Abstract:
An imaging apparatus for use with a subject may include a light source structured to irradiate the subject with a yellow light, a magenta light and a cyan light at a delayed illumination timing; and a plurality of photodetectors structured to detect the intensity of the light coming from the subject when the yellow light is irradiated, the intensity of the light coming from the subject when the magenta light is irradiated, and the intensity of the light coming from the subject when the cyan light is irradiated.
Abstract:
A viewing aid includes a camera, a viewing surface within a field of view of the camera, a memory, a display, and software programmed to track a tracking element within the field of view. Viewing material is placed on the viewing surface. The camera, viewing surface, and material all remain substantially stationary. The camera captures and stores an initial image of the material in the memory. The software then tracks the location of a tracking element within the field of view then maps the location to a portion of the initial image in memory using an X-Y coordinate system, and/or identifies character elements of the material adjacent the tracking element then maps the character elements to corresponding character elements of the initial image in memory. An enhanced image is then displayed on the display corresponding to the mapped portion of the initial image.
Abstract:
A document camera system includes a page-turning device, an image pickup unit, a specification unit, a recognition unit, a determination unit and a notification unit. The page-turning device turns pages of a book. The image pickup unit picks up an image of each turned page. The specification unit specifies a page number portion in the image picked up by the image pickup unit. The recognition unit recognizes characters in the page number portion specified by the specification unit to identify a page number. The determination unit determines correctness of the order of the page numbers identified by the recognition unit. The notification unit notifies a user of an error when the determination unit determines that the order of the page numbers is incorrect.
Abstract:
A image reading apparatus includes a first placement unit, a second placement unit, a first reading unit, a second reading unit, a rotating mechanism, and a switch-over mechanism that switches over the first placement unit and the second placement unit between a horizontal state and an inclined state. The rotating mechanism rotates the first reading unit and the second reading unit, so that, in the horizontal state, the first image reading unit and the second image reading unit read a medium placed on the first placement unit and a medium placed on the second placement unit respectively, and, in the inclined state, the first image reading unit and the second image reading unit read a medium placed on the second placement unit and a medium placed on the first placement unit respectively.
Abstract:
An overhead image reading apparatus includes an image-capturing unit that captures an image of a medium to be read placed on a placement surface from above, a light source capable of irradiating the medium with light, and a brightness controller that gradually alters brightness of the light source at least when the light source is turned on or when the light source is turned off. The overhead image reading apparatus may gradually alter the brightness by duty control on current supplied to the light source. Or, the overhead image reading apparatus may gradually alter the brightness by controlling a current value supplied to the light source. Alternatively, the overhead image reading apparatus may include a variable aperture between the light source and the placement surface to gradually alter the brightness by controlling an opening area of the aperture.
Abstract:
Disclosed is a magnification device for use by blind and/or low vision individuals. The device includes an X-Y table upon which an item to be magnified can be placed. A stationary camera arm and a pivotal monitor arm are oriented over the X-Y table. The monitor arm includes a video monitor pivotally mounted at its distal end. The camera arm also includes two laterally disposed lighting arms. A series of controls are provided along a lower edge of the monitor via a mounting bracket.
Abstract:
An image reading unit includes an image reading section that reads an image of a document in a one-dimensional direction by one-dimensionally aligned imaging elements, a light source that irradiates an image reading region by the image reading section with light, and a rotation head that holds the image reading section and the light source in a manner that the image reading section and the light source are rotatable relative to the document about a rotation axis which is parallel to an alignment direction of the imaging elements.
Abstract:
A document camera includes: n (n≧2) imagers; a temporal storage that temporarily stores m sets of image data captured by m (1≦m≦n) imagers among the n imagers; an image processor that performs predetermined image processing according to the number of image data sets m on the m sets of image data stored in the temporal storage; and an output image data output unit that outputs output image data to a display apparatus, the output image data being a single output image data set produced in the predetermined image processing.
Abstract:
A document scanner (10) includes an input tray (30) for holding documents (20) and an input image capture device (40) for capturing images of the documents (20)in the input tray (30) prior to transporting the document for imaging; an output tray (150) for holding documents (20) after the documents (20) exit the scanner; an output image capture device (140) for capturing images of the output tray; an image processor for determining characteristics of the output tray or characteristic of the documents (20) before imaging and after the documents (20) exit the scanner; and scanner functions are modified based on the output tray characteristics or the document characteristics.
Abstract:
Embodiments of scan stand systems or kits for positioning a document or other object to be imaged or scanned in relation to an imaging device are described. Also described are embodiments of systems for video conferencing/telephony/scanning and optical projection functions.
