Abstract: An image input unit (3) of an authoring device (1) reads the pages of a paper book and creates the images of the pages. A common area extracting section (15) of a border eliminating unit (9) of the authoring device (1) extracts an area common to all the images from the images. The arrangements of at least either the characters or diagrams in the common areas mutually resemble. So as to eliminate the borders outside the common areas of the images, a common area outside eliminating section (19) replaces the colors outside the common areas with the background colors of the common areas. An image output unit (5) of the authoring device (1) outputs the data on the image after the replacement for all the pages as the contents of an electronic book.

Abstract: The invention pertains to a process and device for the optoelectronic scanning of originals. An original (4) is scanned by pixels and lines with the aid of a photodiode line (7). The picture signal values thus obtained for the individual pixels of the scanned lines are read from the integrated shift register (11) of the photodiode-line (7) and fed sequentially to an analogue-digital converter (17). The analogue-digital converter (17) converts only a proportion of the picture signal values from the original (4) to digital picture values for further processing; that proportion is defined by an original extract whose size and shape can be selected. To increase the scanning speed, the picture signal values which are to be converted to digital picture values are read from the shift register (11) at a speed which corresponds to the permissible operating speed of the analogue-digital converter (17) and fed to the latter. Those picture signal values not subject to conversion to digital picture values are read from the shift register (11) at a considerably higher speed.

Abstract: Apparatus is disclosed having document recognition capability for determining the size and location of an original document (10) on a scanner platen (14) before the document is scanned for image capture, and which effects both document recognition and image capture within a single scan cycle. A platen (14) is optically scanned in forward and reverse intrack directions (16, 18), and an electrical information signal characteristic of the optical densities scanned is created. Document recognition is responsive to the electrical information signal produced during the forward direction scan for detecting the boundaries of an original document on the platen. Image capture is responsive to the electrical information signal produced during the reverse direction scan for producing a record of the image on the original document. Magnification is provided for changing the size of the recorded image from that of the image on the original document in part by adjusting the speed of the reverse intrack scan, and is automatically adjustable in accordance with the size of the recording sheet.

Abstract: Apparatus, and accompanying methods for use therein, for locating edges contained within each scan line of a scanned video image and also for locating horizontal boundaries (leading and trailing edges) of a portion of a document contained within the scan line are described herein. Specifically, this apparatus first provides a background value representative of a background level in a scanned image and associated with an incoming pixel value. If the background value exceeds a first reference value, a first signal is generated. If the incoming pixel value exceeds a second reference value, a second signal is generated. Now, an edge transition is detected based upon a pre-defined logical combination of the first and second signals. If such a transition has been detected, such as a leading or trailing edge in either the incoming pixel values or in the background level, a control circuit, illustratively implemented using a programmed array logic circuit and various counters, determines if the edge transition is associated with a valid leading or trailing edge, i.e. whether the transition itself is followed by a pre-determined number of similar pixel values. If a valid leading or trailing edge is detected, then the control circuit generates appropriate signals to store the horizontal pixel address of the incoming pixel value as a leading or trailing edge. In addition, once all the leading and trailing edges have been determined for a current scan line, then the leading/trailing edge pair having the widest spacing is selected as being the designated leading and trailing edges (horizontal boundaries) of a portion of a scanned document located within the current scan line.
