    In this paper, we propose a new scene change detection method using multiple histograms. The proposed method produces multiple histograms of split blocks for consecutive frames. Then, it computes the optimal threshold value using automatic thresholding based on the Otsu method and decides whether the scene change occurs or not using the difference between threshold values in successive frames.

    The red-emitting phosphor [K0.8Y0.65Eu3+0.08 ][Mo0.2W0.8O4] was produced by a solid-state method. Through XRD spectra, DTA-TG and photo-luminescent analysis, the possible reaction path and the emission mechanism of the phosphor were mentioned, and the partial Judd-Ofelt parameters and quantum efficiency of Eu...

  • Compound Speckle Characterization Method and Reduction by Optical Design

    Publication Year: 2012 , Page(s): 132 - 137

    Speckle and the compound speckle can be reduced by angle diversity. In laser projection displays, simple, low cost and efficient speckle reduction techniques require smart optical design . Using a MEMS scanner together with a condenser lens, laser beams with different illumination angles are obtained on the diffuser surface with low speckle contrast ratio (CR). After homogenizing within a rod inte... View full abstract»

    The trade-off between the aliasing in integral imaging (II) and the level of interference among adjacent elemental images is mathematically studied in this paper. It is then shown that the multiple-access techniques successfully used in communication systems, e.g. frequency-division multiple access (FDMA), can be invoked to ease the trade-off. Implementation of spatial FDMA technique in three-dime... View full abstract»

  • A New Color Breakup Measure Based on Color Difference Between Fields and Contrast to the Surrounding

    Field-sequential-color displays can have low power consumption and high spatial resolution, but can suffer from annoying color breakup. Various approaches to suppress color breakup have been presented in recent literature. However, a suitable color breakup measure is necessary to compare the performances of those approaches, and is also helpful for quick evaluation of algorithms and parameter sett...

  • Detection of Physical Defects in Full Color Passive-Matrix OLED Display by Image Driving Techniques

    Publication Year: 2012 , Page(s): 154 - 161

    Access to display pixels for the purpose of identification of a defect in a sealed display is difficult. Thus, it will be useful to investigate the physical defects in a passive-matrix organic light-emitting diode (PMOLED) display, such as electrically open anode or cathode, shorted anode or cathode or pixel short by driving the display as red, blue, green, white, or black image and observing the ...

  • Comparison of the EMI Performance of LED PWM Dimming Techniques for LED Video Display Application

    Publication Year: 2012 , Page(s): 162 - 165

    Light-emitting diode (LED) video displays enclose thousands of LEDs which create the resulting image. LED intensity is regulated using pulse width modulation (PWM). Though the individual LED current is small, the total current consumed is large. Simultaneous switching of a large number of LEDs dimmed by PWM can cause serious electromagnetic interference (EMI). Three LED PWM dimming techniques have... View full abstract»

  • Detailed Eye-Safety Analysis of Laser-Based Scanned-Beam Projection Systems

    Recently, an analysis of current scanned-beam laser projection systems was presented and showed that the maximum achievable Class 2 eye-safe luminous flux levels are fundamentally limited by the nature of the projection architecture. In this paper, an improved estimate for the maximum Class 2 eye-safe luminous flux is derived by considering unidirectional and bidirectional scan patterns. It is sho... View full abstract»

    Two designs of high color purity RGB color filter (RGB-CF) using Fabry-Perot etalon were proposed. First, various transmission spectra for corresponding pixel arrays were achieved by optimizing the orientation of fixed polymerized liquid crystal polymers with high birefringence. The designed high color purity RGB-CF is believed to have potential for display applications. Second, three primary tran... View full abstract»
