    Photometric Image Processing for High Dynamic Range Displays by Matthew Trentacoste B.Sc., Carnegie Mellon University, 2003 A THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF Master of Science in The Faculty of Graduate Studies (Computer Science) The University Of British Columbia January, 2006 © Matthew Trentacoste 2006 ii Abstract Many real-world scenes contain a dynamic range that exceeds conventional display tech- nology by several orders of magnitude. Through the combination of several existing technologies, new high dynamic range displays, capable of reproducing a range of in- tensities much closer to that of real environments, have been constructed. These benefits come at the cost of more optically complex devices; involving two image modulators, controlled in unison, to display images. We present several methods of rendering images to this new class of devices for reproducing photometrically accurate images. We discuss the process of calibrating a display, matching the response of the device with our ideal model. We then derive series of methods for efficiently displaying images, optimized for different criteria and evaluate them in a perceptual framework. iii Contents Abstract ...................................... ii Contents ...................................... iii List of Tables .................................... vi List of Figures ................................... vii Acknowledgements ................................ ix 1 Introduction .................................. 1 1.1 Image Processing

  • Physical and Perceptual Limitations of a Projector-Based High Dynamic Range Display
    EG UK Theory and Practice of Computer Graphics (2012) Hamish Carr and Silvester Czanner (Editors) Physical and perceptual limitations of a projector-based high dynamic range display Robert Wanat, Josselin Petit and Rafal Mantiuk1 1 School of Computer Science, Bangor University, United Kingdom Abstract High dynamic range (HDR) displays capable of reproducing scenes of high luminance (exceeding 2,000 cd/m2) and contrast (more than 10,000:1) are a useful tool for research on visual performace, image quality or colour appearance. In this paper we describe a projector-based HDR display, giving details on its hardware components and software for driving and calibrating the display. We report the colorimetric properties of the display: the colour reproduction accuracy, colour gamut and local contrast dependent on the size of displayed checkerboard pattern. To verify whether our display can produce local contrast inducing the colour that appears perfectly black to the observer, we conducted an experiment with human observers. Our results indicate that for the test pattern, the effective local contrast of our display (2500:1) is sufficient to produce perfectly black colour, which requires a contrast between 1300:1 and 2400:1.

    ADVANCED METHODS FOR CONTROLLING DUAL MODULATION DISPLAY SYSTEMS by Robin Atkins B.ASc., Queen’s University, 2002 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF APPLIED SCIENCE in THE FACULTY OF GRADUATE STUDIES (Electrical and Computer Engineering) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) March 2012 © Robin Atkins, 2012 Abstract This thesis presents a novel method for controlling a dual-modulation display, also commonly known as a local dimming display. Dual modulation is a technology that improves the contrast and power efficiency of liquid crystal displays (LCDs) by dimming the backlight in image regions that need less light. This is an important improvement as although LCD technology accounts for nearly 90% of today’s displays, it has relatively poor performance in contrast and efficiency. A critical component of a dual modulation display is the control algorithm. Present control algorithms cause an image artifact termed LCD clipping that affects the high spatial frequencies and is highly objectionable to many viewers. In this thesis we introduce an image metric designed to measure this artifact, as we found that existing metrics were not sufficient. The main contribution of the thesis is a new control algorithm for dual-modulation displays that eliminates the LCD clipping artifact, with minimal other tradeoffs in image quality and power efficiency. The new control algorithm requires less computational resources than previous algorithms and no change to display hardware, making it a relatively straightforward upgrade for today’s dual modulation displays. ii Table of Contents Abstract .................................................................................................................................... ii Table of Contents ................................................................................................................... iii List of Tables ..........................................................................................................................

  • High Dynamic Range Display and Projection Systems
    High Dynamic Range Display and Projection Systems by Helge Seetzen A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in The Faculty of Graduate Studies (Interdisciplinary Studies) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) April 2009 © Helge Seetzen, 2009 ABSTRACT The human visual system can perceive five orders of magnitude of simultaneous dynamic range of luminance values. Recent advances in image capture and processing have made it possible to create video content at this level of dynamic range but conventional displays are unable show this rich content. Modern display and projection systems cannot deliver more than three or four orders of dynamic range and are usually limited to lower luminance values than those found in real world environments. This dissertation describes high dynamic range display and projection systems which resolve this bottleneck in the video pipeline and deliver luminance ranges to the limit of human perception. The design of these systems is based on the concept of dual modulation which combines several lower dynamic range image modulation components to achieve higher dynamic range. An overview of relevant perceptual mechanisms, viewer preference with respect to higher dynamic range images, and perceptual validation studies are discussed in addition to several implementation examples of dual modulation systems. ii TABLE OF CONTENTS ABSTRACT .......................................................................................................................................

  • The Luminance of Pure Black: Exploring the Effect of Surround in the Context of Electronic Displays
    The luminance of pure black: exploring the effect of surround in the context of electronic displays Rafa lK. Mantiuka,b, Scott Dalyb and Louis Kerofskyb aBangor University, School of Computer Science, Bangor, UK; bSharp Laboratories of America, Camas, USA ABSTRACT The overall image quality benefits substantially from good reproduction of black tones. Modern displays feature relatively low black level, making them capable rendering good dark tones. However, it is not clear if the black level of those displays is sufficient to produce a “absolute black” color, which appears no brighter than an arbitrary dark surface. To find the luminance necessary to invoke the perception of the absolutely black color, we conduct an experiment in which we measure the highest luminance that cannot be discriminated from the lowest luminance achievable in our laboratory conditions (0.003 cd/m2). We measure these thresholds under varying luminance of surround (up to 900 cd/m2), which simulates a range ambient illumination conditions. We also analyze our results in the context of actual display devices. We conclude that the black level of the LCD display with no backlight dimming is not only insufficient for producing absolute black color, but it may also appear grayish under low ambient light levels. Keywords: Display black level, HDR display, detection thresholds, blackness induction, black limit, pure black, absolute black, real black. 1. INTRODUCTION The quality and aesthetics of displayed images strongly depends on the overall image contrast,1, 2 which is mostly determined by an electronic display black level. Dark tones are abundant in professional photographs and theatrical movies, therefore quality of a display equipment often depends how well these tones can be reproduced.
