Abstract

4K high speed camera shooting enables shooting of fast subjects in Full HD 4 times resolution without motion blur due to increase in resolution and shutter speed. However, this shooting incurs several limitations including focus, intensity of radiation and increase in data quantity. As lack of intensity of radiation may occur due to increased shutter speed, it is shoot by opening aperture and limitation in focusing follows. In addition, there is limitation in shooting records since it has restriction in storage due to increased resolution and frame rate. In this regard, this study aims to analyze the limitations shown above through production case of 4K high speed camera (Phantom Flex 4K) and to design effective workflow to overcome this.

4K 초고속 카메라 촬영은 해상도 및 셔터스피드 증가로 인해 빠른 피사체의 영상을 모션 블러 없이 Full HD 4배 해상도로 촬영이 가능하다. 그러나 해당 촬영은 데이터 량의 증가와 광량, 포커스 등 여러가지 제약사항이 뒤따른다. 증가된 셔터스피드로 인해 광량 부족 현상을 가져올 수 있어 조리개를 개방하여 촬영하는 경우가 많아 초점 조절에 제약이 따른다. 또한 증가된 해상도와 프레임레이트로 인해 저장 공간의 한계가 뒤따르기 때문에 촬영 기록에 제한이 따르고 있다. 따라서 본 연구는 4K 초고속 카메라(Phantom Flex 4K) 제작 사례를 통해 위와 같은 한계점들에 대해 분석하고, 이를 극복하기 위한 효율적인 워크플로우를 디자인 하였다.
