    • An accurate characterization of CRT Monitor (I) verifications of past studies and clarifications of Gamma 

      Katoh, Naoya; Deguchi, Tatsuya; Berns, Roy (The Optical Society of Japan, co-published with Springer-Verlag GmbH, 2001-09)
      CRT monitors are widely used to view images on the Internet. The color images on the computer graphic display can be printed out or displayed on other monitors through the Internet, and color matching between the original ...

    • An accurate characterization of CRT monitor (II) proposal for an extension to CIE method and its verification 

      Katoh, Naoya; Deguchi, Tatsuya; Berns, Roy (The Optical Society of Japan, co-published with Springer-Verlag GmbH, 2001-09)
      According to the ICC specification that is widely used for storing colorimetric characteristics of imaging devices for the current color management systems (CMSs), CRT monitor characteristics can be described by the tone ...

    • Accurate color reproduction of CRT: displayed images as projected 35mm slides 

      Fairchild, Mark; Berns, Roy; Lester, Audrey (International Society for Optical Engineering (SPIE), 1996-01-01)
      Accurate color reproduction of images presented on a computer-controlled CRT display as projected 35-mm transparencies is a complicated procedure requiring the characterization and control of several imaging processes and ...

    • Cathode-ray-tube to reflection-print matching under mixed chromatic adaptation using RLAB 

      Berns, Roy; Choh, Heui-Keun (International Society for Optical Engineering (SPIE), 1995-10-01)
      Color-appearance models are used to relate chromatic stimuli viewed under one set of viewing and illuminating conditions to a differing set such that when each stimulus is viewed in its respective conditions, the stimuli ...

    • Colorimetric characterization of a computer-controlled liquid crystal display 

      Day, Ellen; Taplin, Lawrence; Berns, Roy (John Wiley & Sons, Ltd, 2004-10)
      A new method was used to characterize computer-controlled liquid crystal displays (LCDs). The characterization, which was performed to enable colorimetric image display, included channel independence, spatial independence, ...

    • Colorimetric characterization of a desktop drum scanner using a spectral model 

      Berns, Roy; Shyu, M.J. (International Society for Optical Engineering (SPIE), 1995-10-01)
      A desktop drum scanner was colorimetrically characterized to an average CIELAB error of less than unity for Kodak Ektachrome transparencies and Ektacolor paper, and Fuji Photo Film Fuflchrome transparencies and Fujicolor ...

    • A critical review of spectral models applied to binary color printing 

      Wyble, David; Berns, Roy (John Wiley & Sons, 2000-02)
      A critical review of binary color printing models is presented. The goal is to provide an understanding of the application of color printer models as a component for device profiles within a color management system. A short ...

    • Estimating black-level emissions of computer-controlled displays 

      Berns, Roy; Fernandez, Scot; Taplin, Lawrence (John Wiley & Sons, Ltd, 2003-10)
      It is quite common for computer-controlled displays to emit light in image areas set to digital values of zero, referred to as their black level. This is expected for liquid-crystal displays and also can occur for cathode-ray ...

    • Hierarchical approach to the optimal design of camera spectral sensitivities for colorimetric and spectral performance 

      Quan, Shuxue; Ohta, Noboru; Berns, Roy (The Society for Imaging Science and Technology and the Society of Photo-Optical Instrumentation Engineers, 2003-01)
      The optimal design of spectral sensitivity functions for digital color imaging devices has been studied extensively. This paper analyzed the important requirements for designing sensor sensitivity functions. A hierarchical ...

    • Methods for characterizing CRT displays 

      Berns, Roy (Elsevier Science B.V., Amsterdam, 1996-05)
      Computer-controlled CRT displays can be described by a two-stage model. The first stage consists of a linear transformation matrix relating radiometric scalars of each channel with either spectral radiance or tristimulus ...

    • Predicting the image quality of color overhead transparencies using a color-appearance model 

      Tanaka, Toru; Berns, Roy; Fairchild, Mark (The International Society for Optical Engineering (SPIE) & The Society for Imaging Science & Technology (IS&T), 1997-04-01)
      The color-image quality of color overhead transparencies depends on properties of the imaging system used to create the transparency and illuminating and viewing conditions of the transparency such as the projector's ...

    • Relative significance of the terms in the CIEDE2000 and CIE94 color-difference formulas 

      Melgosa, Manuel; Huertas, Rafael; Berns, Roy (Optical Society of America, 2004-12)
      CIELAB-based color-difference formulas are used to improve the prediction of visually perceived color differences through the introduction of various corrections to CIELAB. In our study we analyze the relative importance ...
