Abstract: This invention is directed toward a system and method for scanning a scene or object such as a whiteboard, paper document or similar item. More specifically, the invention is directed toward a system and method for obtaining a high-resolution image of a whiteboard or other object with a low-resolution camera. The system and method of the invention captures either a set of snapshots with overlap or a continuous video sequence, and then stitches them automatically into a single high-resolution image. The stitched image can finally be exported to other image processing systems and methods for further enhancement.

Abstract: Disclosed is an image reading apparatus in which the band width for reading by one scanning is variable in accordance with the original size, the reading mode, etc. R, G, and B image data of the k-th band is successively read in one-band width to store image data R1, G1, and B1 of pixel coordinates X(n, m). Then, the original is fed so as to cause partial overlapping of the (knull1)-th band with a lower predetermined pixel region of the k-th band, and R, G, and B image data of the (knull1)-th band is read in one-band width to successively store image data R2, G2, and B2 of pixel coordinates X(n, mnull). The image data obtained through overlap reading of the k-th band and the (knull1)-th band is averaged to calculate correction image data, which is transferred to a host computer along with along other image data which has not been averaged as read image data. And, it is possible to optimize reading time according to the kind of original, reading mode, etc., without involving a deterioration in image quality.

Abstract: The object of the invention is to easily and simply output a document including an image in a desired layout. A script generation device 10 generates a script used to control a layout of a printer 20, and transfers the generated script to the printer 20. The script includes multiple drawing control commands that individually adjust output positions with regard to a plurality of images to be output in a preset output range. The sequence of arrangement of the multiple drawing control commands specifies the overlapping state of the plurality of images. The script of this construction enables the user to readily define and change the overlapping state and thereby attain a desired layout.

Abstract: An apparatus for bi-directionally rendering an image includes a bi-directional printer (10) having an input (12) which receives data corresponding to the input image. A printhead (14), in accordance with the data, renders the image on a medium (M) in swaths as it passes horizontally over the medium (M) in opposing first and second directions. A medium advance device (16) advances the medium (M) vertically past the printhead (14) between horizontal passes of the printhead (14) in the first direction and horizontal passes of the printhead (14) in the second direction. Horizontal swaths of the image are segmented into a line of columns (20) such that the columns (20) are made up of vertical arrays of pixels. A detector circuit (18) detects for breaks (22) in each of the columns (20) of each swath. Transition regions are defined for columns (20) having no vertical breaks (22) therein. Rendered during the first printing pass are: (i) pixels which are above vertical breaks (22) in each column; (ii) pixels which are above transition regions in each column; and, (iii) a first portion of pixels located in each of the transition regions. Rendered on the reverse printing pass are: (i) pixels which are below vertical breaks (22) in each column; (ii) pixels which are below transition regions in each column; and, (iii) a second portion of pixels located in each of the transition regions.

Abstract: In a digital imaging system including an array of imaging devices that apply an image to a recording medium such as a lithographic printing plate, elimination or reduction of longitudinal imaging artifacts is accomplished by blending the zones imaged by each the devices. In the course of a complete scan of the recording medium, the imaging devices each traverse a series of longitudinal columns of dot locations, and the devices are fired only at appropriate dot locations as determined by the digital image data. By operating adjacent imaging devices such that the zones they would ordinarily cover are blended, artifacts at the boundary between zones (such as seams) are hidden. While sufficient visual disruption to eliminate artifacts is ensured, noticeable visual artifacts are not created as a consequence of the disruption.

Abstract: A method for automatic merging two images having overlapped parts for a handy scanner. The method starts from defining a meaningful sample in a first image using fuzzy logic. Then, a two level searches based on A* algorithm are executed thereafter to find a match point in the second image. After the match point is found, the two images are stitched together using linear interpolation.
