LCD 모니터를 활용한 버추얼 스튜디오용 다중 모니터 구현 방법에 관한 연구

초록

The video wall used as a background in the production environment of videos using virtual studios is an essential part of the operation of virtual studios. In the development of video walls, video walls used for background transmission relied mainly on video walls composed of LEDs, as the background screen was composed of modular LED blocks, so it was suitable for constructing large screens because there were no bezel between blocks. Looking at the recent trend of video production, the utilization of virtual studios is increasing, and virtual production is also being carried out in small spaces. In a small virtual space, the gap between the photographer and the video wall is inevitably narrowed, so a video wall with a signage monitor made of LCD is more advantageous than an LED wall with LED exposed during short-range filming. In the virtual studio production environment using an LCD monitor, there was a disadvantage in that the bezel existing in the LCD monitor was exposed, causing an excessive amount of work in selecting candidates for the produced image. In order to minimize excessive candidate selection in a small virtual studio production environment using an LCD monitor or signage monitor, this study began in the process of visually minimizing the thickness of the bezel inevitably present in the LCD monitor Research methods are described in the following order. First, the background and purpose of the study were described. In the actual production environment, the small virtual production space is narrow between the photographer and the video wall, so the bezel of the monitor accompanying the later work of the video work is minimized and the cost-effective hardware configuration is needed. Second, the experimental method for optical minimization of the thinnest bezel among the monitors that can be easily purchased on the market is described. Third, the theoretical background of LED wall and signage was described through theoretical consideration. Fourth, the manufacturing process and its effects were described for the experimental method described in the research method. Fifth, a method of applying the processed structure to the actual situation was described. Through the results of this study, it is possible to improve bezel, which caused excessive late-image work when configuring video walls using LCD monitors in a small virtual studio using general monitors and signage monitors, through visual minimization. Based on these research results, several LCD monitors connected in a small virtual production space could be found to minimize bezel exposure with a lower budget, and based on these research results, a more efficient virtual production environment can be established through follow-up research.
