We are investigating a flicker-free method for video captured at 120-Hz frame frequency to broadcast video during the 2020 Olympic Games in Tokyo. We investigated the cause of flicker generation in video captured at 120-Hz frame frequency and 100-Hz illumination-intensity variation frequency. To suppress flicker generation, we propose a flicker-free method for video captured at 120-Hz frame frequency by using interlaced scanning and an electrical shutter. Experimental results show that flicker in video captured with the 120-Hz flicker-free method is suppressed to one twentieth that by 120-Hz progressive scanning. |
