Screen Size Selection
Screen Size Selection One of the most important decisions in screen selection is to determine the correct size of screen based upon the dimensions of the audience area and the projection format(s) to be used. In some situations, these two questions yield the same answer; in • Ceiling Height—The bottom of the screen should be approximately others they do not and compromises must be made. Here are the key 40–48" above the floor in a room with a level floor and several rows considerations— of seats. In rooms with theatre seating or only one or two rows, • Audience Area—In determining the correct screen size in relation to such as a home theatre, the bottom of the screen should usually be the audience area, the goal is to make the screen large enough so 24–36" above the floor. Try to make sure that the lower part of the those in the rear of the audience area can read the subject matter screen will be visible from all seats. Extra drop may be required to easily, but not so large that those in the front of the audience area position the screen at a comfortable viewing level in a room with a have difficulty seeing the full width of the projected image. high ceiling. • Height—Use the following formulas for calculating screen height for • Projection Format—Once you have determined the correct size of maximum legibility. For 4:3 moving video and entertainment, screen screen for the audience area, that size may be modified height should be at least 1/6 the distance from the screen to the based upon the type(s) of projection equipment to be used. -

Display's the Thing: the Real Stakes in the Conflict Over High Resolution Displays
Display's the Thing: The Real Stakes in the Conflict Over High Resolution Displays Jeffrey Hart and Michael Borrus (c) Copyright Hart and Borrus 1992 I. Display's the Thing: The Real Stakes In the Conflict Over High- Resolution Displays In Akira Kurasawa's film _Rashomon_, several witnesses to a murder tell the story of what they saw. Despite viewing the same event, the witnesses' stories are radically different, so much so that the event itself is ultimately called into question. So has it been with the debate over the next generation of high- resolution video technology. Some look and see a bigger and better television set (high-definition television or HDTV), but usually dismiss what they see as economically (though perhaps not politically) insignificant.1 Others look and see a significant component technology (high-resolution displays or HRD) beginning to pervade a wide variety of electronic systems. They recognize in displays a technological kinship to silicon chips -- an industry with potential strategic significance for commercial and military applications. But the conflict of perspectives should not, as it did in _Rashomon_, cast doubt on the event. The high-resolution display industry is a symbol of a major transformation underway in electronics: that is, the emergence of new component, machinery, and materials technologies driven by commercial, high-volume, integrated micro-systems applications and controlled increasingly by a few integrated producers located outside the United States. This paper argues that the industrial and geographic concentration of the sourcing, development, production, and integration of electronics technologies and systems in Asia portends new patterns of industrial constraint and opportunity, with significant economic and military implications. -

Hall Author Frederick C. Hall is senior plant ecologist, U.S. Department of Agriculture, Forest Service, Pacific Northwest Region, Natural Resources, P.O. Box 3623, Portland, Oregon 97208-3623. Paper prepared in cooperation with the Pacific Northwest Region. Abstract Hall, Frederick C. 2001 Ground-based photographic monitoring. Gen. Tech. Rep. PNW-GTR-503. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 340 p. Land management professionals (foresters, wildlife biologists, range managers, and land managers such as ranchers and forest land owners) often have need to evaluate their management activities. Photographic monitoring is a fast, simple, and effective way to determine if changes made to an area have been successful. Ground-based photo monitoring means using photographs taken at a specific site to monitor conditions or change. It may be divided into two systems: (1) comparison photos, whereby a photograph is used to compare a known condition with field conditions to estimate some parameter of the field condition; and (2) repeat photo- graphs, whereby several pictures are taken of the same tract of ground over time to detect change. Comparison systems deal with fuel loading, herbage utilization, and public reaction to scenery. Repeat photography is discussed in relation to land- scape, remote, and site-specific systems. Critical attributes of repeat photography are (1) maps to find the sampling location and of the photo monitoring layout; (2) documentation of the monitoring system to include purpose, camera and film, w e a t h e r, season, sampling technique, and equipment; and (3) precise replication of photographs. -

Staging Success: Toward a New Performance Model for Live-Event Projection
Photo by Gabor Ekecs Staging Success: Toward a New Performance Model for Live-Event Projection PRESENTED BY IN COLLABORATION WITH As the solid-state revolution in video projection powers on, sophisticated stagers know that all laser projectors are not created equal, and they’re demanding features that deliver not just better total cost of ownership (TCO) but also better imaging, rigging, and video processing performance. INTRODUCTION The best video projectors for live-event staging combine unique light engine and image-processing advances with advanced setup, rigging, and other features that make the staging professional’s job easier and more profitable. But when choosing the right projector for staging and live-event applications, professionals need to carefully compare feature sets and performance criteria. The rental and staging professional should seek out key advanced features—features that are being implemented by the most successful professionals in the field today. This white paper examines those image-quality, motion-processing, rigging, cooling, maintenance, and TCO best practices and features that separate the leaders from the followers among the projector manufacturers serving the live-event staging community. At the Olympic Games Rio 2016 Opening Ceremony, aspects of Brazilian culture and heritage were enhanced with spectacular large- scale mapped visuals carefully programmed and projected from four directions using the PT- RZ31K SOLID SHINE Laser projector and about 110 Panasonic PT-DZ21K2 projectors. Marco Balich, Olympic Ceremonies Executive Producer remarked: “We are very pleased that Panasonic partnered with us in delivering what I consider the best projection ever in an Olympic ceremony.” Stereoscopic floor and screen projection defined the Olympic Games Rio 2016 Opening Ceremony. -
Implementation of Holographic View in Mobile Video Calls
Volume 2, Issue 10, October 2012 ISSN: 2277 128X International Journal of Advanced Research in Computer Science and Software Engineering Research Paper Available online at: www.ijarcsse.com Implementation of Holographic View in Mobile Video Calls * Vignesh.M , SaravanaJothi.M, Computer science and engineering, Computer science and engineering, Anna University, Chennai. Anna University, Chennai. Abstract--- Implementation of holographic video calls in mobile devices using of hologram projectors additional to TFT displays. Here we use hologram projectors for video calls by storing video as holographic images through the method of Computer Generated Holography. Problem statement: Hologram video calls are not in usage, they are simply under research condition. Hologram makes video calls in 3D virtual display. In order to bring hologram usage in mobile phones by means of hologram projectors in the way of computer generated holography. Approach: Computer Generated Holography (CGH) is the method of digitally generating holographic interference patterns. A holographic image can be generated e.g. by digitally computing a holographic interference pattern and printing it onto a mask or film for subsequent illumination by suitable coherent light source. Alternatively, the holographic image can be brought to life by a holographic 3D display (a display which operates on the basis of interference of coherent light), bypassing the need of having to fabricate a "hardcopy" of the holographic interference pattern each time. Consequently, in recent times the term "computer generated holography" is increasingly being used to denote the whole process chain of synthetically preparing holographic light wave fronts suitable for observation. Holographic computer displays for a wide range of applications from CAD to gaming, holographic video and TV programs, automotive and communication applications (cell phone displays) and many more. -
