Camera

       

      Our 12,000 pixel CCD is a high tech gem!

      This sensor, found on certain observation satellites, gives very fine definition. Very few persons understand the role and relationship of resolution and definition.  The CCD’s higher density and area gives a more detailed image at a given resolution.

      So if we should to display some comparative images,   for example the same documents scanned on an other scan at 600 dpi cannot be zoomed to reveal as fine details as can be seen if the same object was scanned on a Jumboscan at 600 dpi (or maybe lower dpi).

      The camera features a 12,000-pixel monolinear CCD array having 6.5µm pixel size and a 380nm – 1,050nm sensitivity to capture the smallest image detail.

      It hosts 12,000 photodiodes of 6.5 µ2 with a pitch of 6.5 µ2 and a highly effective anti-blooming correction.

      This level of sensitivity, linked to a sampling rate of 36 bits in RGB mode and 208 bits in multispectral mode ensures a fine and wide color spectrum.

      Capture

      From space research to our desktop.

      20 000 x 12 000 pixels producing files of 1.08 Gb.

      JUMBOSCAN has arrived to enable the scanning of the large format media of the new millenium.

      JUMBOSCAN's technology is the same as that running today on observation satellites.

      Only 12 of the most accurate satellites use this technology, Lumiere Technology now brings it for digitization of archives, maps and fine arts !

     

      Scanning Range
       

      The JumboScan™ utilizes a high precision mechanism (1 µm) to enable 1 scan in Bitonal and gray level, and 3 scans in RGB color.  Grayscale scans are truly panchromatic – there is no time conuming need to interpret from color scans.

      Mecanical precision garantees accurate reproduction.  
      Precision is the keyword of JUMBOSCAN:
       

      • The sensor moves on a bed of ball bearings, ensuring positionning to the micron.
      • The step motor is electronically controlled giving 51,200 possible positions for every 360 degree rotation.

    Filters

    A faithful restitution of color, thanks to our exceptional filters :

    The top in dichroic and infrared filters. 

    These dichroic filters, additive and subtractive, with special characteristics have been exclusively developed for JUMBOSCAN. 
     
    The filtration system ensures a high level of resistance to thermal shocks and humidity; enabling prolonged usage with significant modification.

     

    2 options for color scanning with JUMBOSCAN :
     

    RGB & GIS: The traditional 3-channel method known by all imaging professionals.

    Pre-scan Color Calibration

      The JumboScan System employs an Adobe Photoshop Plug-in software module to manage all scanner calibration functions.  Operators may assign specific RGB values to a white background or other specified colors (e.g., R234, G213 and B45 for yellow) on reflective materials as well as to the black background on negative transparencies. A GretagMcBeth DC Colorchecker target is used to initiallyand periodically perform color calibration. 
       

    Color Space Calibration

      Museums scanning fine art and commercial printers scanning press proofs have come to rely on the JumboScan’s CCD 380nm - 1,050nm sensitivity that extends well beyond the 400nm - 750nm visible color spectrum to provide an extraordinarily wide gamut. 

     

      Camera Models

      The Jumboscan camera is available in 3 models: 

      The RGB & GIS models, sold to end user organizations, use 3 bands for image preservation and geometric accuracy. 

      The exclusive 13-band camera, used  by Lumiere Technology to provide multispectral digitizing services, enables spectral quantitative analysis and perfect color qualitative reproduction under any illuminant.

      All models utilize a 12,000 pixel CCD array and software to synchronize the camera and the paired Jumbolux Elliptical Light Projectors.
