From the year 2009, 3D Stereoscopic movies and TV have been spotlighted after the huge success of a movie called "AVATAR". Moreover, most of 3D movies & contents are created by mixing real-life shots & virtual animated pictures, such as "Robocop 3", "Transformer 4" as shown in 2014. However, the stereoscopic 3D video film shooting with a traditional stereoscopic rig camera system, takes much more time to set the rig system and adjust the system setting for proper film making which necessarily resulting in bigger cost. In fact, these problems have depreciated the success of Avatar as decreasing demand for 3D stereoscopic video shooting. In this paper, inherent problems of traditional stereoscopic rig camera system are analyzed, and as a solution for the problems, a novel implementations of single-lens optical stereoscopic 3D camera system is suggested. The new system can be implemented to a technology for separating two lights when even those lights passing through in the same optical axis. The system has advantages of adjusting the setting and taking video compared with traditional stereoscopic 3D rig systems. Furthermore, this system can acquire comfortable 3D stereoscopic video because of the good characteristics of geometrical errors. This paper will be discussed the single-lens stereoscopic 3D camera system using rolling shutters, it will be tested geometrical errors of this system. Lastly, other types of single lens stereoscopic 3D camera system are discussed to develop the promising future of this system.

Portable embedded systems have recently become smaller in size and offer a variety of junctions for users. These systems require high performance processors to handle the many functions and also a small battery to fit inside the system. However, due to its size, the battery life has become a major issue. It is important to have both efficient power design and management for each function, while optimizing processor voltage and clock frequency in order to extend the battery life of the system. In this paper, we calculated the efficiency of power in optimizing power rail. This system has two microprocessors. One is used to play music and movie files while the other is for DMB. In order to reduce power consumption, the DMB microprocessor is turned of while music or videos are played. Lastly, DVFS is applied to the processor in the system to reduce power consumption. Experimental results of the implemented system have resulted in reduced power consumption.

In this study, we apply the facial Facial Action Coding System for coding the muscular system anatomical approach facial expressions to be displayed in response to a change in sensitivity. To verify by applying the virtual character the Duchenne smile to the original. I extracted the Duchenne smile by inducing experiment of emotion (man 2, woman 2) and the movie theater department students trained for the experiment. Based on the expression that has been extracted, I collect the data of the facial muscles. Calculates the frequency of expression of the face and other parts of the body muscles around the mouth and lips, to be applied to the virtual character of the data. Orbicularis muscle to contract end of lips due to shrinkage of the Zygomatic Major is a upward movement, cheek goes up, the movement of the muscles, facial expressions appear the outer eyelid under the eye goes up with a look of smile. Muscle movement of large muscle and surrounding Zygomatic Major is observed together (AU9) muscles around the nose and (AU25, AU26, AU27) muscles around the mouth associated with openness. Duchen smile occurred in the form of Orbicularis Oculi and Zygomatic Major moves at the same time. Based on this, by separating the orbicularis muscle that is displayed in the form of laughter and sympathy to emotional feelings and viable large muscle by the will of the person, by applying to the character of the virtual, and expression of human I try to examine expression of the virtual character's ability to distinguish.

This paper derives the mutual relationship between film and installation art through specific case studies about the point of the intersection of the two genres. It needs to find the relationship between art painting and photography and the relationship of silent film and the relevance of the work of art in the 1920s. After painting over the installation exploring the relationship of art and through the mise en scene of the film, ie, the screen image of the configuration and deployment, or cinematic work of art for the film can be found in the application of practices. First, in Chapter 2, this study works of art practices through the analysis of film and the interaction between the two genres based practices for secure sex. In Chapter 3 the movie 'Wonderful Life' and installation art work "hand memory" through the analysis of the two cases specifically for the point of intersection analysis. 'Wonderful Life' and 'hand' Remember each subject and conceptual work in terms of 'memory' that it is represented on similar, but, film and installation art genre caused by the difference in the way the media represented by the results of the different forms of otherwise appear. If so, this study film and installation art practices through the comparison of cases to derive mutual relationship by analyzing two cases in detail what each of the different looks at whether any similarity in that.

The virtual reality (VR) cartoon is a format of VR contents that leverage the characteristics of webtoons that provides the simple story line and graphical storytelling tools to strategically surmount limitations of VR contents design. The VR cartoon enables people to experience the imaginary three-dimensional space in the webtoon as a real space by the transformation of webtoon contents through VR prototyping. The VR cartoon successfully presents focused environment where people can readily pay attention to the contents without notable motion sickness. People have been familiar with the storytelling strategy in the context of published cartoons and webtoons, likely we've understood the narrative of a movie through the continuous scenes projected in the screen. Indeed, it has been recognized as a popular toolset of communication, where visual images are sequentially delivered by replacing multiple planar spaces to tell a story narrative. While there are discrete panels with the time and space resolution in the graphical cartoons, people can distill a commit closure based on their past experiences. This is a typical "grammar" of the cartoon, which can be extrapolated to the VR cartoon that provides a seminal storytelling strategy. In this article, we review how the storytelling strategy in webtoons has been transformed into that in VR cartoons, and analyze the key components of VR cartoons. We envision that our research can potentially create keystones to produce variety of new VR contents by reflecting various narrative media including cartoon as a 'sequential art'.

Owing to the latest development of component and media processing technologies, UHDTV as a successor of the HDTV is expected that this will be coming soon realization. Accordingly, an audio technology that provides a 5.1-channel surround sound in home should be contemplating on what services should be provided with the advent of UHDTV era. In fact, however, the market of 5.1-channel audio is struggling, due to the difficulty of installation and maintenance of the multi speakers in a home. Meanwhile, the movie sound market for a long time been used in 5.1 and 7.1-channel sound formats, have changed as Dolby ATMOS, IOSONO, AURO3D etc. are launched one after another with the introduction of hybrid audio technologies that include the ceiling and object-based sounds. This very object-based audio technology is assured to be introduced in the home theater and broadcast audio market, and this change in audio technology is expected to be a breath of pioneering technological advances and market growth from the channel-based audio market that lacks flexibility. In this paper, we will investigate a suitable realistic audio solution for UHDTV, and introduce hybrid audio technologies, which is expected to be an audio technology for UHDTV, and we will describe the hybrid audio content format and reproduction methods in a home and consider the future prospects of realistic audio.

This essay is about the considering the mutual relevance of animation and literary work in a case. The television animation Heidi, Girl of the Alps made in Japan is the most famous media version of the original novel. The novel Heidi by the Switzerland writer Johanna Spyri has been translated in a lot of countries, and the original Heidi has been adapted for mass media - literary(translation), movie, play, animation, cartoon, picture book. Here, with the relation between animation Heidi, Girl of the Alps and Spyri's Heidi and the present condition of the change in Japan and Korea, the relevance of animation and literature was reconsidered. First, Heidi, Girl of the Alps and Heidi have the different characteristic as media, and the content has some different set-up. On the other hand, original soul is inherited in the animation. Second, the animation has affected Heidi related visual image and the original media diffusion. The above consideration from a viewpoint of the mutual relevance between media shows the importance to return aiming at mutual understanding of animation and literature and mutual value between the diversified media. Moreover, it suggests a possibility of leading to creation of the energy which results in transformation also to action.

The objective of this study is to examine the effectiveness of signals and advancing our understanding of the relationship between ratings and audience decisions based on the signaling theory. Though many studies argue that information asymmetry affects decision making, few studies have examined two key signaling factors: its potential to have multiple sources and the effect of time on its effectiveness. This study examined how experts' and the general audience's ratings affect decision making. We also considered change patterns in ratings to explore how time effect on ratings affect selection behavior. We tested our hypotheses using the latent growth model based on signaling theory and behavior approaches. The results show that a general audience's ratings is perceived as more credible than are those of experts and that audience members are significantly affected by upward patterns in ratings. The findings suggest that general audiences play a critical role as signal providers. Thus, market participants such as producers should pay more attention to the general audience's ratings in order to increase revenues. They should also consider the time effect of signaling, such as upward trends in ratings.

Study about existence of illusion which human beings feel from imitated image based reality have been continuing by copy theory and conventionalism for a long time. Traditional copy theory which had controlled representation theory from plato have explained illusion by similarity of image and representation objects. According to copy theory, image is natural sign unlike language but the late in the 20th century, conventionalism from N, Goodman insists they are not any special similarity between image and representation objects. They insist image and conventional sign just as language. These opposit theory rearranged conventionalism by the entrance on the cognitive science. The copy theory couldn't explain the problem of representational gap between reality and duplication, but photo media makes new paradigm about theory of the illusion. The problem of representational gap was disappeared by CGI images on the base of digital media. We are exposed exquisite duplication for a example, movie, advertisement, printings. Sometimes duplications are more real than the original works. Digital is a non-material object by 0 and 1. Specially real lighting skill and mechanism are copied perfectly by photon mapping skills and the duplications are produced more real than the original works. By disappearance of representational gap, we need new theory model for explaining of digital illusion and copy theory can be the key.

In this paper I proved that the intention of the movie is to put the reader at the crossroads of choice, which is still in progress, in this context confirmed that the storytelling is very enlightening and popular. This was demonstrated by the thing of making a story the charactor's Affects process itself in the story and a change in the point of view from witness to participant in the discourse. Jang Hoon seeks to reconstruct the Gwangju Democratic Movement through Kim Man-seop, a character who now lives here with trauma. Faced with a sympathetic message from a common and familiar figure around us, such as a taxi driver, it should be said that the goal was to get the audience to accept past gruesome incidents as part of us. The film uses Affects as a way to make the 1980s "Them" become "we" and replace the 37-year-old incident with our modern story. Soon, the film's intention is to turn Gwangju's Democratic movement from "There, Their Story" to "Here, Our Story." That's why popular storytelling was needed and concluded that it was the popularity the film acquired.
