Manual processing to make illusion-image of Digital Animation consists of handicraft technology indeed, such as an animation process, image addition and image revision etc.. This thesis asserts that is acquiring new art concept, resuscitating the craftsmanship of art in this digital manufacturing process. To concrete this, this paper consists of the following steps. First, reproduction and mixture in a Film. In art history which have emphasized 'Aura' of an, Reproduction by machine became that can not avoid. Various pictorial information and added images stored by digital become having an opportunity that can do easily a new film-work with reproduction and mixture It is the second rank, extension of an area of Digital Animation. Now, Digital Animation is recognized as a new creative art through illusion of meta-realism. Consequently, the process of Digital Animation is acquiringing the possibility as a new art of Digital Animation, showing the characteristics of a new media art that reconstructs imagination which past media arts could not achieve.

The main purpose of a spatial audio system is to give a listener the same impression as if he/she were present in a recorded environment. A dummy head microphone is generally used for such purposes. Because of its human-like shape, we can obtain good spatial sound images. However, its shape is a restriction on its public use and it is difficult to convert a 2-channel recording into multi-channel signals for an efficient rendering over a multi-speaker arrangement. In order to solve the problems mentioned above, a spatial audio system is proposed that uses multiple microphones on a rigid sphere. The system has five microphones placed on special points of the rigid sphere, and it generates audio signals for headphone, stereo, stereo dipole, 4-channel, and 5-channel reproduction environments. Subjective localization experiments show that front/back confusion, which is a common limitation of spatial audio systems using the dummy head microphone, can be reduced dramatically in 4-channel and 5-channel reproduction environments and can be reduced slightly in a headphone reproduction.

This study is to analyze and evaluate copyright protection environment in digital reproduction and transmission, find out problems involved. and suggest recommendations for improvement. Data was collected 50 libraries to which digital reproduction and transmission is permitted under the Copyright Act were surveyed to examine the present states of digitalization and the systems employed. Also, library users, sampled from 5 libraries carrying out all the 6 technical measures obliged by the Copyright Act, were surveyed to examine their use of digital materials and perception on the copyright. After reviewing descriptive statistics, frequency and cross-tabulation analysis were made. The results of the analysis are most of the libraries. except for the industry university libraries, have implemented digital library systems, but the introduction rate of both digital reproduction system and transmission system are high (68.0% and 84.0%. respectively), while that of copyright protection system was low (26.0%). 84.0% of the libraries surveyed digitalize the full text, but the Libraries have digital collection less than 5,000 items, and only 33.3% of them digitalize materials with securing the copyrights. Regulations on copyright protections are not obliged properly. and it appeared that not only users' perception and perception of copyright as well as their use of electronic books are relatively low.

The purpose of this thesis is to examine ontology of digital photo image based on a Simulacre concept of Gilles Deleuze & Jean Baudrillard. Traditionally, analog image follows the logic of reproduction with a similarity with original target. Therefore, visual reality of analog image is illuminated, interpreted, and described in a subjective viewpoint, but does not deviate from the interpreted reality. However, digital image does not exist physically but exists as information that is made of mathematical data, a digital algorithm. This digital image is that newness of every reproduction, that is, essence of subject 'once existing there' does not exist anymore, and does not instruct or reproduce an outside target. Therefore, digital image does not have the similarity and does not keep the index instruction ability anymore. It means that this digital image is converted into a virtual area, and this is not reproduction of already existing but display of not existing yet. This not-being of digital image changes understanding of reality, existence, and imagination. Now, dividing it into reality and imagination itself is meaningless, and this does not make digital image with technical improvement but is a new image that is basically completely different from existing image. Eventually, digital image of the day passes step to visualize an existent target, nonexistent things have been visualized, and reality operates virtually. It means that digital image does not reproduce our reality but reproduces other reality realistically. In other words, it is a virtual reproduction producing an image that is not related to a target, that is to say Simulacre. In the virtually simulated world, reality has an infinite possibility, and it is not a picture of the past and present and has a possibility as the infinite virtual that is not fixed, is infinitely mutable, and is not actualized yet.

This paper investigates how digital technology innovates the aesthetic ontology of film images. The modern civilization of computer and internet bring about the new ontology of film images. Digital hybrid image expands the contradictory combination of physical reality and filmic fantasy. It is inevitable to recount Walter Benjamin' s concept of mechanical reproduction in the age of digital cinema. The modern condition of image arts changes the concept of mechanical reproduction to the logic of digital configuration. In addition, computer simulation innovates the film aesthetics of montage to the aesthetics of digital collage. The technological and aesthetical development of computer simulation and internet network leads to the new ontology of digital hybrid images. This study suggests a new theoretic point that the aesthetic ontology of digital hybrid images leads to the expansion of filmic fantasy and expression.

Digital memory circuits have been developed very fast according to the progress of semiconductor technology. But it was very difficult to memorize a wideband radio frequency signals. Many years ago, an analog frequency memory loop(FML) was used for store of radio frequency signal and the digital radio frequency memory was made according to the development of wideband amplifier and high speed sampler. We present a design of wideband digital radio frequency reproduction device using ladder circuit and the simulation results with respect to the sampling speed in this paper.

The usage of DRM-applied digital contents reduces user's convenience, thus it leads the many users to avoid using DRM-applied digital contents. In this paper, therefore, we propose the new distribution model in which the users, who purchase the DRM-applied digital contents, can resale freely those contents to the other users. As a result, the proposed model induces the users to distribute contents soundly by including them in one of distribution objects. For the purpose of this, in this paper, we propose that a packaged content and usage rights are transferred to another user by using a method which based on some existing digital ticket or coupon. In addition, the security of the proposed system is discussed for the double transfer, the forgery and the modification of usage rights, and the reproduction of contents and usage rights.

Recently, Digital TV viewer have been replacing cathode ray tubes (CRT) with Plasma display panel(PDP). But the chromaticity of the primaries are dependent on RGB input signals. And the colorimetry of PDP changes with gray scale and has a poor performance in color reproduction. In this paper we propose the enhanced algorithm of color reproduction considering nonlinear gamut mapping algorithm. In order to test performance of this algorithm we use the sample colors. As a result of experiments, it was confirmed that the color difference of the digital PDP using the proposed algorithm was considerably reduced.
