NAC Integrates Flicker Supression into Ultra-Slow-Motion Camera

NAC Image Technology has successfully implemented a real-time flicker-suppression system for ultra-slow-motion broadcast HDTV camera systems. NAC’s Hi-Motion IITM allows the operator to adjust the camera “on the fly” during a live broadcast, mitigating and greatly reducing the flicker effect caused by stadium lighting.

In the world of ultra-slow-motion camera systems, images are captured at rates of speed dramatically faster than standard cameras. Stadium lighting cycles at rates much slower than the rate at which ultra-slow-motion images are captured. Because the lights are not synchronized with each other or the cameras, a pulsing effect may be apparent in ultra slow motion imagery broadcast during live sporting events taking place under stadium lighting.

NAC’s unique flicker suppression technology effectively suppresses the impact of stadium lighting with a versatile, easy-to-use manual adjustment. The flicker suppression adjustment is implemented without impacting the workflow of the Hi-Motion IITM.

According to NAC’s Andy Hayford who oversaw field testing in London in July, “we have had technical rehearsals under the lights in a variety of venues, and the response to the flicker suppression feature for the Hi-Motion IITM is overwhelmingly positive! The broadcasters are keen to use the Hi-Motion IITM with flicker suppression because it takes ultra slow motion imaging to a whole new level, especially for the broadcasting of night games.”

The Hi-Motion IITM cameras use a unique three chip (CMOS) sensor capable of capturing more than 10X high speed images in Full HD and provide simultaneous output of live real time video AND ultra-slow-motion replay video. The three chip NAC Hi-Motion IITM cameras provide clarity and detail enhancement along with superb light sensitivity while fitting seamlessly into the workflow of sports broadcast environments.

The Hi-Motion IITM cameras have seen action, around the world, at many of 2012’s preeminent sporting events, including the Australian Open, the Super Bowl, Wimbledon, the British Open and this summer’s games in London. In addition, the Hi-Motion IITM continues to be embraced by broadcasters for live coverage of a variety of professional sporting events, including international motor racing, cycling, tennis, football, baseball, rugby, cricket, golf, boxing, and horse racing.
