Abstract:
An imaging system includes a line-scan camera (8) having an image line in an planar imaging beam path and a depth of focus. Line forming optics are arranged between at least two arrays of LEDs (4,6) and the image object so as to form two respective illumination stripes in two planar illumination beam paths (5,7). The planar imaging beam path (9) is located between the two or more planar illumination beam paths (5,7). The planar imaging beam path (9) and the two planar illumination beam paths (5,7) preferably intersect proximate to the far depth of focus of the camera. The image line and illumination stripes are parallel across an image area, which may comprise a transport device, such as a conveyor. The non-coplanar planar illumination beam paths provide maximum overlap at the farthest depth of field where illumination is most needed and diverge closer to the camera.
Abstract:
A method and system for optimizing the conversion of analog records to digital format are disclosed. The method includes: examining related analog records to be archived, analyzing an information detail selected from a worse case sample of the examined analog records, imaging the information detail with a digital imaging device (10) for a pixel sequence, optimizing the resolution of the pixel sequence, capturing the analog record with the digital imaging device (10), and saving the captured record as a digitally archived record. The steps of capturing the analog record and saving the captured record can be repeated for each page within the related analog records without having to re-optimize the resolution of the digital image prior to recording and saving. The pixel sequence is based on a pixel-per-line sequence (PPLS) ranging from 3 pixels to 10 pixels, and is especially based on a PPLS range of 3-4 pixels.
Abstract:
A process is useful for making stage sets or paintaing other large objects and surfaces in accordance with corresponding models. The image data are input and possibly processed on screen by a computer-assisted operation, converted into a digital data structure and stored. When required, the digital data are retrieved, converted into control signals for the corresponding nozzles (16, 17) and then represented in dot form on the surface to be painted (3). When making stage sets, a portal frame (8) is used, which can be moved on portal rails (6, 7) arranged along the longitudinal edges of the set holder (4). A nozzle carriage (14) can be moved perpendicular to the portal frame (8). A central processing unit (25) with display and keyboard and other processors ensure precise control of the corresponding nozzles by the output electronics (18) associated with the nozzles (16, 17).
Abstract:
An image capturing apparatus includes an illumination member to selectively provide a target reference to guide placement of the target within a field of view of an image capturing m ember. The illumination m ember may illuminate the at least one reference guide pattern in an illumination-on mode. The illumination member may also disable the target reference by not illuminating the at least one reference guide pattern in an illumination-off mode.
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:
A system and method for processing an image of a document is disclosed. The method includes receiving at least one predetermined document parameter of the document. An image of the document is previewed on a display using a camera. The display provides a visual indication of a defect in the image based on the preview. A processor proposes a procedure to minimize the defect in the image. A user adjusts the camera in response to the proposal. The processor processes the image of the document.
Abstract:
A portable camera for recording and displaying an image of an object such as printed paper wherein the camera is arranged to be positioned on an object to be recorded wherein the cameras is provided with an outer lower surface which is arranged to be in contact with the object if the camera is positioned on the object, a light sensitive sensor for obtaining an image of at least a portion of the object, a display and processing means for processing the image obtained by means of the sensor and for displaying at least a portion of the recorded image on the display in a possible magnified form, wherein the camera is provided with at least one lighting unit for lighting the object to be recorded when the camera is positioned on the object, wherein the camera is arranged such that light rays of the at least one lighting unit which are, in use, submitted to the object are directly submitted to the object, possibly via a mirror and/or a lens wherein the lighting unit is arranged within the camera such that if the object which is recorded would be a flat mirror whereon the camera is positioned for recording the flat mirror, the lighting unit is located outside a viewing field of the sensor which viewing field is formed in combination with the flat mirror.
