  • Under the changing circumstances of broadcasting, this study aims at the corelation of television drama's rating and television image production techniques, analyzing TV image production techniques and TV rating of drama, the highest rating genre. For this research, 6 dramas were selected as samples except the dramas about history and violence on the basis of the TNS media korea's top 100 of the year 2007. This study analyzed camerawork, shot size, shot duration and scene duration with the contents of replay and manuscript viewing of broadcasting companys' homepages. As the result of the analysis of corelation, TV rating is inverse proportionate to multiple camerawork and shot average duration with a very close relationship, showing no relationship with other variables. The result of this study shows that multiple cameraworks and long durated shots should be avoided for higher TV rating.

  • With the increase of weight and influence of TV drama, many researchers began to publish papers on TV drama. However, those papers were mainly focused on social meaning and viewing motives and attitudes of TV audience. However, only a few papers researched about television image production techniques, such as 'Relationship between TV ratings and image production techniques', 'Transition process of TV drama's image production techniques', and 'Comparison of TV and film image production techniques'. According to the recent research on the relationship between TV ratings and image production techniques, TV rating is inverse proportionate to multiple camerawork and shot average duration with a very close relationship. The purpose of this thesis is to analyse the relationship between TV genre and image production technique with the data of top 100 of TNS Media Korea from the year 2004 to 2008. This paper found out that history drama uses more closeup, longshot, tracking and less waist shot than other genres, with shorter shot duration and longer scene duration.

  • The marriage between music and film, both temporal art forms, demands that the inherent aspects of note in each medium are brought into correspondence within a dramatic context. In film-making, the most crucial and difficult problem a film composer faces is finding the music that seems absolutely right for the film and its characters, sequences and dramatic lines. When writing a film score, composers become musical dramatists; some have a special instinct that enables them to find the right kind of melodic line, orchestral texture, rhythmic device and musical style to bring out what they intuitively recognize as the essential aspect of the drama. In this study, several examples are cited - Alex North, Hugo Friedhofer, Bernard Herrmann and David Raksin - that underline this kinetic function of music in film. Effort is made to uncover as many possibilities as possible, so as to arrive at a better understanding of how the two media interrelate for the purpose of emphasizing the dramatic lines.

  • In this paper, we propose a scene adaptive method to obtain two LDR images with proper shutter speeds which capture the irradiance of scene effectively. The proposed method adaptively selects two shutter speeds across the video frame even when the illumination varies continuously. For the performance evaluation, we compute the PNSR to the ground truth which is obtained by the state-of-the-art HDR imaging method. It shows that the proposed method is able to select approximately optimal shutter speeds while avoiding the exhaustive search of every possible pair of shutter speeds.

  • Scene boundary detection is important in the understanding of semantic structure from video data. However, it is more difficult than shot change detection because scene boundary detection needs to understand semantics in video data well. In this paper, we propose a new approach to scene segmentation using contextual information in video data. The contextual information is divided into two categories: local and global contextual information. The local contextual information refers to the foreground regions' information, background and shot activity. The global contextual information refers to the video shot's environment or its relationship with other video shots. Coherence, interaction and the tempo of video shots are computed as global contextual information. Using the proposed contextual information, we detect scene boundaries. Our proposed approach consists of three consecutive steps: linking, verification, and adjusting. We experimented the proposed approach using TV dramas and movies. The detection accuracy of correct scene boundaries is over than 80%.

  • While the broadband multimedia technologies have been developing, the commercial market of digital contents has also been widely spreading. Most of all, digital cartoon market like internet cartoon has been rapidly large so video cartooning continuously has been researched because of lack and variety of cartoon. Until now, video cartooning system has been focused in non-photorealistic rendering and word balloon. But the meaningful frame extraction must take priority for cartooning system when applying in service. In this paper, we propose new automatic frame extraction method for video cartooning system. At frist, we separate video and audio from movie and extract features parameter like MFCC and ZCR from audio data. Audio signal is classified to speech, music and speech+music comparing with already trained audio data using GMM distributor. So we can set speech area. In the video case, we extract frame using general scene change detection method like histogram method and extract meaningful frames in the cartoon using face detection among the already extracted frames. After that, first of all existent face within speech area image transition frame extract automatically. Suitable frame about movie cartooning automatically extract that extraction image transition frame at continuable period of time domain.

  • Given the recent trend of natural planting, the recognized needs for new landscaping plants that have advantages in terms of climate change and maintenance, and expected increases in demands for grasses in Korea, this study is intended to investigate from the design point of view the techniques to use grasses and their significance through garden design by Piet Oudolf who is attracting international interests with the use of perennial plants and grasses and is leading the trends in modern planting design, thereby answering the question: how to best use grasses in landscaping spaces? The characteristics of Oudolf's garden design using grasses are summarized in the following conclusions: First, Oudolf combines perennial plants and grasses to make one-to-one correspondences or express expanded drifts. Here grasses mainly serve as an element to change over to other spaces or as a connecting element between image transitions. Second, the brown color and texture of grasses represent Oudolf's considerations on the temporal continuity of gardens. They express the lyricism and pictorialism of autumn and winter. Third, grasses serve to set layers in wide areas resulting in discordance between viewpoints and circulations. Oudolf repeatedly cross perennial plants and grasses using matrices, islands and distributed layering. Here grasses are used to express abstractive meanings in the settings of scenes.

  • When making a comic film, the comic presentation that uses stress and exaggeration is the important subject among other things. In this study we tried to investigate the comic effect using the movement of three-dimensional shot. To conduct this study, we extracted the shot manufactured through the Flow Motion of a 3D Production Program Virtual Camera and a High Speed Motion Picture Camera. The shot manufactured applying this manufacturing skill and using three-dimensional production method for the video contents efficiently made was classified into several scenes. The focus of this study is to search for the factor that makes the atmosphere of a story comic through three-dimensional production shot. According to the shot analysis, three-dimensional production method plays a role in developing more stories on space and time by visualizing stories in three dimensions, which makes the most use of the movement of camera, lens and the utilization of focus. In addition, in the presentation where many comic and exaggerated factors are provided, we used the technology that stresses a scene using the size of a shot and the lasting time and presented the method that exaggerates space using a 3D Production Program Virtual Camera and a High Speed Motion Picture Camera. By reviewing the qualitative improvement and the efficient method on making comic films through the possibility that the atmosphere of this three-dimensional shot can apply to the effect for comic presentation, we tried to approach the comic presentation.
