About

Miwa Katayama is a researcher in computer vision and interactive media, best known for pioneering accessible approaches to cinematic visual effects. Her most cited work, "Bullet time using multi-viewpoint robotic camera system" (2014, 9 citations), addresses the challenge of generating the iconic "bullet time" effect—a slow-motion, time-sliced view of a dynamic scene—without the extensive pre-production and complex setups typically required. Katayama’s major contribution lies in designing a practical, generic system that uses a multi-viewpoint robotic camera array to capture moving subjects in 3D space, enabling real-time or near-real-time rendering of bullet time sequences. This innovation significantly reduces the time and expertise needed for advance preparation, making high-end visual effects more accessible for small studios, educators, and researchers. By focusing on usability and automation, her work bridges the gap between professional filmmaking tools and academic or hobbyist applications. Katayama’s research has been cited in studies on robotic cinematography, multi-camera synchronization, and immersive media, underscoring her impact on democratizing advanced visual storytelling. Her achievements highlight a commitment to practical, user-friendly systems that expand creative possibilities in computer graphics and interactive entertainment.
