Abstract:
An image reading apparatus that reads a first image and a second image which were photographed on a microfilm side by side in the width direction of the microfilm. The image reading apparatus has a reading device which reads the images on the microfilm, a parameter setting device which sets separately a first image processing parameter for the first image and a second image processing parameter for the second image, and a control device which controls the reading device to read the first image in accordance with the first image processing parameter and to read the second image in accordance with the second image processing parameter.
Abstract:
An image display apparatus has an optical system including a movable mirror for projecting the image of an image bearing member, a screen for displaying the image projected by the optical system, an image sensor fixed in the vicinity of the screen but outside the image projecting optical path toward the screen, and a moving mechanism for moving the mirror between a display position for projecting the image onto the screen and a reading position for projecting the image onto the image sensor.
Abstract:
A digital microform imaging apparatus, comprising a chassis, a fold mirror supported by the chassis and including a reflecting surface for directing light from a first substantially vertical optical axis to a second substantially horizontal optical axis, a microform media support structure supported at a location intersected by the first optical axis, a first carriage supported for movement along a trajectory that is substantially parallel to the second optical axis, an area sensor supported for movement along the second optical axis, the area sensor further supported by the first carriage for rotation about an axis parallel to the second optical axis and a lens supported for movement along the second optical axis, the lens positioned between the area sensor and the fold mirror, a first motor mounted to the first carriage and linked to the area sensor for rotating the area sensor between at least two positions for obtaining portrait and landscape images of a microform media.
Abstract:
A method for reading analogue and/or digital data, which are stored in fields on a microform, includes using a device for accessing the microform, which device is connected to a data processing system via a hardware interface. In order to make it possible to further process the data acquired by the device in a conventional personal computer, the analogue and/or digital data stored on the microform are represented by a control unit of the device of the data processing system as if the microform were a conventional replaceable data storage medium. Finally, the microform has a structure that allows the data stored thereon to be read quickly and is also suitable for the long-term and secure archiving of digital data.
Abstract:
This invention has as its object to obtain a high-quality read image from which dust or scratches have been removed by an image reading apparatus which reads image information on a transparent original by synchronously scanning a light source unit and image reading unit. To this end, upon reading a transparent original, infrared LED chips on a dust/scratch detection LED substrate and a transparent original illumination lamp are turned on to make alignment between the LED substrate and the image reading unit, and dust/scratch detection image information is obtained by synchronously moving the light source unit and image reading unit in the subscanning direction.Subsequently, alignment between the transparent original illumination lamp and image reading unit is made, and image information of the transparent original is obtained by synchronously moving the light source unit and image reading unit in the subscanning direction.
Abstract:
Apparatus for remotely viewing and scanning microfilm at a first location, while controlling the viewing and scanning from a remote location, including a viewing and scanning device for generating a video feed and subsequently scanned images of the microfilm, a host computer at the first location in communication with the viewing and scanning device to receive the video feed and the scanned images, a user's computer at a remote location in communication with the host computer to receive the video feed and the scanned images from the host computer, and a virtual film movement control at the user's computer to control the movement of the microfilm at the first location. A virtual camera control at the remote location controls the camera of the viewing and scanning device.
Abstract:
A line CCD scanner includes a photo film passageway in which developed photo film is positioned. A light source illuminates an image in the photo film positioned in the photo film passageway. A line CCD reads the image being illuminated. A mask member is secured to the photo film passageway. The image is positioned at the mask member. A mask slit is formed in the mask member, for directing light from the light source toward the photo film. The mask slit has a small width with reference to a predetermined direction. Furthermore, a protrusion portion is disposed on the mask member to extend in the width direction of the photo film, provided with the mask slit formed in a middle thereof, for flexing the photo film in the longitudinal direction to remove flexing in the width direction.
Abstract:
A system and method for storing documents in human and machine readable format. A laser scanner is used to write de-magnified visual copies and digital records of the documents in an optical recording medium. A table of contents and record headers are provided to ease document retrieval. The optical recording medium is made of materials which can be written directly by the laser scanner without the need for post-writing processing. The direct write characteristic allows immediate retrieval, and allows additional documents to be added to the optical recording medium at later times. The documents are retrieved from the optical recording medium by either magnifying the visual copies or by regenerating the documents in visual form using the digital information.
Abstract:
A film image retrieval and scanning apparatus having split first and second optical paths with each optical path being precisely aligned with the other, and each path containing coupled zoom optics. The first path projects a film image onto a first scanner array in the first path to provide a real time display of the image on a TV monitor. The second optical path projects an image onto a second scanner array, which may have a higher resolution than the first array to provide an analog signal that is converted to a digital signal of the image that may be stored, or transmitted on a network, or both. The first scanner provides a real time image and serves as a viewfinder that can be used to locate the proper position of an image; thus ensuring that the image will be aligned with the second array so that it can be scanned by the second scanner array when desired.
