multiple pages and an initial instruction to arrange n number of pages on a single medium. Each page has a pre-defined orientation. Another instruction is received to alter a pre-defined orientation of a selected page in the corresponding logical cell. An N-up operation is performed to arrange the n number of pages on the single medium. Each page arranged on the single medium represents a logical cell. While performing the N-up operation, the pre-defined orientation of a logical cell corresponding to the selected page is altered. The logical cell with the altered orientation is printed and the remaining logical cells with respective pre-defined orientation are printed on the single medium.

A high-definition (HD) fax system routes outbound fax job requests including a high-resolution component to appropriate destinations, including among HD-enabled receiving devices and conventional fax devices. If it is determined that a fax destination is not HD-enabled, such as a conventional fax device, the high-resolution component of the outbound fax job request may be rendered as a low-resolution fax. The low resolution fax may be transmitted via a public switched telephone network (PSTN). On the other hand, if it is determined that a fax destination is HD-enabled, a determination may be made whether the HD-enabled fax destination is color enabled, and the high-resolution component may be rendered as either a high-resolution monochrome fax or a high-resolution color fax.

A drone autonomously operates to track an object, track an object while being stealthy and/or observe the details of an object while maintaining communication at a rate equal to or greater than a threshold. A drone may operate to maintain the image of an object at or above a predetermined resolution in an image captured by a camera mounted on the drone and to maintain a wireless communication rate equal to or greater than a threshold rate. A drone may operate so that the sound intensity level caused by the operation of the drone is less than or equal to a sound intensity level threshold as perceived by an object (e.g., person, target, suspect) being tracked.

A scanner has a processor configured to output, when a document is scanned, an original image, which is the image generated by scanning the document, and an extracted image, which is an image extracted from part of the original image, as a single file.
