Depaysement, suggested by the well-known surrealist Rene Magritte, has been used for and applied to many media. Application of depaysement through various media such as TV, commercial, and advertisement, attempted to provide interest by deviation from fixed ideas and visual shock, placing common objects in new and strange environment. The study applied screen projection mapping using a transparent screen and objet for different purposes to projection mapping media, applying depaysement to the artwork 'Illusion' in order to suggest visual pleasure, possibility as a new media, and projection mapping using transparent screen and objet. The work cases were suggested by applying expressive methods and effects according to three classifications - modulation of space, combination of conflicting images, and transformation and change of objects - in depaysement, and analyzed by types based on classification of the layout, typography, image, color, and time. Through 'Illusion,' new objet and characteristics of the media are applied and expanded by using projection mapping and depaysement.

Basically, the mis-convergence, which is inevitable in CRT Projection TV. is the degree of deviation of red and blue from green beam. The cause of mis-convergence is the change of magnetic field and electrical characteristic in deflection circuits and convergence amplification circuit. A new and easily implementable mis-convergence compensation algorithm is presented in this paper. The proposed algorithm does not needs any compensation devices. It uses only TV OSD and a remote controller and anyone who wants to compensate can easily correct the mismatch. Through real compensation experiments, it is found that the proposed algorithm is useful and effective one.

교육정보화 사업의 일환으로 각 교실마다 교단선진화 기기라 불리는 장비들이 널리 보급되었다. 그 중에서도 대형 프로젝션 TV의 도입과 초고속 통신망의 발달은 웹과 멀티미디어 시디롬 자료를 교실 안으로 불러들이는 데 큰 역할을 했으며 거의 모든 교과에서 활용되고 있다. 특히 컴퓨터 수업의 경우 일대일 개인지도가 불가능한 다인수 학급에서는 프로젝션 TV로 프리젠테이션하면서 수업을 진행하는 경우가 대부분이다. 그러나 이러한 경우에도 모든 학생들에게 프리젠테이션 화면이 잘 보이지는 않으며 말로만 설명하기에 부족한 부분도 있다. 따라서 본 연구에서는 이러한 문제점을 해결할 수 있는 여러 가지 프로젠테이션 보조 프로그램들의 기능을 분석해보고 컴퓨터 수업을 진행하는 교사들이 효과적으로 프리젠테이션 할 수 있는 프로그램을 설계 개발하고자 한다.

MD (DLP, LCoS) Projection TV is appropriate for large screen display with high definition at a relatively low price and thus, has been popular in the digital TV market. In order to realize high resolutions in the DLP projection TV, we successfully developed the Pixel Enhancement Actuator. Furthermore, it is also required that the contrast ratio of projected video signals onto a large screen should be improved. Therefore, we propose a contrast enhancer which adjusts the amount of projected lights by a dynamic aperture and a attached position sensor.

'꿈의 TV'라고 하는 벽걸이 텔레비전의 양산시대가 2~3년내로 다가오고 있다. 세계 액정시장을 독점하다시피하고 있는 일본의 전자메이커들은 1997년부터 일본에서 방영되는 고선명 화질의 '하이버전' 본방송과 1998년 일본 나가노(장야)에서 열리는 동계올림픽과 때를 맞추어 두께 25mm 이하의 얄팍한 벽걸이TV를 본격적으로 출시할 계획이다. 일본 기업들은 화면의 크기에 따라 20인치 정도까지는 액정디스플레이(LCD), 20~60인치는 플라스마 디스플레이(PDP) 그리고 그 이상은 투사형 프로젝션으로 차별화하여 개발전략을 추진하고 있다.

We have developed new rear LCD Projection TV engine with 3 projection lens. It has high brightness and contrast ratio, however poor cooling conditions. If optical components close to light source, optical components are damaged on high temperature, especially the blue among RGB colors is weakest by heat In this study, a new enhanced cooling method of LCD projection TV with 3 lens is shown: the best suited design of duct and relations between LCD panel and polarizer lifetime with changed area of duct.

With development of media and technology animation are seeking a variety of a genre fusion. I would like to propose a new animation screening method using a projection mapping and a popup book. I redesigned the existing method of watching the animation to a new experience by projecting the image on a three-dimensional structure instead a flat screen. This screening method was inspired by preceded works which were made by the fusion of a projection mapping and a popup book. Through analysis of them, I found the merits, shortcomings and clarified the difference of each works. I called this method "Hybrid Animation Theater" because it is fused the various areas - Theater, Projection mapping, Pop-up book, Animation, and Installations, etc. also studied for its architectural features and design. After I designed a prototype to demonstrate the possibilities, the limitations and shortcomings, I could suggest next research directions.
