Abstract: A scanning device and method of forming a scanned electronic image include an imaging sensor and at least one navigation sensor. In the preferred embodiment, the imaging sensor is a linear array of sensor elements, with a two-dimensional navigation sensor array at each end. The scanning device has three degrees of freedom, since position information from the navigation sensors allows manipulation of an image signal from the imaging sensor to reduce distortion artifacts caused by curvilinear scanning. Acceptable sources of the position information include printed matter and contrast variations dictated by variations in the inherent structure-related properties of the medium on which the scanned image is formed. Illumination for optimal operation of the navigation system may be introduced at a grazing angle in some applications or in the normal to a plane of the original in other applications, but this is not essential.

Abstract: A method and apparatus for high speed conversion of tangible source documents to electronic images, and subsequent transmission or storage and retrieval of images, utilizing hybrid signal processing. The system employs a higher bandwidth analog signal for image capture and lower effective bandwidth analog signal for transmission or storage and retrieval, with an intervening digital memory utilized to construct a bitmap of the image to facilitate various dissection and seaming schemes which optimize image content and processing time. The system is designed around a conventional bus structure, and the memory serves as a junction with conventional personal computers, networks, and peripheral devices. In a representative embodiment, a tangible image is captured using a camera producing an analog signal with conventional raster synchronization. The synchronization is stripped from the analog signal, which is digitized for 8-bit grayscale and multiplexed to the memory where the image exists as a bitmap that may be divided into segments. The content is read from the memory, converted to an analog signal, and control signals are added. The control signals include horizontal and vertical sync pulses and interval blanking, a pilot signal to maintain alignment between adjacent segments along seams and to compensate for time-based errors, and calibration pulses to permit instantaneous adjustment of the gray level for each line, ensure accurate image content, and permit display enhancement. The resultant analog signal is stored on a randomly accessible storage medium as one or more frames, transmitted and reassembled, or displayed on a conventional monitor.

Abstract: An image processing apparatus includes a joining-portion processing section for combining partial images that have been read in a divided manner. Focused on partial document data predeterminately specified among a plurality of partial document data stored in an image memory, the joint-portion processing section performs a recognizing operation on the joints, a positioning operation and other operations beginning with the proximity of the specified partial document data. The partial images are then combined together to form one complete image. For example, in the case of copying an original document, which is of a size too large to be copied in one operation, on one sheet of paper in a reduced manner, it becomes possible to eliminate time consuming tasks such as trimming and pasting of the partial documents as well as calculating of the reduction rate. Thus, the efficiency of the operation is improved, and by specifying the partial document data from which the operation is started, it is possible to join the partial images accurately irrespective of the order of inputting the partial documents.

Abstract: An electro-optic imager, used for exposing photosensitive media imagewise, wherein an array, e.g. two or more linear arrays, of light sources are imaged onto a rotating drum, to produce images in bands. Apertures are used to shape the beam energies. The use of two or more linear arrays with interlaced imaging allows aperture shapes to be used which precisely control the region of overlapping exposures. With properly shaped apertures, scanning artifacts (e.g. aliasing) can be nearly eliminated.

Abstract: An electro-optic imager, used for exposing photosensitive media imagewise, wherein a linear array of scanning elements is scanned across a portion of the image, to produce a first region or band of image or information, and then translated in a direction parallel to the linear axis of the scanning elements for another scanning operation to produce a subsequent band, slightly overlapping the previous band. The translation, relative to the photoreceptor, of the scanning array is made very reproducible by establishing the position of a moving member by reference to that of a stationary notched or indented member or members, and the resultant image is made very uniform by adjusting the data controlling the imager within the region of redundant imaging to compensate for minor but known imperfections in this stationary member.

Abstract: A document reading device suitable for use for a personal computer, a facsimile, and a work station or the like, and comprises a reading means for reading the image information provided on a manuscript, a read controlling means for controlling the reading means in such a way that when the reading operation of the reading means is interrupted while reading said manuscript, a predetermined amount of the image information read by the reading means immediately before said interruption occurred, can be reread after the reading operation is restarted, and a processing means for processing both groups of the image information duplicately read by the reading means before and after the interruption thereof, respectively, by modifying them in such a way that a portion of the image information finally output and based upon the image information read by the reading means before the interruption, and another portion of the image information finally output and based upon the image information read by the reading means after the interruption, can be connected to form a continuous configuration. By using this device, an unnatural configuration of reproduced image caused by the interruption of the reading operation and by the restart thereof, can be eliminated.

Abstract: The invention is an improved apparatus for recording an image onto a light recording medium by sequentially recording a plurality of sections onto the light recording medium which constitute the image and further an apparatus for reading previously recorded information disposed on a recording medium (162). The invention utilizes a light position sensor (201) having a target area having a plurality of apertures (604) including at least one line segment coupled to light emitted from a plurality of positions within the light emitting area (120) of the light source (120) used for recording for detecting the position of the light intersecting the target area (201) of the sensor from the light emitting area of the light source and generating at least one signal dependent upon the light intersecting the target area. A controller (13) responsive to the at least one signal, produces at least one correction parameter, sequentially controls the recording and reading of sections (F1-FN) to record or read the image by controlling the position of the light on a light emitting area of the light source as a function of the at least one correction parameter during the recording or reading of each section to cause the light to move to coordinates on the light emitting area of the light source to cause the light to intersect the recording medium at the recording or recorded position coordinates and controls the position of the translator for recording or reading each section.

Abstract: An adaptive image acquisition system employing a hand-held optical scanner or camera is disclosed. The system includes an adaptive camera exposure control system to adjust the camera exposure time to the media's reflectivity characteristics. The system assembles a "filmstrip" of images from compressed video data, wherein redundant image data appearing in successive image frames has been removed. The system employs a correlation process between successive frames to identify the redundant frame information and determined the camera velocity. By adapting the correlation process to the velocity of the camera, the effects of variations in the velocity may be substantially eliminated.
